One reason is that >I have so many and the PAR format is so compact compared with decent >resolution GIFs. I do, however, claim copyright on my images. By circulating >them only as PAR files (which have to be generated by Fractint) the >copyright comment is there for the user to see. Les sent me par files for 52 images. It did not take long to look them over. Very nice. I replied to him with the following, which I am posting here because I have some questions about one of the formula. Hopefully, someone on this list can answer. The formula produces intriguing patterns - I currently use an example (Partwave, see below) as my screen back ground. -- -- Now folks, these are a great series, really. One of my favorite images is a variation, or a reverse zoom (zoomout) of Les' "Parting of the Waves (ti_mod07). What I like to do to these and FotD images is zoomout and look around a bit. See if there is some interesting mathematical implication or another nice image in another corner. I've put some of these explorations on my web page: http://www.geocities.com/CapeCanaveral/Lab/3825 Parting of the Waves zoomout looks like a modified MSet image with rays going out all around, but some are under splotches. The cardioid has radial bands of color but all other components including mini-cardioid have circular banding. BTW, as a long time DEEPZOOMer(TM), I saw someone calling a 10^^300+ midget a minibrot. Well, in the age of nanotech, I suggest we call these nanobrots. :-) Here is the file for FRACTINT 19.6. I'd sure like to know what is going on here. I read formula tutorial and the fractint.doc and understand a some math. But that just does not seem to be enough for me. So please allow me a few questions. Questions: Why the rays? Zoomout shows it is related to the angle where c is. But how does z[n] map to these angles? That is, how does the final exit select a color based on angle? The rays are fractal, splitting as they approach the MSet. If you can follow one, you will end up at a mininbrot. Why the splotches? Zoomout even more and we see a band (width -45i to +45i) going from -inf to +inf. The band is made of these splotches which near the real line get so narrow that Moir? patterns take over. The splotches are mapped all over the image as you zoom in near the MSet. Why the banding in the components and where are the splotches? I would have thought the components would have them. And why is the cardioid different from all other components? It must be a bof60 thing. :-) Turning it off leaves the cardioid banded. And finally, if you zoom into a spiral, you often run smack into a round spot. An example is Blackhole (see below) where I follow a ray into a spiral and there it is, a spot blocking exploration which is unlike the splotches mentioned in the previous questions. Unlike the fake MSet zones of black which go away with higher iteration limits, this one is persistent. What is it? Can we make it smaller and even go away? Thanks, Les, for the great images! Hopefully Les St Clair or Jim Muth or some of the other experts can help me understand.

I work as a software engineer in computer graphics (we make a program to paint textures directly on the surfaces of 3D models for SGI workstations), and when I get some time I create whatever I can manage with fractals. I tend to explore the complex exponential julia sets (z <- lambda * e^z + c), among other things. I've only been using fractint for a short while; mostly I have been writing my own code and rendering techniques. I wrote the call for votes that created sci.fractals on usenet and its subsequent charter. That was a few years ago; now I avoid usenet because of all the spam issues, unfortunately. I've taken enough mathematics to be able to read (and understand! :) Beauty of Fractals, which is quite dense indeed. It took me a few courses in topology and fractals in general before I understood some of the things Peitgen talks about in that book. Until the last few years, I didn't have an IBM PC to play with fractint much, but I did sneak a few tastes on other people's computers. (I used to own an Amiga.) My interests are in the mathematics and rendering of fractals. I've written a little perl script that creates a DOS fractint batch file from a par file, if that is of interest to anyone. -- ``Between stimulus and response is the will to choose.'' -- Steven Covey =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 3D Paint: The Power to Create in 3D; Rich Thomson email me for more info rthomson@ptc.com Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Sylvie Gallet Subject: (fractint) Welcome folks!

It is a much needed Internet-wide forum for discussing Fractint-specific topics for those who can't or won't join Compuserve. The online world is inexorably moving to the Internet, even CompuServe, so forums limited to one service provider will slowly but surely fade into the sunset in the next couple years. Tim's mailing list is, as I understand it, the interim step in this inevitable evolution. As the administrator for the Fractal-Art mailing list (to subscribe, see my .sig below), I hope that both lists will be able to serve the fractal enthusiast community, each in their own unique ways. As some may know, I've sort of frowned upon overly Fractint-techie talk on Fractal-Art for various reasons I won't go into. Tim's list is the natural and appropriate outlet for such topics. And I do plan to post every once in a while to Fractint(-list) since I mostly use Fractint. With that, I'd like a definitive answer to my Fractint-specific question. Does Intel's new MMX technology affect the accuracy of Fractint, or does it have no effect? Has anybody here done actual tests? Thanks.

I guess I should respond to my own prodding I've been a Fractint developer since version 6 or so and am currently the developer team coordinator. Fractint development continues, but it's much slower than it once was. As always, we have more ideas than time or energy, but once in a while we get code contributions that prod us on, or find a burst of energy from somewhere. I am a software developer at the Johnson Space Center working for the United Space Alliance. I am a mathematician by training. I have written 5 Fractint-related books. The first several were best sellers when they came out in the early 90's. They all went out of print when Mitch Waite sold out to MacMillan. My favorite was Fractal Creations 2nd Edition. Because the book market is now so internet oriented, there is no hope for more books anytime soon, though if we ever port Fractint to Windows, there would be a small window of opportunity to do a book targetting whatever the latest and greatest Windows version is. At the present time I am very happy to NOT be writing :-) But I sure wish Fractal Creations was in print. It's a good book. It even has an appendix on hypercomplex fractals, my modest contribution to the literature. Things in the works at the moment for Fractint: There will be an "evolver" feature that fills the screen with thumbnails of variations that change a particular parameter. Robin Bussell contributed this, and several of us are helping with it. At long last we have some SOI (Synchonous Orbit Iteration) code that greatly speeds up some deep zooms. It is based on code by Michael Ganss, who wrote AlmondBread. This isn't too well integrated yet. What I obviously need to do is port the logic to arbitrary precision, since SOI is nmost useful for very deeps zooms, and since deeps zooms are slow and could use some speedup! It remains to be seen how well this would work, but I have high hopes. We can also make SOI function with any fractal types. Whether the algorithm will actually *work* with other than Mandelbrot/Julia is anyone's guess Well, that's enough for now.

When I zoom in to the deepest zoom supported by floating point (I have a P90/Win95 setup) the M-set looks fine, zoom in any deeper (tab shows "16 digit arbitrary precision" or something like that), then the screen draws in a constant color. Zoom back out again and the M-set comes back. I also have noticed that a bunch of the images in the various PAR files being distributed around compute out as a constant color screen for me. Does anyone else have this problem? If it would help, I can send someone a GIF file saved of one of my constant color screen situations. -- ``Between stimulus and response is the will to choose.'' -- Steven Covey =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 3D Paint: The Power to Create in 3D; Rich Thomson email me for more info rthomson@ptc.com Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Jay Hill" Subject: Re: (fractint) Welcome folks!

Hill, Jay.R.Hill@cpmx.saic.com and http://www.geocities.com/CapeCanaveral/Lab/3825 and it is not a a phony identity as Paul Derbyshire suspected in sci.fractals. I first got on the net about 4 years ago when I was pushing DEEPZOOM and computing the area of the Mandelbrot Set (which I'm still doing, BTW it is at least 1.5063036). You think you have examined a lot of nanobrots, how about 65243? Here in San Diego, I have been glued by fractals to one computed screen or another since I first coded the MSet on my 8080 5 MHz 320x200 CGA DOS machine more than 10 years ago. The machines are what - 1000x faster and has that satisfied? NOT! Do any of you still have floppies storing fractals that took 2 days to compute (but now would take less than a minute)? And worse still, stored in EGA? Yuk! Oh well, we always think the latest image is the greatest thing but then we never look back. So many new ones appearing everyday. I do still have 'partwave' as my screen 'background' (see my web page) but Sylvie's might push it off for a few days. :-) Wooop! Er.... Oh OK, Sylvie's is now the wallpaper.

Location: Bristol, south west England. Physical attributes: height (lots), Hair (long), Grin (constant, hairy too), Glasses (round). Occupation: far too many things at once but mainly computer support. Current philosophical preoccupations: feedback, boundary conditions, randomness combined with the aforementioned. Fractal stuff: I first came across the marvels of the Mandlebrot set while playing with Transputers around 1984-5. I started coding fractals as a start in learning C coding for a project which has since been swept aside :-) . After discovering fractint at version 11 ish I embarked on a fanatical search for the source code amoung local BBS (hey! remember those? ) as a CIS account was out of reach at the time. Having achieved the holy grai, with teh assistance of some generous sysops I dove into the maze of code that is fractint and implemented my first feature.. autologmap! there then followed the freestyle mode for palette editor and with the help of the wonderously kind Dorothy Gibbs, sysop of pandoras box BBS, I made finally the credits of version 18. Since then I've thrown the image browser into the soup (marvellously reworked into something useable by Jonathan Osuch) an am working on another bizzare feature to be added real soon now! I'm a user interface hacking type dude rather than a mathematical boffin and have the most extreme respect for the rest of the team that hold the whole magnificent ediface that is Fractint together. Oh yeah and I still try and find time to generate some pretty images from time to time tough never approach the dizzy heights of the true masters ( LS, SG, BC, CP to allude to but a few... I'm sure you know who they are! ) Obligatory web page: http://web.ukonline.co.uk/members/robin.b2/olig/olig.htm Other interests: Kites (esp the large 'beach skiing' variety), old style analouge 'music' synthesis, reading far too much email :-) I've just completed a very pleasant summers night in the garden, coding fractint on a laptop by candlelight (and discovering that I can type 'makefrac' and 'f_errs.txt' in the dark by muscle memory alone :-) ) and drinking a variety of interesting bottled ales (variously organic and light, jacobean, dark and spiced, and even chocolated flavoured) I'd like to be able to say that this missive was keyed in thus but I couldn't get the phone line out there, maybe next time :-) Well think that about summs me up! any questions? Tim, on an administrative note, will this list be available in digest form? and what about archives available on the web? Cheers, Robin.

I thought I would wait for a few days for people to join up before posting. My Name is Noel Giffin and I've had an interest in fractals from reading about them in Scientific American in the late 1980's. I played around in fortran originally creating my own fractal programs, making lots of mistakes and getting confused at strange results for awhile, before I really understood what I was doing. I switched to Fractint around version 15 because I couldn't resist the temptation of the formula parser. What, I don't have to compile every time? From the alt.fractals and then the sci.fractals newsgroups I came in contact with all these crazy people who were interested in this subject as well. I started an ftp archive for fractals in the early days of the internet and later turned that into the Spanky Fractal Database and webserver. Thanks again to everyone who has contributed and made it such a success. I maintain the Fractint web pages as well. Sorry if people here have emailed me and I haven't responded or not taken up all your material and ideas. It keeps me so busy, I barely find time to make any of my own fractals. I work at TRIUMF which is a 500 MeV cyclotron on the University of British Columbia campus in Vancouver, B.C. Canada. I've been working around computers since my college days in Ottawa, where I learned on DEC pdp-8 and IBM 1620 machines where 4k of core memory was something that you could hold in your hands and marvel at the maze of beads and wires. Life was so simple then. So what if it took two days to punch your program onto cards only to drop them on the way to the machine room. So that's what sequence numbers were for? I'm really glad Tim started this list. I've never had a CIS account and I've always felt a little like an outsider, knowing most of all the ideas and development for fractint was done there. I hope a little of the discussion and technical fractal topics will now spill over here as well.

When I first found Fractint, v12, I thought that Stone Soup Group had foolishly mis-typed--it was *obviously* version 1.2; no good program could have *twelve* versions! :-) Kerry Mitchell lkmitch@primenet.com Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: NOEL_GIFFIN Subject: RE: (fractint) ParToBat Date: 13 Aug 1997 10:03:03 PST Hi, Michael Peters sent me partobat v. 3.4 in May of this year.

I reside in a large, (too large in fact), East Coast city of the USA, where I spend most of my idle hours searching for those elusive great fractals. Those of you who are members of the Fractal-Art mailing list are already familiar with my work. It appears as the "Fractal of the Day", which I've been posting to that list for several months, and will continue doing so. But in addition to the artistic aspect, fractals also have a math- ematical and philosophical aspect, and it is these aspects which I will emphasize in my posts to this list. Like many of you, I learned about fractals from the articles which appeared in Scientific American Magazine in the 1980's. But it was not until 1987 that I actually began working with them on a clunky old 8088. Even now, I am still using a 486, but I am ready to purchase a new machine as soon as I determine which processor runs Fractint the fastest. My particular fascination with fractals lies in the fact that they are multi-dimensional. The assemblage of Julia sets comprises a four-dimensional object known as the julibrot figure. The assem- blage of perturbed Mandelbrot sets also comprises a four-dimensional figure, the same julibrot figure sliced from a different direction. But in addition to these two directions, there are four other perpendicular directions in which the julibrot may be sliced in two-dimensional slices. It is these other directions, as well as the oblique and skew directions of the julibrot that I am most interested in. Before I go, I'd like to tell my most wished-for Fractint feature -- a simple text editor included as part of the program. This would eliminate the constant switching of programs when fine-tuning formulas. See all of you soon. Take care.

I've been using Fractint on and off since the late 80's. Fractint has taught me lots about fractal math as it drew pretty pictures. It's good to see that there is now a list devoted to the program. (Thanks, Tim.) I hope to learn more as questions are asked and answers are supplied on the list. My interest is in Iterated Function Systems. IFSs are something that Fractint is not quite as useful for as it is with some other fractal types. This isn't a complaint, but it explains my on and off Fractint usage. Perhaps, as I get the time, I will propose some possible improvements to Fractint in this area. In the meantime, I have been working on my own software to investigate IFSs. While this means that I don't have as much time for Fractint as I used to, my continued interest in Fractint has at last moved me to add a feature to my IFS software to produce 19.6 par files. This will allow me to share my IFS creations with others. Anyway, IFSs continue to hold my fascination and I look forward to running into other IFS aficionados on this list who might share their IFS experiences with us.

We're fairly early in the development cycle right now. Maybe I shouldn't have tantalized you with upcoming features :-) I have thought of releasing more often. On the WWW many authors release beta versions every few weeks. However, I've heard the opinion expressed that this is a bad trend as it turns the public into beta testers and encourages sloppiness. While we have released versions with bugs that forced a new version in a few days, we try to keep Fractint as solid as we can. Also, since we are volunteers, more frequent release exposes us to the possibility of more support for versions that only last a short while. This is worth discussing more, maybe we could release somewhat more often than we have recently.

If you see people discussing some message posted before you subscribed, so you don't have a copy, just check the archive. There is also a digest list. If you subscribe to fractint-digest the same way you subscribed to this list, you will get digest messages with a number of messages combined. This reduces the quantity of messages you get at the cost of the size of the message. Plus, of course, you can't post to the digest list. I can set how often the digest messages go out etc., but so far I haven't changed the default way majordomo set this up. Looks to me like the archive is more useful than the digest idea.

I'm afraid so, though there's always the shell to dos key (d I believe), though you then have the task of remembering what that file name was.

Just to add my voice to this, I also have a similar problem, although I can't recall a particular one off the top of my head (since I tend to just give up :^). I had a possibly related problem of when I used the unix port, and saved a par file, if I tried to reload it, in either the unix port or DOS (19.6), it would compute out as a constant color screen. -- Melissa Binde -- binde@cs.swarthmore.edu Outside the Asylum -- http://www.terindell.com/asylum/index.html Babylon 5 Weekly Column -- http://babylon5.miningco.com How many developers does it take to change a light bulb?

Date: 14 Aug 1997 11:36:12 -0600 (MDT) Tim suggested self-introductions, so.... My name is Jason Hine, and I'm a recent graduate of Colorado State University, USA. I focused on Geographic Information Systems (GIS) and their applications to natural resources during my undergrad career. When i return to grad school, it will be to work on incorporating fractal theory into GIS. In the meanwhile, I'm working on a couple C++ programs which will work in conjunction with Fractint. The first program, already under construction, allows unmanned deepzooming into the mandelbrot (and possibly other) fractal(s). The first version of that program, called DEEPER, had some major bugs, including a hefty memory leak... the source code for DEEPER is available from my page at http://boralf.agsci.colostate.edu/~jason The second version, which I've just begun, will have a fair amount more functionality than the original, including some pattern recognition abilities which will allow the program to 'lock on' to a prime spot for a mini-Mset, and dive until it reaches it. I'll keep you posted. The other program, which is still only in my head, would take saved images of two mini-Msets and rotate/zoom one of them so that it matched the other in both size and orientation, allowing the user to then perform various operations with the two images to find differences and similarities between the two. I'm looking forward to the opportunities which this mailing list will provide us all with! If anyone else out there is into GIS, I'd love to hear from you personally. Take care, everyone!

This is much requested by users, and much resisted by the usually-responsive developers The fact that Fractint still works at all is a technical miricale. It has grown many times bigger than the DOS 640K limit. (A trick called "overlays" permits this.) We're reluctant to add complications that are not essential because the program is already so big. If and when Fractint is ported to Windows (a new port, not the old Winfract) this would be easier to do. Having said that, if someone comes along who both wants more file management and editing from within Fractint AND has the programming skills to do it, it will probably happyen. In my case, I have a backlog of ideas going back years, and would rather spend my time giving you truecolor support, PNG support, better 3D rendering , or whatever than file management Tim Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Tim Wegner" Subject: Re: (fractint) Wish list Date: 14 Aug 1997 18:53:05 -0600 Rich wrote: > Ah, so you could program the lorenz attractor by entering the formula > for the 3 variables? Yes, that would be useful :) This would be really easy, with one caveat: the formula parser uses complex math. Most Lorenz-type formulas use real formulas for x and y, so it would not necessarily be easy to code things up in the parser. Another related feature for the parser would be some kind of variable declarations that would permit real variables. In the meantime, it is probably possible to cheat and use the real() operator, wasting a complex variable and using it as a real variable. Inefficient, but effective. There is a crude way to do this now: use the orbits feature with a formula (the command.) I believe that this Lorenz fractal use of the formula parser would not be hard to implement. We've just never tried. The orbit feature (in jiim.c) does something very similar. That code could be stole3n and re-used with some modification to make an orbit fractal type using the parser.

Kerry, great minds think alike We have implemented something like this in our developer version. Only we did it my having a special designated parameter. In the z^2 +c formula, the Mandelbrot-Julia relationship makes use of two different uses of the parameter c. In the Mandelbrot case, it is initialized to pixel, and in the julia case it is a constant parameter. (I know you understand this basic point, I'm just trying to explain how we implemented your idea ) So we created a pre-defined constant ismand, which is 0 for julia and 1 for mandelbrot. You can use the new if else endif feature to test ismand, and initialize c differently in the two cases. The space toggle toggles the value of ismand. What do you think? (Lest anyone misunderstand, this hasn't been implemented yet in 19.6!)

I can trace my downfall back to Aug of 1985 when Sci. Amer. came out with the first article for the public on fractals. After some false starts my first fractals were 64X64 plots using colored characters to represent pixels. Have gone through 5 printers up to now with a Cannon 4550. Haven't been able to get any good 11X14 paper yet so can't judge it. Have been very satisfied with an HP PaintJet XL. What I want to propose is a test that will tie a fractal speed rating to a computer. I have juggled the numbers in this parameter file to run in exactly 100 seconds on my Quantex Pentium 90. (Well, actually 100.02.) The formula is in the Orgform compilation but here it is in 19.6 form just in case someone doesn't happen to have it. test { ; P90 1024X768 time 0:01:40.02 reset=1960 type=formula formulafile=_p.frm formulaname=Prop passes=1 center-mag=+1.09809204844546600/+0.15284814152098180/77.28729 float=y maxiter=497 periodicity=0 colors=0000000e00eee00e0e00z<20>zzz<15>z44zg0z20z30zg0z50z60zg0z80z90zg0\ zB0zC0zg0zE0zF0zg0zH0zI0zg0zL0<38>zx0zz0zz0<150>zz0 } frm:Prop (XAXIS) { z=0 c=pixel: z=sqr(z); z=-z; z=conj(z); z=z+c, |z| <=4 ;SOURCE: crocker.frm } On an AMD DX4-120 it took 2:15.23. The Pentiums are obviously appreciably more efficient. The question is what about the newer Pentiums and other variations. I have been toying with the idea of getting an AMD K6-200. Rhe formula came from my first program where the ROM routine was supposed to subtract b from a but actually subtracted a from b, which reversed the sign of the real part of Z^2 on every itteration, which is the only difference from the classic Mandelbrot. It has perfect 3 way symmetry. Find an interesting detail and you can calculate precisely where 5 rotated copies are located. My favorite view of this formula is centered at (1.17484/.17799) Mag 109. The above color scheme was intended to go with this view. I balk at giving my pictures names. For one reason because several people have radically different impressions of what this may represent. Enough for now. My wish list is coming.

Specifically, is the iteration number for each pixel a direct interpretation of the actual number of iterations calculated for each pixel?

I know the book that originally was written to accompany the program is long gone out of print because I've been searching for it. Is there a good general tutorial on the program out there?

I have some concern for existing features like colour cycling and palette editing, if true-colour displays are adopted. Won't Fractint have to switch graphics modes to utilize both truecolour and palette editing? Isn't this rather a problem in the windows 3.1 and win95 environment. I'm not sure about win95 but I know that windows must be restarted after switching video modes. This makes this type of dual support next to impossible to implement in a program.

May? Computers only handle what is currently possible with the software because we keep the requirements down to what they can handle. With fractint's current zoom capacity of 10^1600, it is already beyond the capacity of computers to produce the entire standard mandelbrot image at 10^1600, in 1024x768 chunks. Math is bigger than physics and everything that inhabits its realm. Now, finding images worth doing, slow or fast, is another thing entirely, and one that Lee Skinner (among many others) does much better than I. -- Mike Traynor People who like this sort of thing will find this the sort of thing they like.

For a windows/win95 environment, there are two approaches: 1. require the user to set their video mode to what the program wants. 2. require the program to conform to the video mode the user has set. I personally am annoyed by programs of the #1 flavor. For fractint to be a #2 flavor, this means that: a) "truecolor" renderings would have to be dithered to the current color palette on a screen that isn't in truecolor mode. b) color cycling would either be emulated or disabled when you aren't using a palette mapped display. Note that palette editing can still be done and applying a colormap to an image can still be done, but the operation is more complex than simply modifying the CLUT on the video card. These are just the facts of life under Windows. For DOS, its conceivable you could switch to the truecolor video mode; but again, you wouldn't have color cycling via the hardware in 24-bit mode. It can be emulated, but the emulation is so slow at that point I don't think it will make people happy. PC busses are just too slow for 24-bit color cycling emulation. Think of fractint like this: color palette -+ | V parameters -> "fractal" -------> frame buffer ----> image (iteration count) fractint uses the video hardware to handle the last stage of that pipeline -- mapping iteration counts to colors. When in 24-bit mode, the palette editor and so on can still be used, but in that case fractint itself must take the iteration count and pump it through the palette table to get the 24-bit pixel that is stored in the frame buffer. Similarly, when viewing 24-bit images under a limited color palette, fractint could do the obvious thing of picking a video hardware palette that selects the "best" 256 colors to represent the 24-bit image in a dithered fashion. Even here "palette editing" is useful, because the palette defines the transformation of an iteration count into a pixel. Furthermore, this view of a palette leads to palette depths limited only by the memory on your machine. The fact that palettes are 256 entries deep is an artifact of fractint's assumption that a palette used to map iteration counts to (R,G,B) values is identical to the palette used by the video hardware on a PC. This is a reasonable assumption for most programs. Once you divorce this notion out of your code, you can have code that uses the hardware when possible, but isn't simply SOL when the hardware doesn't fit your model exactly. I think the biggest thing limiting the future of the DOS fractint is its memory consumption and not its use of truecolor vs. 8bit. At least that's how I understand it from recent comments from Tim :).

Platform MS-DOS, Macintosh, UNIX, Amiga, others Supporting Applications Too numerous to list See Also Chapter 9, Data Compression Usage Originally designed to facilitate image transfer and online storage for use by CompuServe and its customers, GIF is primarily an exchange and storage format, although it is based on, and is supported by, many applications. Comments A well-defined, well-documented format in wide use, which is quick, easy to read, and reasonably easy to uncompress. It lacks, however, support for the storage of deep-pixel images. Vendor specifications are available for this format. Code fragments are available for this format. Sample images are available for this format. The following software packages can process this format: Microsoft Windows Software: • CompuPic • Graphics Viewer • GraphX Viewer • Graphic Workshop for Windows • LView Pro • Paint Shop Pro • PhotoLab • Picture Man • Ulead Viewer • VuePrint • WinJPEG MS-DOS Software: • Graphics Display System (GDS) • gif2dxf • Graphic Workshop • IMDISP • PICLAB • QPV • VPIC OS/2 Software: • GBM (Generalized Bitmap Module) • PMJPEG (Presentation Manager JPEG) UNIX Software: • xli • xv (X Viewer) Source Code: • FBM (Fuzzy Pixmap Manipulation) • GBM (Generalized Bitmap Module) • giftrans • Extended Portable Bitmap Toolkit (pbmlus) • Piclab Source GIF (Graphics Interchange Format) is a creation of CompuServe and is used to store multiple bitmap images in a single file for exchange between platforms and systems. In terms of number of files in existence, GIF is perhaps the most widely used format for storing multibit graphics and image data. Even a quick peek into the graphics file section of most BBSs and file archives seems to prove this true. Many of these are high-quality images of people, landscapes, cars, astrophotographs, and anthropometric gynoidal data (you guess what that is). Shareware libraries and BBSs are filled with megabytes of GIF images. The vast majority of GIF files contain 16-color or 256-color near-photographic quality images. Gray-scale images, such as those produced by scanners, are also commonly stored using GIF, although monochrome graphics, such as clip art and document images, rarely are. Although the bulk of GIF files are found in the Intel-based MS-DOS environment, GIF is not associated with any particular software application. GIF also was not created for any particular software application need, although most software applications that read and write graphical image data, such as paint programs, scanner and video software, and most image file display and conversion programs, usually support GIF. GIF was instead intended to allow the easy interchange and viewing of image data stored on local or remote computer systems. File Organization --------------------- GIF is different from many other common bitmap formats in the sense that it is stream-based. It consists of a series of data packets, called blocks, along with additional protocol information. Because of this arrangement, GIF files must be read as if they are a continuous stream of data. The various blocks and sub-blocks of data defined by GIF may be found almost anywhere within the file. This uncertainty makes it difficult to encapsulate every possible arrangement of GIF data in the form of C structures. There are a number of different data block categories, and each of the various defined blocks falls into one of these categories. In GIF terminology, a Graphics Control Extension block is a type of Graphics Control block, for instance. In like manner, Plain Text Extension blocks and the Local Image Descriptor are types of Graphic Rendering blocks. The bitmap data is an Image Data block. Comment Extension and Application Extension blocks are types of Special Purpose blocks. Blocks, in addition to storing fields of information, can also contain sub-blocks. Each data sub-block begins with a single count byte, which can be in the range of 1 to 255 and indicates the number of data bytes that follow the count byte. Multiple sub-blocks may occur in a contiguous grouping (count byte, data bytes, count byte, data bytes, and so on). A sequence of one or more data sub-blocks is terminated by a count byte with a value of zero. The GIF format is capable of storing bitmap data with pixel depths of 1 to 8 bits. Images are always stored using the RGB color model and palette data. GIF is also capable of storing multiple images per file, but this capability is rarely utilized, and the vast majority of GIF files contain only a single image. Most GIF file viewers do not, in fact, support the display of multiple image GIF files or may display only the first image stored in the file. For these reasons, we recommend not creating applications that rely on multiple images per file, even though the specification allows this. The image data stored in a GIF file is always LZW compressed. See Chapter 9 for a discussion of LZW and other compression methods (and also see the sidebar below). This algorithm reduces strings of identical byte values into a single code word and is capable of reducing the size of typical 8-bit pixel data by 40 percent or more. The ability to store uncompressed data, or data encoded using a different compression algorithm, is not supported in the current version of the GIF format. LZW Is Not Free ------------------- If you are creating or modifying software that implements the LZW algorithm, be aware that under certain circumstances, you will need to pay a licensing fee for the use of LZW. Unisys Corporation owns the patent for the LZW codec (encoding/decoding algorithm) and requires that a licensing fee be paid for each software program that implements the LZW algorithm. Many people have concluded that the Unisys licensing claim applies only to LZW encoders (software that creates LZW data) and not to LZW decoders (software that only reads LZW data). However, Unisys believes that its patent covers the full LZW codec and requires a licensing fee even for software that reads, but does not write, LZW data. For more information about the entire issue of LZW licensing, refer to the section called "LZW Legal Issues" in Chapter 9. For a popular alternative to graphics file formats that use LZW, consider using the Portable Network Graphics (PNG) file format. There are two revisions of the GIF specification, both of which have been widely distributed. The original revision was GIF87a, and many images were created in this format. The current revision, GIF89a, adds several capabilities, including the ability to store text and graphics data in the same file. If you are supporting GIF, you should include support for both the 87a and 89a revisions. It is a mistake to support only the 89a version, because many applications continue to produce only 87a version files for backward compatibility. File Details ---------------- The "GIF87a" section here discusses features common to both versions; the "GIF89a" section describes only the features added in GIF89a. GIF87a ---------- Version 87a is the original GIF format introduced in May 1987 and is read by all major software applications supporting the GIF format. Figure GIF-1 illustrates the basic layout of a GIF87a file. Each file always begins with a Header and a Logical Screen Descriptor. A Global Color Table may optionally appear after the Logical Screen Descriptor. Each of these three sections is always found at the same offset from the start of the file. Each image stored in the file contains a Local Image Descriptor, an optional Local Color Table, and a block of image data. The last field in every GIF file is a Terminator character, which indicates the end of the GIF data stream. Figure GIF-1: GIF87a file layout ______________________________ | missing | |______________________________| Header ---------- The Header is six bytes in size and is used only to identify the file as type GIF. The Logical Screen Descriptor, which may be separate from the actual file header, may be thought of as a second header. We may therefore store the Logical Screen Descriptor information in the same structure as the Header: typedef struct _GifHeader { // Header BYTE Signature[3]; /* Header Signature (always "GIF") */ BYTE Version[3]; /* GIF format version("87a" or "89a") */ // Logical Screen Descriptor WORD ScreenWidth; /* Width of Display Screen in Pixels */ WORD ScreenHeight; /* Height of Display Screen in Pixels */ BYTE Packed; /* Screen and Color Map Information */ BYTE BackgroundColor; /* Background Color Index */ BYTE AspectRatio; /* Pixel Aspect Ratio */ } GIFHEAD; Signature is three bytes in length and contains the characters GIF as an identifier. All GIF files start with these three bytes, and any file that does not should not be read by an application as a GIF image file. Version is also three bytes in length and contains the version of the GIF file. There are currently only two versions of GIF: 87a (the original GIF format) and 89a (the new GIF format). Some GIF87a file viewers may be able to read GIF89a files, although the stored image data may not display correctly. Logical Screen Descriptor The Logical Screen Descriptor contains information describing the screen and color information used to create and display the GIF file image. The ScreenHeight and ScreenWidth fields contain the minimum screen resolution required to display the image data. If the display device is not capable of supporting the specified resolution, some sort of scaling will be necessary to properly display the image. Packed contains the following four subfields of data (bit 0 is the least significant bit, or LSB): Bits 0-2 Size of the Global Color Table Bit 3 Color Table Sort Flag Bits 4-6 Color Resolution Bit 7 Global Color Table Flag The Size of the Global Color Table subfield contains the number of bits in each Global Color Table entry minus one. For example, if an image contains 8 bits per pixel, the value of this field is 7. The total number of elements in the Global Color Table is calculated by shifting the value one to the left by the value in this field: NumberOfGlobalColorTableEntries = (1L << (SizeOfTheGlobalColorTable + 1)); The Size of the Global Color Table subfield is always set to the proper size even if there is no Global Color Table (i.e., the Global Color Table Flag subfield is set to 0). If the Color Table Sort Flag subfield is 1, then the Global Color Table entries are sorted from the most important (most frequently occurring color in the image) to the least important. Sorting the colors in the color table aids an application in choosing the colors to use with display hardware that has fewer available colors than the image data. The Sort flag is only valid under version 89a of GIF. Under version 87a, this field is reserved and is always set to 0. The Color Resolution subfield is set to the number of bits in an entry of the original color palette minus one. This value equates to the maximum size of the original color palette. For example, if an image originally contained eight bits per primary color, the value of this field would be 7. The Global Color Table Flag subfield is set to 1 if a Global Color Table is present in the GIF file, and 0 if one is not. Global Color Table data, if present, always follows the Logical Screen Descriptor header in the GIF file. BackgroundColor in the Logical Screen Descriptor contains an index value into the Global Color Table of the color to use for the border and background of the image. The background is considered to be the area of the screen not covered by the GIF image. If there is no Global Color Table (i.e., the Global Color Table Flag subfield is set to 0), this field is unused and should be ignored. AspectRatio contains the aspect ratio value of the pixels in the image. The aspect ratio is the width of the pixel divided by the height of the pixel. This value is in the range of 1 to 255 and is used in the following calculation: PixelAspectRatio = (AspectRatio + 15) / 64; If this field is 0, then no aspect ratio is specified. Global Color Table ---------------------- The Logical Screen Descriptor may be followed by an optional Global Color Table. This color table, if present, is the color map used to index the pixel color data contained within the image data. If a Global Color Table is not present, each image stored in the GIF file contains a Local Color Table that it uses in place of a Global Color Table. If every image in the GIF file uses its own Local Color Table, then a Global Color Table may not be present in the GIF file. If neither a Global nor a Local Color Table is present, make sure your application supplies a default color table to use. It is suggested that the first entry of a default color table be the color black and the second entry be the color white. Global Color Table data always follows the Logical Screen Descriptor information and varies in size depending upon the number of entries in the table. The Global Color Table is a series of three-byte triples making up the elements of the color table. Each triple contains the red, green, and blue primary color values of each color table element: typedef struct _GifColorTable { BYTE Red; /* Red Color Element */ BYTE Green; /* Green Color Element */ BYTE Blue; /* Blue Color Element */ } GIFCOLORTABLE; The number of entries in the Global Color Table is always a power of two (2, 4, 8, 16, and so on), up to a maximum of 256 entries. The size of the Global Color Table in bytes is calculated by using bits 0, 1, and 2 in the Packed field of the Logical Image Descriptor in the following way: ColorTableSize = 3L * (1L << (SizeOfGlobalColorTable + 1)); The Header, Logical Screen Descriptor, and Global Color Map data are followed by one or more sections of image data. Each image in a GIF file is stored separately, with an Image Descriptor and possibly a Local Color Table. The Image Descriptor is similar to a header and contains information only about the image data that immediately follows it. The Local Color Table contains color information specific only to that image data and may or may not be present. Local Image Descriptor -------------------------- The Local Image Descriptor appears before each section of image data and has the following structure: typedef struct _GifImageDescriptor { BYTE Separator; /* Image Descriptor identifier */ WORD Left; /* X position of image on the display */ WORD Top; /* Y position of image on the display */ WORD Width; /* Width of the image in pixels */ WORD Height; /* Height of the image in pixels */ BYTE Packed; /* Image and Color Table Data Information */ } GIFIMGDESC; Separator contains the value 2Ch and denotes the beginning of the Image Descriptor data block. Left and Top are the coordinates in pixels of the upper-left corner of the image on the logical screen. The upper-left corner of the screen is considered to be coordinates 0,0. Width and Height are the size of the image in pixels. Packed contains the following five subfields of data (bit 0 is the LSB): Bit 0 Local Color Table Flag Bit 1 Interlace Flag Bit 2 Sort Flag Bits 3-4 Reserved Bits 5-7 Size of Local Color Table Entry The Local Color Table Flag subfield is 1 if a Local Color Table is associated with this image. If the value of this subfield is 0, then there is no Local Color Table present, and the Global Color Table data should be used instead. The Interlace Flag subfield is 1 if the image is interlaced and 0 if it is non-interlaced. (See the description of Image Data for an explanation of interlaced image data.) The Sort Flag subfield indicates whether the entries in the color table have been sorted by their order of importance. Importance is usually decided by the frequency of occurrence of the color in the image data. A value of 1 indicates a sorted color table, while a value of 0 indicates a table with unsorted color values. The Sort Flag subfield value is valid only under version 89a of GIF. Under version 87a, this field is reserved and is always set to 0. The Size of Local Color Table Entry subfield is the number of bits per entry in the Local Color Table. If the Local Color Table Flag subfield is set to 0, then this subfield is also set to 0. Local Color Table --------------------- If a Local Color Table is present, it immediately follows the Local Image Descriptor and precedes the image data with which it is associated. The format of all Local Color Tables is identical to that of the Global Color Table. Each element is a series of 3-byte triples containing the red, green, and blue primary color values of each element in the Local Color Table: typedef struct _GifColorTable { BYTE Red; /* Red Color Element */ BYTE Green; /* Green Color Element */ BYTE Blue; /* Blue Color Element */ } GIFCOLORTABLE; The number of entries and the size in bytes of the Local Color Table is calculated in the same way as the Global Color Table: ColorTableSize = 3L * (1L << (SizeOfLocalColorTable + 1)); ColorTableNumberOfEntries = 1L << (SizeOfLocalColorTable + 1); A Local Color Table only affects the image it is associated with and, if it is present, its data supersedes that of the Global Color Table. Each image may have no more than one Local Color Table. Image data -------------- GIF files do not compress well when stored using file archivers such as pkzip and zoo. This is because the image data found in every GIF file is always compressed using the LZW (Lempel-Ziv-Welch) encoding scheme, the same compression algorithm used by most file archivers. (See the sidebar about LZW at the beginning of this article.) Compressing a GIF file is therefore a redundant operation, which rarely results in smaller files and is usually not worth the time and effort involved in the attempt. Normally when LZW-encoded image data is stored in a graphics file format, it is arranged as a continuous stream of data that is read from beginning to end. The GIF format, however, stores encoded image data as a series of data sub-blocks. Each data sub-block begins with a count byte. The value of the count byte may range from 1 to 255 and indicates the number of data bytes in the sub-block. The data blocks immediately follow the count byte. A contiguous group of data blocks is terminated by a byte with a zero value. This may be viewed as either a terminator value or as a sub-block with a count byte value of zero; in either case, it indicates that no data bytes follow. Because GIF files do not contain a contiguous stream of LZW-encoded data, each sub-block must be read and the data sent to an LZW decoder. Most sub-blocks storing image data will be 255 bytes in length, so this is an excellent maximum size to use for the buffer that will hold the encoded image data. Also, the LZW encoding process does not keep track of where each scan line begins and ends. It is therefore likely that one scan line will end and another begin in the middle of a sub-block of image data. The format of the decoded GIF image data is fairly straightforward. Each pixel in a decoded scan line is always one byte in size and contains an index value into either a Global or Local Color Table. Although the structure of the GIF format is quite capable of storing color information directly in the image data (thus bypassing the need for a color table), the GIF specification does not specify this as a possible option. Therefore, even 1-bit image data must use 8-bit index values and a 2-entry color table. GIF image data is always stored by scan line and by pixel. GIF does not have the capability to store image data as planes, so when GIF files are displayed using plane-oriented display adapters, quite a bit of buffering, shifting, and masking of image data must first occur before the GIF image can be displayed. The scan lines making up the GIF bitmap image data are normally stored in consecutive order, starting with the first row and ending with the last. The GIF format also supports an alternate way to store rows of bitmap data in an interlaced order. Interlaced images are stored as alternating rows of bitmap data. If you have ever viewed a GIF file that appeared on the screen as a series of four "wipes" that jumped across the screen as the image was displayed, you were viewing an interlaced GIF file. Figure GIF-2 compares the order of rows stored in an interlaced and non-interlaced format. In the non-interlaced format, the rows of bitmap data are stored starting with the first row and continuing sequentially to the last row. This is the typical storage format for most bitmap file formats. The interlaced format, however, stores the rows out of the normal sequence. All the even rows are stored first and all the odd rows are stored last. We can also see that each successive pass usually encodes more rows than the previous pass. GIF uses a four-pass interlacing scheme. The first pass starts on row 0 and reads every eighth row of bitmap data. The second pass starts on the fourth row and reads every eighth row of data. The third pass starts on the second row and reads every fourth row. The final pass begins on the first row and reads every second row. Using this scheme, all of the rows of bitmap data are read and stored. Figure GIF-2: Arrangement of interlaced and non-interlaced scan lines _________________________ | missing | |_________________________| Why interlace a GIF image? Interlacing might seem to make the reading, writing, and displaying of the image data more difficult, and of course it does. Does this arrangement somehow make the image easier to display on interlaced monitors? The answer lies in one of the original purposes of GIF. GIF was designed as an image communications protocol used for the interactive viewing of online images. A user connected to an information service via a modem could not only download a GIF image, but could also see it appear on his or her display screen as it was being downloaded. If a GIF image were stored in a non-interlaced format, the GIF image would display in a progressive fashion starting at the top of the screen and ending at the bottom. After 50 percent of the download was completed, only the top half of the GIF image would be visible. An interlaced image, however, would display starting with every eighth row, then every fourth row, then every second row, and so on. When the download of an interlaced GIF image was only 50 percent complete, the entire contents of the image could be discerned even though only half the image had been displayed. The viewer's eye and brain would simply fill in the missing half. Interlacing presents a problem when converting a GIF image from one format to another. A scan-line table must be created to write out the scan lines in their proper, non-interlaced order. The following sample code is used to produce a scan-line table of an interlaced image: WORD i, j; WORD RowTable1[16]; WORD RowTable2[16]; WORD ImageHeight = 16; /* 16 lines in the GIF image */ for (i = 0; i < ImageHeight; i++) /* Initialize source array*/ RowTable1[i] = i; j = 0; for (i = 0; i < ImageHeight; i += 8, j++) /* Interlace Pass 1 */ RowTable2[i] = RowTable1[j]; for (i = 4; i < ImageHeight; i += 8, j++) /* Interlace Pass 2 */ RowTable2[i] = RowTable1[j]; for (i = 2; i < ImageHeight; i += 4, j++) /* Interlace Pass 3 */ RowTable2[i] = RowTable1[j]; for (i = 1; i < ImageHeight; i += 2, j++) /* Interlace Pass 4 */ RowTable2[i] = RowTable1[j]; The array RowTable1[] contains the mapping of the scan lines in a non-interlaced image, which in this example are the values 0 to 15 in consecutive order. The array RowTable2[] is then initialized by the interlacing code to contain the mapping of the scan lines of the interlaced image: RowTable1[] RowTable2[] 0 0 1 8 2 4 3 9 4 2 5 10 6 5 7 11 8 1 9 12 10 6 11 13 12 3 13 14 14 7 15 15 We can restore the non-interlaced image by stepping through the values stored in RowTable2[]. The 0th row of the non-interlaced image is the 0th row of the interlaced image. The first row of the non-interlaced image is the eighth row of the interlaced image. The second row of the non-interlaced image is the fourth row of the interlaced image, and so on. Trailer ----------- The Trailer is a single byte of data that occurs as the last character in the file. This byte value is always 3Bh and indicates the end of the GIF data stream. A trailer must appear in every GIF file. GIF89a ---------- Version 89a is the most recent revision of the GIF image file format and was introduced in July of 1989. Although the GIF89a format is very similar to GIF 87a, it contains several additional blocks of information not defined in the 87a specification. For this reason GIF89a image files may not be read and displayed properly by applications that read only GIF87a image files. Many of these programs do not not attempt to display an 89a image file, because the version number "89a" will not be recognized. Although changing the version number from "89a" to "87a" will solve this problem, the GIF image data may still not display properly, for reasons we shall soon see. Figure GIF-3 illustrates the basic layout of a GIF89a image file. Just as with version 87a, the 89a version also begins with a Header, a Logical Screen Descriptor, and an optional Global Color Table. Each image also contains a Local Image Descriptor, an optional Local Color Table, and a block of image data. The trailer in every GIF89a file contains the same values found in 87a files. Version 89a added a new feature to the GIF format called Control Extensions. These extensions to the GIF87a format are specialized blocks of information used to control the rendering of the graphical data stored within a GIF image file. The design of GIF87a only allowed the display of images one at a time in a "slide show" fashion. Through the interpretation and use of Control Extension data, GIF89a allows both textual and bitmap-based graphical data to be displayed, overlaid, and deleted as in an animated multimedia presentation. The four Control Extensions introduced by GIF89a are the Graphics Control Extension, the Plain Text Extension, the Comment Extension, and the Application Extension, summarized here and described in greater detail in the sections below. Graphics Control Extension blocks control how the bitmap or plain-text data found in a Graphics Rendering block is displayed. Such control information includes whether the graphic is to be overlaid in a transparent or opaque fashion over another graphic, whether the graphic is to be restored or deleted, and whether user input is expected before continuing with the display of the GIF file data. Plain Text Extension blocks allow the mixing of plain-text ASCII graphics with bitmapped image data. Many GIF images contain human-readable text that is actually part of the bitmap data itself. Using the Plain Text Extension, captions that are not actually part of the bitmapped image may be overlaid onto the image. This can be invaluable when it is necessary to display textual data over an image, but it is inconvenient to alter the bitmap to include this information. It is even possible to construct an 89a file that contains only plain-text data and no bitmap image data at all.

Not necessarily. One of the first truecolor algorithms we implement will be one that continuously interpolates colors between the escape-time bands. A 256-color palette editor will still be useful for designing the colors of such an image. But basically you are right. Truecolor demands a whole different approach to coloring fractals. If truecolor is calculated "on the fly" you won't be able to recolor fractals as a post-process, at least not in the same way. On the other hand, Fractint could simultaneously store the iteration and orbit information in a file, and special post-processing could construct colors using different algorithms, includoing use of a super-long palette. > Isn't this rather a problem in the windows 3.1 and win95 > environment. You won't be able to color cycle if Windows is in a truecolor mode. Bert Tyler did get color cycling to work with the now-very-old Winfract port, but under a 256-color video mode. > Does this mean that Fractint will > primarily remain a dos program or at least non-windows? It means that if you want color cycling, you will have to use a 256-color video driver for windows. In the long run, my opinion is that color cycling will be less and less important as truecolor hardware and software become dominant. Fractint can't stay as a DOS program and progress. At the very least, fractint needs porting to a DOS extender environment such as the djgpp compiler.

Feel free to propose a syntax for embedding Lsystems and IFS into PAR files. But you'll have to make a case for it, and show that there's an advaqntage. The current lsystems and IFS formats make interoperability easy with other programs. For example, fdesign can read and write Fractint IFS files. The lsystem format is pretty standard, we've just wrapped curly brackets around it.

There is a subroutine, RGBMAP, which produces a new .TGA file containing color data instead of iterations data. 2) There seems to be a problem reading in the header which looks like this: Who-knows-what... 12 bytes xdots............ 2 bytes ydots............ 2 bytes Who-knows-what... 2 bytes Max_iteration.... 4 bytes All these values are being read correctly except for ydots, which always ends up being a large number, like 6147489 or such... 3) If you set a viewwindow size of 50x38 and create iterates.tga, then not only is the ydots in the header corrupt, but the actual iteration data is also incorrect. Can someone provide me with the supposed binary file format for the iterates.tga file? Other suggestions welcome... I have another question, but I'll post it in a separate email. Thanks, all!

I mean _unpersoned_ zooming... There is a program out there called Fractal eXtreme which has such a feature, and that program is available for a free trial period (anyone have a URL for that site?) Anyway, I'm debating whether to write my program to work with GIF files or the .TGA file created when you give Fractint the "truecolor=yes" command. The .TGA file would be the easiest to work with, since what I'm really interested in is the iterations value for each pixel, and that's exactly what's in ITERATES.TGA. On the other hand, it seems that the state of Fractint's truecolor support scene is, if not currently, then soon to be undergoing some modifications, whereas the GIF file format seems pretty well established. Also, there may be some problems with Fractint's ability to write ITERATES.TGA for viewwindowed images. Going with the GIF file, on the other hand, would be a pain... mostly because a) there's the LZW compression to deal with, and b) I'm just a novice programmer, and not even any kind of /graphics/ programmer! Choosing to work with GIFs will complicate things programming-wise, but is more likely to mean that my program will still work fine with future versions of Fractint. I'm hoping that Tim will be able to help me come to a decision when he returns... in the meantime, any ideas from the peanut gallery would be most welcome!

Third, the maxiter need be nowhere as high as you had set it -- I set it to 255. Fourth, the Log Palette should be turned on, which I did. The result is visible in the par file named answer.par, which I have attached. I think this is the effect you were after. Hope I was of help, and good luck with those fractals.

Hi Alice, In the simples case with logpallete = -1 or 1 the colours get spread out across the whole range of iterations possible, from 1 ... maxiter. This means that, if you're looking at a zoomed fractal, some of the 256 available colour bands are in effect outside your screen, not displayed and therefore wasted. In extreme cases this would mean only showing a just few colours when you could have 256.. not necessarily a bad thing but often resulting in a picture with little detail. To counter this you can give logpalette a value (say 33 ) which results in the colour bands being spread across iteration values 33 ... maxiter. What autolog does is do the calculations for all the pixels round the edge of your zoomed view first, find out the lowest value it encountered and then use this as the lower end of the colour spread used by logmap. This only gives good results if the fractal is one which has no 'islands' of lower iterations inside such as the Mset. Though this is the most 'efficient' way of using colours it also results in the colourmap being shifted so you might need to cycle things a bit to get back to the look you had before. Hope this helps, Robin.

OK, I'll take a stab at it. Let me know if I obfuscate... ;-) Your average garden-variety fractal takes each screen point and maps it to a complex number, running that number through the same equation over and over again to see what happens. Points "outside" the set head off towards infinity (they get bigger than the "bailout" value) and points "inside" the set don't--they just kind of hang around. Eventually you've run the point through so many iterations you "give up"--this is the maximum iterations value. The problem (as far as speed is concerned) is that all of your inside points are run through your equation the *full* number of times. If there was a way to detect early on that a point isn't going to head to infinity, you could quit early, safe in the knowledge that the point is "inside". Well, for some points, you *can* find out early. Some points, as they are pushed through the equation over and over, produce a repeating cycle of numbers. For example, in the Mandelbrot set, the point at (-2,0), as it is run through the iterated equation z = z*z + c, produces the sequence (0,0), (-2,0). One number produces the other. Obviously that's not heading towards infinity, so if that can be detected, the program can quit early and not calculate 10,000 iterations of that point. To see what's going on, start FractInt and let the M-set fully draw. Press "O" (to turn on the Orbits window) and "L" (to connect all the points with Lines). Now move the pointer over the M-set. What FractInt is showing you is how the point you start at moves around as it is run through the iterative equation. Move the pointer into the main bud at the left side, and you'll see the point ping-pongs between two areas. Now move the pointer into the big bud at the top. You'll see a rough triangle, as the point moves through three small areas that make up the triangle corners. (Press L again to see the point clusters.) For many fractal types, inside points show this kind of periodic (cyclic) behavior. But here's the catch: some points may *look* like they're doing this, but in fact the numbers are just a little bit different each time; and if you iterate long enough, they suddenly become unstable and shoot off towards infinity. With FractInt's periodicity checking, sometimes these points are mistaken early on as periodic points, when in fact they just need to be iterated more to show that they shoot off to infinity. To see an example of this, I've attached a PAR file of a Julia set. If you generate this as is, you'll see the middle of the looping spiral is missing, even though the maximum iterations is set to 1000 and it should appear. (And it uses two-pass rendering, so it's not being dropped out by guessing.) If you press "G" and type "periodicity=no" to turn off periodicity checking, the fractal will redraw and you'll see the inner loops of the spiral. The effect is much more pronounced at lower resolutions (like 640x480) than my normal working res of 1024x768. This type of drop-out can be baffling if you forget to try turning off periodicity checking. --=====================_872111269==_ Content-Type: text/plain; charset="us-ascii" Content-Disposition: attachment; filename="Period.par" periodicityexample { reset=1960 type=julia passes=2 center-mag=0/0/0.6666667 params=-0.7482893185793418/-0.025423566101695 float=y maxiter=1000 bailout=128 inside=0 colors=@atomic.map } --=====================_872111269==_ Content-Type: text/plain; charset="us-ascii" Damien M.

Jones" Subject: Re: (fractint) 2nd Question: New Hole Date: 20 Aug 1997 19:33:46 -0400 Alice, This one took me a while, but it is a bailout problem. The fractal type you're using in this image is a Newton-type, which uses a different bailout test than some fractals. With a Newton-type, you test to see if your iterated value homes in on a "solution", rather than if it heads to infinity. So typically you check to see if a value gets very small, instead of gets very big. In this case, the bailout is at the end of the function, and is .0001--change it to .0000001 and your hold will close right up. BTW, this was one of my favorite images of yours. Very interesting. Here's the corrected FRM (just paste this in your own FRM file): newCGNewtonSinExp (XAXIS) { z=pixel: z1=exp(z) z2=sin(z)+z1-z z=z-p1*z2/(cos(z)+z1) .0000001 < |z2| } Better yet, replace .0000001 with p3, and you can adjust the bailout to taste. Just remember that in Newton types, a *smaller* bailout means points iterate longer; with other types (where points shoot off to infinity), *larger* bailouts means points iterate longer.

For example, I want to color a point inside an MSet component according to its period or some other function of its position, c.

Date: 21 Aug 1997 05:08:53 GMT From: "Phong" Organization:Coteric Continuum Newsgroups: sci.fractals I'm trying to write a formula that will bail out the normal way for some pixels, but will specify a specific color for ones that meet a certain criteria at some point during their iteration. Basically what I am trying to do is the exact same thing as the parameter inside=epsiloncross, except I want to specify how close the orbits must come to the axes (or some arbitrary points or lines in the complex plane) to bail out (and get colored a specific color rather than the iteration count). Right now, I'm keeping track of what iteration I'm currently on, and if I want to bail out to a certain color, I set a variable then bail out when the color wraps around to the right one. That is a total kludge, slows things down and is awkward. Is there a better way? If not, is it something that is planed for a future version of Fractint (i.e. a variable you can set to specify that a pixel should be a certain color rather than the number of iterations). -- Tom Schumm ---- http://www.ismi.net/~phong/ ----__/\__---- Phong -- -- v3.1 GCS/M d- s: a20 C$++>++++ W++(--) P++++ M-- \ / w---(++) -- -- UBLS$+++(++++) L+ t+* X+ b+ DI++++ G+ !r y? __/\__/ \__/\__ e -- -- the Coteric Continuum -- O- -- phong@ismi.net / tgschumm@mtu.edu -- Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Tim Wegner" Subject: Re: (fractint) Tru.c workings Date: 21 Aug 1997 18:57:04 -0600 > Date: Mon, 18 Aug 1997 08:20:48 -0600 (MDT) > From: Jason Hine > To: fractint@xmission.com > Subject: (fractint) Tru.c workings > Reply-to: fractint@mail.xmission.com > Howdy all, > After a weekend of playing around with the little piece of C code that > comes with Fractint called TRU.C, I've determined the following (maybe!): > > 1) TRU.C is designed to read in the file ITERATES.TGA produced when > Fractint is given the "truecolor=yes" command; TRU.C first reads in the file > header (see next note!), then reads in the actual iterations data.

Jones" Subject: (fractint) New Coloring Methods Date: 22 Aug 1997 00:32:43 -0400 Hello all, In my first post to this list, I asked if anyone knew how to add new coloring options to FractInt, preferably using the formula parser (instead of recompiling the C code). Now I see some others are asking the same thing. I've done some playing around, and I found out how to do it. Let me give a little background, first. I've often wondered what the bof60 inside coloring option would look like applied to outside points. I got my first taste by fudging the distance estimator method (DEM) pixel percentage value. If you turn DEM on, you can set a percentage distance (relative to a pixel's size) such that if the point is within that distance to the set's inside, it is colored as an inside point, even though the point is outside. Well, I set this to a ridiculous number (32767) and suddenly *all* my points are colored like inside points. This produces some pretty neat pictures, and I've been moderately happy with the results. Except for three things. First, most of the inside coloring options aren't very tweakable. Second, because I'm relying on points being within 327 pixels of the set, sometimes I get points that don't quite reach, and get colored using the outside coloring method--and that really screws up poster-size prints. And third, it still only gives me a few more coloring options, only a couple of which (bof60 and bof61) produced really good results. So I thought of a way to use the formula parser to add new coloring techniques. Now, I'm sure some of you old hands and formula-writing already knew this trick, but it was quite a discovery for me. The basic trick is that just before you bail out, you figure out what your color should be, and make it your z value's real part. Then you can use FractInt's "real" coloring option to extract the color value. Of course, since the "real" coloring option adds in the iteration count too, you track that and subtract it out of the z value's real part; this cancels it out. What you're left with is a whole new avenue of coloring fractals. So, my original goal was implemented like this: Color01 { ; New coloring technique #1 (bof60 outside) ; outside = real: closest approach to p1 ; p2: color scaling factor ; p3: bailout z = 0, c = pixel, closest = 100000, point = 0, done = 2: z = fn1(z) + c done = done + 1 IF (|z-p1| < closest) point = z closest = |z-p1| ENDIF IF (|z| > p3) point = point - p1 z = |point| * p2 - done done = -1 ENDIF done >= 0 } The formula remembers the orbit point closest to p1 (so it doesn't have to be 0,0) and allows you to specify a color scaling factor and a bailout. (Set fn1 to the sqr function to get the M-set.) The color scaling factor is important; it lets you tweak the colors as you zoom in. And because the images don't rely on the distance estimator method to fake out the coloring routine, they're totally resolution-independent, and can be generated poster-size. The above formula only colors outside pixels. I wanted to be able to color inside pixels at the same time (as an option). Doing that is pretty easy--you just bail out one iteration early, so FractInt never thinks you've quite made it to an inside point: Color01i { ; New coloring technique #1i - same as #1, does inside too ; might want to turn off periodicity checking ; outside = real: closest approach to p1 ; p2: color scaling factor ; p3: bailout z = 0, c = pixel, closest = 100000, point = 0, done = 2: z = fn1(z) + c done = done + 1 IF (|z-p1| < closest) point = z closest = |z-p1| ENDIF IF (|z| > p3 || done >= maxit) z = |point-p1| * p2 - done done = -1 ENDIF done >= 0 } It's important to remember to turn off periodicity checking--since this formula basically fools FractInt into thinking all pixels are "outside", if you leave periodicity on, it might end up thinking some points are "inside" and not color them the way you want. bof60 colors based on the distance of closest approach to the origin. bof61 colors based on the iteration of closest approach to the origin. In one picture I generated, I wanted to plot the *angle* of closest approach to the origin. This was several months ago, before I had figured out this new trick, so I wrote a program to do the job. But this week I wrote a FRM to do the trick: Color05 { ; New coloring technique #5 (angle of closest approach) ; might want to turn off periodicity checking ; outside = decomp: angle of closest approach to p1 ; p2: bailout z = 0, c = pixel, closest = 100000, point = 0, done = 2: z = fn1(z) + c done = done + 1 IF (|z-p1| < closest) point = z closest = |z-p1| ENDIF IF (|z| > p2) z = point-p1 done = -1 ENDIF done >= 0 } Since writing angle-decoding formula stuff is obnoxious, I thought to take advantage of FractInt's decomposition option--which takes the final z value and colors based on its angle. So the above formula remembers the actual point of closest approach, and just before bailing out, resets z to this value--which FractInt then considers the "last value" and colors based on its angle. I have an inside variant of this, too: Color05i { ; New coloring technique #5 (angle of closest approach) ; might want to turn off periodicity checking ; outside = decomp: angle of closest approach to p1 ; p2: bailout z = 0, c = pixel, closest = 100000, point = 0, done = 2: z = fn1(z) + c done = done + 1 IF (|z-p1| < closest) point = z closest = |z-p1| ENDIF IF (|z| > p2 || done >= maxit) z = point-p1 done = -1 ENDIF done >= 0 } And here's a PAR that produces an effect similar to what I had to write a program for earlier: mandelc { reset=1960 type=formula formulafile=dmj.frm formulaname=Color05i function=sqr center-mag=-0.938416/0/0.6666667 params=0/0/4/0 float=y maxiter=256 inside=0 invert=0.5/-0.5/0 decomp=256 periodicity=0 colors=@bluegrey.map } I am still playing with this technique, and so far I've used it to produce some moderately spectacular images. I'll post some in my gallery soon. Some of the coloring techniques I'm using require one-pass rendering to work properly, so it's faster to download them than to generate them. Damien M.

Also please take = in consideration that english is not my native language and I am to lazy to get the dictionary. At the age of 12 I was drawing my first fractal, a Pythagoras-tree (some = of you might remember that in the old days drawing was a proces done by = people on flat white stuff called paper with a little stick called a pencil or pen). This tree had 1023 branches so you can understand it was a hell of a job. I used ink so one tiny mistake would spoil the whole image, and that is why I never managed to finish it. In those days the only computer I had ever seen was in a comic-book (no, I was born AFTER the war), but I already thought how wonderful it would be = if I had a machine that would be able to do the drawing. Seven years later I had my first computer, a Sinclair ZX81 with a RAM-memory of - hold your breath - 16 Kbyte (born after WHICH war?). The graphic screen was = something like 80 x 46 x 2, I am not sure, but it wasn=A2t much more. I could even = save my BASIC-programs on a tape=21 But I never came to make this machine draw = a pythagoras-tree for me. I had read an article about Mandelbrot fractals in some magazine at the library, and I thought: this is very exiting and I want to learn all about it=21 When I had access to a proper computer for the first time, and = learned some TurboPascal, I started making my own fractal-drawing program. The program was very slow, and I had only a four color CGA-screen available, but I managed to zoom in on the Mandelbrot-set. I also started thinking about how to build features like Fractint has now, something like solid-guessing and periodicity-checking. But I am not exactly a programming engineer and I realised this was going to be very complicated.= =20 And then one day... a friend of mine gave me a present for my birthday. It was floppy-disc with a copy of Fractint 17.2 for DOS. Yes, it was a cheap present because the program is freeware and even the disc was used, but until this day I am very grateful to him. In the mean time I had bought a 80286-computer and the machine must have calculated thousands of fractals by now. I wouldn=A2t have been surprised if one day the poor thing would = have put a message on its screen like =A1Are you nuts??? at the moment when I feeded him another 200 line batch-file. I have also spend many hours editing color maps to get good looking images, and I must say I managed to get some real nice ones. A few weeks ago I bought a new computer with a Pentium 166 MHz processor. It was a terrible shock to see how fast Fractint runs on this. I had a fractal that took more than 11 hours to compute on my old 80286, on the Pentium it only took 10 minutes......and there are still people complaining= that Fractint is SLOW???=21=21? My next plan is to buy a colour printer and put some of my images on that old fashioned flat white stuff. I am also planning to get an Internet-account at home and maybe put a gallery on a homepage.

I should know better to write technical messages just before going to bed; I leave things out that are important. :-) For those who tried the FRMs and found they generated a blank screen, switch to floating-point math. Also don't forget to set a bailout; the default is zero, and the FRM doesn't substitute a different value if you forget to put one in. 4 is good to start, but depending on the point you've selected for p1, you might want to use something higher to prevent discontinuities. And if you don't set the color scaling factor (for the color01 formula) to something besides 0, you won't see the new coloring method. As for the PAR... well, boneheaded me didn't realize until after I posted it that it referred to a map file rather than include the colors directly. Color me stupid.

If there are any predefined constants that you would like added to the parser to facilitate coloring methods, let me know and I'll add them. A predefined constant is a variable that the parser assigns a particular value to. "Constant" isn't exactly the right term; maybe I should call them "automatically updated variables" or some such. The whitesq variable used in pseudohighcolor is an example. Also, when you have arrives at a few good formula examples of coloring methods, we can add them to fractint.frm.

Jones" Subject: (fractint) More fun with new coloring Date: 22 Aug 1997 23:06:48 -0400 Howdy folks, Here's another new coloring method picture. The basic idea with this one is to position a ring somewhere on the complex plane, and track the closest any iteration value gets to it; color based on the angle of the closest point. Using a ring instead of a point produces some really wild effects; playing with the ring's location and diameter gives this lots of variety. Good palettes help enormously, of course. When I wrote this formula, I erred and computed the distance incorrectly--the square root should be taken before the subtracting the ring's diameter. So mathematically it's wrong... but it still produces some really cool pictures, like this one. So aesthetically, it's fine. :-) This image took a while to render, mainly because I was generating it at such high resolution, but also because it doesn't work with guessing (hence the two-pass rendering). I prefer to render high, then reduce image size in a graphics program to anti-alias the results. On my Cyrix 6x86P120+ it took 4:01.72 to render at 640x480; the one I keep in my collection is a 1600x1200 I rendered on a PPro-200 (which still took over fifteen minutes). -----8<----- Begin FractInt 19.6 PAR file RubySlippers { ; Copyright 1997 Damien M.

If the bailout is set above 4, odd things happen to the iteration bands. I have attached two PARs, one with the bug and one without. The only difference between the two is the bailout value. I'd like someone else to be able to verify this. It occurs on both a PPro and a 6x86, so it's not a processor-related thing.

I think it can be done, especially in conjunction with - iterates.tga. The biggest problem is that you need access to the last z value for the no-stepping algorithm, and you really need more than 256 colors to do a good job. Still, if you don't mind the 256-color limit, you can make the entire color palette repeat at an arbitrary number of iterations--instead of looping at 255, you could make it loop at 253, or 127.5... whatever you want.

A predefined constant is a variable that the parser assigns a - particular value to. "Constant" isn't exactly the right term; maybe I - should call them "automatically updated variables" or some such. The - whitesq variable used in pseudohighcolor is an example. I'll have to think about that. This is an interesting idea. The ismand keyword will be most valuable, though, and is the best idea I've heard for the formula parser in a long time. One thing I'd definitely like, though: more parameters! Three is pretty limiting. This is probably more an interface issue than anything else, though. BTW, as long as I'm thinking about it, does the formula parser to any sort of JIT compiling? (Yes, I could look at the source code, but it's easier to ask you than to unzip it and hunt for the relevant portions. :-) - Also, when you have arrives at a few good formula examples of - coloring methods, we can add them to fractint.frm.

Which I have been reading since (its about 900 pages long). It is definitely a book to beg, buy or steal; I cannot express how good it is. Now for an unrelated newbie question: I have been creating slews of little fractal planets using Fractint's spherical projection routine. And I should like to make them spin. Can anyone possibly point me in the right direction towards animating these things? I apologize in advance if this is something I should be able to figure out without help. I also noticed people have been introducing themselves in various ways. I live in Washington, D.C., don't work for the feds, live with Molly (who thinks Fractint is the greatest program she's ever seen), and have been enjoying Fractint myself for about a year. I do not think I could bear working in offices without it; the .zip file very conveniently fits onto one floppy.

I always run fractint by accessing the dos prompt in WIN95. I have now had to reformat my HD and reinstall windows 95 twice as the dos prompt window disapears and turns into one screen window. It is worth it so I can use the fractint software with my faster computer but perhaps I should run in dos mode on bootup? I believe this question is in more than Yehudas and my minds because as users of WIN95 we have grown to expect these kind of mishaps when using software not written for out operating system and a touchy one at best. I would like to introduce myself. My name is Jimmy Emerson and I have been using fractint for 7 years. I started with my first $3500 8 MHz 286. I am importing the images into Corel 7 for landscapes and I use them as textures in some places in CorelDream and on CAD objects imported into CorelDraw. I love the software but wish there was a howto manual on it that told you such things as "hold down mouse button and move forward and backward when in the palette editing mode while on one of the color tiles". This is an example of the mechanics of fractint that I can find no documentation for. (BTW, I just finished differential equations, placing four semesters of Calculus under my belt...at 39 years old I'm proud of this acomplishment) Who said you can't teach an old dog new tricks?

Right now, whenever the user switches fractal types, the parametersm, colors, and location are reset. If an option could be included to switch types, but leave all other settings intact, this would make it easy to explore using the fast mandel type, then switch to one of these other more exotic coloring options once an interesting location is found. I suggest using CTRL-T as the key to invoke this function, and that from there it act pretty much like pressing T normally would. Just a thought. Damien M.

Jones" Subject: (fractint) New coloring methods (need help) Date: 24 Aug 1997 21:07:47 -0400 I need some help. I have been trying to use the new coloring method trick to write an "absolute decomposition" method. But it doesn't seem to be working right, and the problem seems to be the mathematics. So those of you with some understanding of fractal mathematics, please help this college-math-dropout out. :) The decomposition provided by FractInt's decomp option takes the last value of z and turns its angle into a color. Settings decomp=256 will map the entire palette to the full range of angles. However, because this is done on the *last* iteration, the number of times the palette loops within an iteration band doubles with each iteration band. What I'd like to do is have a decomposition that doesn't do this--so that color transitions coincide with field lines around the M-set. In the book, _Chaos and Fractals: New Frontiers of Science_, by Peitgen, Juergens, and Saupe, pp. 851-852, the authors describe how this can be done. Basically, they suggest that the sign of the imaginary component of each z[n] term forms a sequence of binary digits which can simply be read off as the field line; as more iterations are performed, more binary digits are added that simply refine the angle further. This sounded ideal, so I cooked up this FRM: -----8<----- Start FRM file Color12 { ; New coloring technique #12 (absolute decomposition) ; outside = real: absolute decomposition ; p1r: decomposition color scaling (start with 256) ; p2r: bailout (start with 128) IF (real(p1) == 0) p1 = 256 ENDIF IF (real(p2) == 0) p2 = 128 ENDIF z = 0, c = pixel, done = 2, d = 0, dinc = 0.5: z = sqr(z) + c done = done + 1 IF (imag(z) < 0) d = d + dinc ENDIF dinc = dinc * 0.5 IF (|z| > real(p2)) z = d * real(p1) - done done = -1 ENDIF done >= 0 } -----8<----- End FRM file The problem is, this doesn't work. I get strange discontinuities when I try it. I tried this a while back with a custom program, and got the same results; thinking it was just a bug in my program that I didn't have time to fix, I filed it away for future tinkering. That the above formula does the same thing in FractInt seems to imply there is something wrong with the underlying math. Yet the book has pictures which show the correct result, so obviously the authors were able to make the technique work. I can produce their image on p. 854, but only if I use the last bit. The last bit seems to be the only that is accurate, and lines up correctly. I was able to "fudge" the results I wanted by taking the decomposition at a fixed iteration (i.e. always use the 32nd iteration) but this doesn't seem to work very well upon zooming in. The reason I want this feature is because if it is combined with the "continuous color" method posted earlier, it can be used to give FractInt the spiraling-gradient capabilities of KPT Fractal Explorer. To date I have seen nothing with this capability besides the KPT plug-in for Photoshop. Any help would be appreciated. Damien M.

Jones" Subject: (fractint) New coloring methods (again) Date: 24 Aug 1997 21:07:44 -0400 I'm back... :-) Ron Barnett suggested using Linas Vepstas' no-banding coloring technique with the techniques I suggested earlier this week. While my first response was that it would not be possible to do true-color coloring with the technique, I think that may have been a bit hasty. Below is a FRM that implements Linas' coloring technique in FractInt. The color scaling value is used to tweak how "rapidly" colors cycle through the entire palette. Using a value of 1 (the default) will give you the default integer iteration bands. Using a value of 255 would cause the entire palette to cycle through once for each integer band (*rapid* color change). Values between zero and one would spread color changes out over several iterations, useful for zoomed-in areas. FractInt is still a 256-color program, so it's not possible to directly render true-color images as suggested. Using ITERATES.TGA isn't in itself a solution, since this only stores the integer part of the iteration count (and no coloring method changes that). You don't get the exit value of z, which is needed for the true-color rendering. However, some creative soul could take the ITERATES.TGA as the base iteration count, then generate the same point with the formula below, using a color scaling factor of 255--this would give you the fractional iteration, in 1/255ths. Combine the two, and you have a fairly accurate representation of fractional iteration value--which would then be mapped to an arbitrary color gradient. (You have to use 255 instead of 256 because FractInt wraps the real outside coloring option from 255 to 1, not zero.) Anyway, even if you don't want to use the formula below for that purpose, it can be used to prepare multiple layers for combination in a graphics program. (For example, generate one image in shades of grey, another in colors, but with a different color scale... multiply the two together in Photoshop. Ooooo, pretty. :) Now that I think about it, PHC techniques could be used to apply two different color scales to the same image. The PHC version follows the original "continuous color" version below. -----8<----- Start FRM file Color13(XAXIS) { ; New coloring technique #13 (continuous color) ; outside = real: continuous color ; p1r: color scaling (0 means default of 1--normal iteration bands) ; p2r: bailout (0 means default of 128) IF (real(p1) == 0) p1 = 1 ENDIF IF (real(p2) == 0) p2 = 128 ENDIF z = pixel, c = pixel, done = 0, il2 = 1/log(2.0), lp = log(log(real(p2))): z2 = sqr(z) z = z2 + c done = done + 1 IF (|z| > real(p2)) z = (done + 2*il2*lp - il2*log(log(cabs(z)))) * real(p1) - done done = -1 ENDIF done >= 0 } Color13phc { ; New coloring technique #13 (continuous color, PHC) ; outside = real: continuous color ; p1r: color scaling 1 (0 means default of 1--normal iteration bands) ; p1i: color scaling 2 (0 means default of 1--normal iteration bands) ; p2r: bailout (0 means default of 128) IF (real(p1) == 0) p1 = 1 + imag(p1) ENDIF IF (imag(p1) == 0) p1 = real(p1) + (0,1) ENDIF IF (real(p2) == 0) p2 = 128 ENDIF z = pixel, c = pixel, done = 0, il2 = 1/log(2.0), lp = log(log(real(p2))): z2 = sqr(z) z = z2 + c done = done + 1 IF (|z| > real(p2)) IF (whitesq) z = (done + 2*il2*lp - il2*log(log(cabs(z)))) * real(p1) - done ELSE z = (done + 2*il2*lp - il2*log(log(cabs(z)))) * imag(p1) - done ENDIF done = -1 ENDIF done >= 0 } -----8<----- End FRM file -----8<----- Start PAR file ccphc { ; Continuous Color PHC example reset=1960 type=formula formulafile=dmj.frm formulaname=color13phc passes=1 center-mag=-0.15519576843965720/+0.64963388054984320/6158.933/1/-49.999 params=16/0.2/0/0 float=y maxiter=50000 inside=0 outside=real colors=000mry<7>rkk<15>NG0<3>0F0<5>040<8>0bN<13>zzz<114>C11B00B00A00086<\ 77>mrz } -----8<----- End PAR file Damien M.

I have now had to reformat my HD and reinstall windows 95 twice as the dos prompt window disapears and turns into one screen window.<< If, by a "one screen window", you mean maximised then this is normal. I have run different DOS realease versions of Fractint under Win 95 on a 486DX2 and, more recently, on a Pentium II without difficulty. It is important that you set up a shortcut (or PIF) to ensure that Windows 95 i= s told to run Fractint maximised and NOT in a window. To do this - (1) open explorer and locate your Fractint directory, then *right-click* = on "FRACTINT.EXE" (2) select "properties" from the list of options (3) on the "fractint.exe properties" box click on the "Program" tab (4) from the pull-down list next to "Run", choose "Maximized" (5) check the "Close on exit" box (6) click on the "Screen" tab (7) choose the "Full-screen" button in the "Usage" section (8) click on "OK" After this a new file will appear in your fractint directory called "fractint" (no extension), this will be appear with the description "shortcut to MS-DOS program". Right clicking will reveal it's MS-DOS name= to be "fractint.pif" If you prefer to run your DOS prompt in a window and you find programs li= ke Fractint re-set it to full screen, then just follow the reverse of the above to restore it to "normal" i.e. right-click your MS-DOS prompt and choose "properties" on the "Program" tab choose "normal window" on the "Screen" tab choose "window" Your DOS "window" will then re-appear! Once you have set up the shortcut for Fractint it won't mess with you DOS= prompt settings any more. But, better still, why not create a shortcut to= Fractint in one of your program groups, or have its icon sitting right there on you desk-top and give the DOS prompt a miss all together? I hope these suggestions help your operating system and Fractint to live= in harmony cheers, Les St Clair Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Rich Thomson Subject: Re: (fractint) New Coloring Methods Date: 25 Aug 1997 10:39:05 -0600 In article <970822205207_17241903@emout12.mail.aol.com> , RBarn0001@aol.com writes: > << Also, when you have arrives at a few good formula examples of > coloring methods, we can add them to fractint.frm. >> > > Tim, when I get back from vacation, I going to explore whether some of > Damien's ideas can be used to implement the Linas Vepstas true coloring > algorithm. I think it can be done, especially in conjunction with > iterates.tga. Hmm... I was thinking that when truecolor support is added, that you would simply write a formula saying how the pixel would be colored. We have formulas for complex numbers (two components), but formulas involving colors have to carry around three components (perhaps even four if you allow alpha channel support). Colors also have a color space associated with them. RGB and HSV are useful colorspaces and you might want to add support for others. Here's a stab at some intrinsic functions that would be useful in writing color formulas: colormap(x) Does colormap lookup for index x. If x has a fraction, then interpolate between floor(x) and ceil(x). Lookup is done modulo the colormap length. rgb(r, g, b) Specify an RGB color, r/g/b in 0-1 range rgba(r, g, b, a) Specify an RGB color with alpha coverage hsv(h, s, v) Specify an HSV color, hue in 0-360 range (or 0-2Pi), s/v in 0-1 range. hsva(h, s, v, a) Specify an HSV color with alpha coverage interpolate(c1, c2, t) Interpolate between c1 and c2 by t: t*c1 + (1-t)*c2 When 24-bit support is finally added please don't overlook the alpha channel (32-bit support). Many cards can support 32-bit pixels in the frame buffer and PNG can support transparency by having an alpha channel. I have gotten many wonderful effects from the M-set by using the alpha channel keyed to the iteration somehow. This is a powerful feature and being able to write a formula to describe the coloring will make it very handy. I suppose one would write two formulas, one for "inside" coloring and another for "outside" coloring. I'd like to see the inside/outside options made available somehow in the color formula. For instance, the decomposition options should be easy to write in the color formulas. -- ``Between stimulus and response is the will to choose.'' -- Steven Covey =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 3D Paint: The Power to Create in 3D; Rich Thomson email me for more info rthomson@ptc.com Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: Bob Norton Subject: (fractint) Matrox Millenium cards Date: 25 Aug 1997 10:55:16 -0600 Does anyone know how to get Fractint working with a Matrox Millenium video chip?

Fractint supports VESA 256 color modes, so the problem boils down to getting your board to support VESA. Most boards either have VESA built into the BIOS or have a little TSR program that adds VESA support. Failing that, there is a shareware TSR called UNIVESA that works pretty well for nearly every video board under the sun. Remember that Fractint does not yet support truecolor - we're talking 256 color VESA modes. (Fractint does have some truecolor drivers built in, but they don't do anything yet.)

First, there's an interesting page that discusses this problem at http://www.animatedsoftware.com/faqs/vesa_err.htm On this page there's the following link: http://www.animatedsoftware.com/ftp/p11_ftps.htm I can't tell you if this a good or latest version - I found this info searching for Univesa. In the process of doing this, I remembered that the company is scitech. I looked up their page, and found this: http://www.scitechsoft.com/sdd.html They have apparently changed the name of the product. The link listed earlier must be older. Let us know if this works.

Since I've joined this group a few days ago, I got many interesting mails. As I can read, new users like to tell a little bit about themselves. So I shall do the same. (You can read this before going to bed, if you have sleeping-problems.:-) My "first contact" (not the movie) with FRACTINT was, I think 1990. In this time I read somthing about fractals in a scientific magazin and thought: "What the hell is that! It looks great!" So, therefore I bought some shareware to create my own nice fractals. But - I hope no one will treat me now - FRACTINT wasn't my first choice! But it was included in that shareware-package. I used a DOS-program (I've forgotten the name) with nice menus and mouse controlling (a little bit "windows-spoiled") and found FRACTINT complicated to use. This program was only able to create a mandelbrot-set and was also very, very, very SLOW. As I get bored about this program (a few weeks after I started it the first time) I tested the other programs I found in my package. And one of these was FRACTINT 16.11. After printing the manual (took a very loong time on my matrix printer) I read it :-). I have read of course, only these parts I needed to create a simple mandelbrot-set. I was amazed. It took only seconds to finish the image - the other program needed more than 10 minutes! - on my 286. So at this point I wanted to know more about fractals. So I bought a book. Which one? At that time I thought a book from the "discoverer" of fractals Ben=F4it Mandelbrot couldn't be the worst. It really wasn't, bu= t it's a very hard stuff to read. Now some things are different since my first fractal-creation: Everything changes (my operating-system - now using OS/2), get's faster (my computer, FRACTINT), older (myself) but also better (FRACTINT and myself again ;-). Okay that's it! If you are still awake I've a question (I think Jacco Burger has asked this Q already): How can I download the older mails of the list and more interresting: which file should I download?

TrueMand uses the Vepstas algorithm. Check out the TrueColor gallery on my web page (via IFL :-) ). The last z value is available in Fractint as LastSq (I may have the name wrong, but its something like that). My intent is that the pseudo continuous iteration value be calculated within the formula parser, then multiplied by, say 1000, and the integer part equated to Z.Real, using the real option in Fractint. That should provide iterates.tga with the pseudo-continuous interation value times 1000. After appropriate treatment of iterates.tga, a 256000 color fractal should result.

The subject line gets a little off track. >>>Jay Hill wrote "Peter Otterstaetter posted" and Sylvie Gallet answered with the formula. Fractint can be mislead into writing the wrong source for a formula into a parameter file. This really doesn't hurt because it is very thorough in searching your formula directory when the named source is wrong.But, there always is a but, it will only find one. Orgform is very thorough in compiling any formula file you give it, even filing away duplicate names and formulas in a seperate file. After a period of use the directory becomes a little disorganized. Fractint presents the list nicely organized but when it does a search it goes through the files in the order they appear in the directory. At the moment my setup has the _l_dup.frm appearing before the _l.frm file so it ends the search at the duplicated name, with sometimes disasterious results. Tim Wegner is open to suggestions that anyone might make about what search method they would like to see. To get even farther away from the subject I notice that when anyone with a Compuserve address posts a parameter file that every equal sign is followed by 3D. Apparently their mail program is set for a line length of 72 and any line it wraps ends with =, and any line that starts with an equal sign the next character is turned into its ASCII hex code. Anyone else notice this? It could cause some problems for a beginner. This wouldn't be the first time I have seen a strange happening that as far as I can tell nobody else sees.

I would like suggestions for a better behavior by fractint in searching for formulas. In fact there probably needs to be more than one behavior that the user can select. I'm very ambivalent about the ability of Fractint to search for formulas. As Charles pointed out, it means that if multiple formulas with a given name exist, you're not sure which is being used. Maybe Fractint should have a "thorough" option where it seaches ALL frm files even if it finds a formula, and presents the user with a choice of which one to use, or at least give a warning, instead of quietly quitting when a formula is found. This would slow performance of course.

Zooming out from Julia? shows the path I took in and the amount of structure that shows up. Reducing the bailout to clear up the background doesn't work. At 16 or lower the image disappears. It is tempting to guess that there is a baby Minibrot at the center of the four arm spiral. It persists up to a magnification of 2E30 where I quit. Is this one of the whirlpools of self similarity Tim speaks of? I don't remember what led me to Crystal_defect but other odd things happen here. Gradually raising the bailout at first makes the pattern more distinct and then more pixel colors appear. At 255 almost the whole screen is chaotic. At 256 the whole screen goes high count. Zooming in on the chaotic area doesn't seem to change anything up to at least 2E29. Here my patience gave out again. Zooming in on the single red pixel in the Crystal_defect shows form attached to the apparent random speckles, but few red pixels appear for several maximum zooms. By about 2.7E36 the pattern is parallel red lines that are broken by what seem to be incipient new patterns. I gave up again. All of which doesn't give any answers but it's fun to speculate.

This would give the user some confidence about which formula is being used if there are duplicate named formulas. If the user wants to use a formula in a duplicate file, he can either specify the duplicate file in the par entry or use the "g" option in interactive mode to select, for example, "formulafile=_b_dup.frm".

There are so many different ways to distribute PARs, including having them embedded in the gif89a file, that I can think of no reasonable way to make *certain that the correct formula is being referred to. But I wouldn't object to seeing all the PARs on this list accompanied with their corresponding formula. Does anyone else feel this way? I feel, however, that slowing Fractint down because some folks don't give their formulas unique names is probably a bad idea. I'd rather hand-check for duplicate names if the PAR doesn't work, or ask the person who posted it to post the formula if people have problems. Hmm.. A random idea. I have no idea if it's a good one or even possible. Perhaps Fractint could be bundled with a small utility that checks your FRM files for duplicate names, a'la Orgform, and write a file containing this info. Fractint could then check this SINGLE file before running a PAR, and pop up a warning if formulas with the same name exist. Would that slow things down so much? This utility would only need to be run when new formulas are added, and it could be done manually by the user. Or perhaps a CHECKSUM could be run on the default FRM directory when Fractint is started, and the results written to a file. If the CHECKSUM changes, Fractint pops a message up telling you you may need to run the aforementiond utility. (I'd ask for a command-line option to override this behavior, of course...) One more thought... I sure hope someone named Roberta Carr doesn't start formula writing, or we'll all be screwed!

I also promised to check into iterates.tga - and make sure it is working OK, but I haven't done this yet. ITERATES.TGA works just fine here. I have tested the Targa files produced with several different readers, and they are all legitimate files. A few non-standard readers might assume the header length is always eighteen bytes, rather than checking the header itself, but this is not a problem with FractInt. Adding extra parameters to ITERATES.TGA would be somewhat helpful, but most of the really cool coloring algorithms (in my opinion) require access to the entire set of orbits. This cannot reasonably be stored for every point--one image I computed recently had a *minimum* iteration count of over 200,000. At twenty bytes per iteration (two 10-byte long doubles) this is four megabytes, and that's just one point.

I don't find the time taken by my 486/33 to go through the non-duplicate formulas to be so great that I could not wait a few seconds more than that to make sure I'm generating the right image.

Date: 27 Aug 1997 14:27:45 -0600 (MDT) Rich, I have noticed this too. The full number of decimal places shows up when you press [TAB], but when you make a parameter file for a deeply zoomed image, the corner locations are truncated. This prevents folks from using parameter files to create very deep-zoom movies, among other things... I'm going to guess it's a limitation of the data type that Fractint is looking to read from a parameter file (double long float or something like that, eh?) Suprisingly, however, even though the corner locations are truncated, the parameter file seems to be able to recreate the exact image nonetheless! If there _was_ a way to produce a .par file with 100 digits of accuracy on the corners, I'd be psyched! I have my reasons...

I also use Fractint in Windows NT 4.0 with Matrox video card. But, I have Mistique with 2Mb. First time I also had the same problems.

Yes, it's a known limitation. Look at the screen and see how much space is taken up by all the digits of the numbers. The screen would require a total rewrite to handel arbitrary precision. For now you need to save to a PAR file and edit the file to get the effect of the screen.

I have tried to run Fractint under 2 different NT 4.0 boxes so far. Both are P Pro 200 with 128 Mb of RAM. One uses the Number 9 128 series II with 8 Mb of VRAM and the other uses the Matrox Millennium with 4 Mb of WRAM. Neither one will run Fractint in anything higher than 640x480. 8 bit color is only available at 320x200. So far I have not bothered to dual boot either of these machines with DOS. It's a great pity, too. I had really looked forward to being able to generate some of the more time-consuming fractals under the P Pro 200's. Any ideas as to why this would be the case?

I was just hoping that the code within fractint that writes iterates.tga would be modified (by Tim maybe ) so that it writes whatever is used for the color lookup instead. Then, for example, putting a pseudo-continuous iteration value into real portion of z and selecting real as the coloring method, iterates.tga would contain the pseudo-continuous iteration value. It could be scaled beforehand, by say, 1000, so that the data to the right of the decimal point would be included in the integer written to iterates.tga. A simple formula example follows which would work if fractint were modified in how it writes iterates.tga: ============================ TrueColor { ; formula to place a pseudo-continuous ; iteration value in the real portion ; of z. z = c = pixel i = 0 zb = 0 bailout = p1: IF (|z| <= bailout) z = z*z + c i = i + 1 ENDIF IF (|z| > bailout) zb = z z = z*z + c ; These extra iterations z = z*z + c ; are added as suggested ; by L.

Version 19.6 added the "frm:" feature for including formulas in par files, and changed somewhat the sequence of events in a formula search. (BTW, there is a bug in the 19.6 "frm:" feature which appears when a formula and image entry in a par file have the same name - this has been fixed for the next release). The Fractint documentation does not get into detail about how the program goes about finding a formula, lsystem or ifs entry. Here is that detail: I. Item selected from menu screen in interactive mode: a. The item selected is always the one highlighted on the screen. II. Item is named as a command parameter in a .par file a. First, some definitions: 1. Default directory - the directory where the default .frm, .l, or .ifs file is located upon starting up fractint. 2. Current item directory - the last directory from which a formula, lsys, or ifs item was selected, as applicable. 3. Current directory - the directory you were in when you started fractint, unless you changed it by shelling to DOS. 4. Default extension - .frm for formulas, .l for lsys, .ifs for ifs, and .par for parameter files. b. Phase one - look for the file named in the parameter entry. If the file is found, look for the named formula, ifs or lsystem entry. If the entry is found, the search is done. If not, continue the search. The file search goes like this: 1. Look for the named file in the current item directory (this must be first so that I. above works correctly). 2. Look for the named file in the current directory (only if curdir=yes is in effect) 3. Look in the .par file itself (the entry must have an appropriate prefix) 4. Look for the named file in the default directory. c. Phase two - do a general search of the default directory in files having the default extension, checking each file one by one until the sought for entry is found, at which time the search ends. If not found, bzzzt the user. If there are two formulas with the same name in two different .frm files in the default directory, there is no guarantee that the correct one will be selected by the final general search; nor is there any guarantee of the order in which the files will be processed during the general search. If two formulas in the same .frm file have the same name, the first one will *always* be selected, even if you select the second one from the menu screen in interactive mode. Under the current system, it is critical that formula writers give their formulas unique names; the more active formula writers have done this by including their initials or some variation of their names as part of the name of each formula they write (e.g. Carr3192). You can also consult the orgform compilation to check whether a formula name has already been used.

I'd agree with this approach. You'll have a lot more control over how the image is printed, as well as a completely current driver, by using a Windows program. FractInt just can't (and IMO shouldn't) try to provide support for every printer. Personally, I've had decent results (for the price) by rendering at 1600x1200 or higher and printing on my Epson Stylus Pro. Using the stiff glossy cardboard-like paper runs about $1 per sheet, but as I said, for the cost, it's great. Damien M.

The ability to leverage the full speed of PPro 200's and P-II 300's at very high resolutions (1600-1280 or even 2000x1600) would be so much more useful to me than 24-bit color.

I noticed that it was darned annoying testing out PARs and their related .frm files downloaded from this list and other sources, because Fractint would invariably search through all my _*.frm files before it started searching through the new .frm files I'd just added to my formula directory. (Running Orgform takes a while, and I only do it when my formula directory starts filling up.) But you *can predict which .frm files Fractint will search first. It searches the files in the order which they were added to your formula directory, not based upon the .frm filenames or timestamps. If you use the DIR command at the DOS prompt, you'll see that the order in which the files are listed is the same order that Fractint searches your files. Same thing using the "Sortorder - None" option with LIST.COM. Simply making a temp directory, moving all your .frm files into it, and then copying them back one by one in the order which you would like Fractint to search them seems to work just fine. Of course, a batch file greatly speeds up this process. :) (I'll post an example of this batch file if anyone cares enough to ask.) An example. I have a ton of formulas that I just got from Paul Derbyshire's excellent web-page. I haven't yet run Orgform on them, and they are stored in a file called DERBY.FRM. But when running his PAR files, Fractint searches through every OTHER .frm file before it reaches DERBY.FRM, because it was the most recently added file in that directory (subtly different from the file with the most recent timestamp). So my disk churns away for many unneccessary seconds, when *I know where the darned new formula is! Just running my handy batch file whenever I download a significant number of .par and .frm files forces Fractint to search through the files I want it to search before it tries the _*.frm files. And it takes a heckuva lot less time to move these files back and forth than it does to run Orgform more often. - Sean --- ****** Sean or Jaq Pratz * spratz@freenet.edmonton.ab.ca ****** * o \ o / _ o __| \ / |__ o _ \ o / o * * /|\ | /\ __\o \o | o/ o/__ /\ | /|\ * * / \ / \ | \ /) | (\ /o\ /) | (\ / | / \ / \ * *************************************************************** Thanks for using Fractint, The Fractals and Fractint Discussion List Post Message: fractint@xmission.com Get Commands: majordomo@xmission.com "help" Administrator: twegner@phoenix.net Unsubscribe: majordomo@xmission.com "unsubscribe fractint" ------------------------------------------------------------------------------- From: "Paul N.

This is a good test to see where problems really lie. But under Win-NT 4.0, you have to do a Shut Down, Restart the computer, and when the OS Loader menu appears select the Windows NT Version (Server or Workstation) 4.00 [VGA mode] option. Then test the problem. If the problem does not occur, you may have a problem with the installed video driver. Where you would then consult the video adapter manufacturer to obtain an updated video driver.

Because Linux is free and not everyone wants to pay a lot of money for an operating-system which he (or she) does only need for creating fractint-images!

I absolutely do not need the integer math tricks because im trying to port it for a power-mac, and it really doesnt need to be as fast as possible. Also, fractint seems to have some really great color palettes. I looked at some docs and stuff a *little* but not enough to understand how they are generated. Does anybody have any pointers?

Worth a look, but this would constitute a *major* change in the way Fractint handles the identification of formula, par, ifs, and lsystem entries. Also, there is a fair amount of formula rewriting going on. For example, quite a few formulas have been rewritten to take advantage of the new if..else feature of the formula parser. These formulas look much different than the originals, and run much faster; but in fact draw the identical images as the original formulas with the same underlying math. I wouldn't want to lose the ability to have such improved formulas automatically used by old parfiles, as they can be now because the formula name remains the same. And Sean Pratz wrote: >I noticed that it was darned annoying testing out PARs and their related >.frm files downloaded from this list and other sources, because Fractint >would invariably search through all my _*.frm files before it started >searching through the new .frm files I'd just added to my formula >directory. I'll look into adding a command line option to specify the directory in which Orgform files are located. Then the search order could be "default formula directory" followed by "Orgform directory". A nice side effect is that only one file in the Orgform directory needs to be searched; for example, if the formula name is "abc", the only file that needs to be looked at is _a.frm. If it's not found, there won't be a formula of that name in _a_dup.frm either. Another benefit would occur when there are two "abc" formulas, and the one you want to use is in _a_dup.frm. By copying _a_dup.frm from the Orgform directory to the default formula directory, you could be sure that the search will select the formula you want.

While Linux and Free BSD are free, most users will never be adept enough to dual boot their machines with these packages. Millions of people will be getting NT or 95 in the upcoming years, though. Regardless of whether Fractint is ever made 32bit or multithreaded, it does not seem to run seamlessly under 95 or NT in all instances. I have now tried it on 3 NT 4.0 boxes, each with a different video card from different manufacturers and higher res modes at 256 colors just won't work on any of them. I have also tried it on 2 different 95 boxes, and 1024x768x256 won't work there either unless you reboot into DOS mode. Some of my graphical DOS software have the same problems, others do not. For example, 'CHAOS - The Software' (now sadly out of print) runs perfectly on every box I have tried it on. Of course 32-bit and multithreaded would be just lovely! The sped issue alone would justify that. I certainly wouldn't turn it down!

This is an interesting idea, but when you try to implement it, there are problems. Trivial changes in algebra would change the "hash count", as would changes in names of variables. Still, it's worth reconsidering. But for now, serious fractal fanatics need OrgFrm or something similar.

Also under Unix. It has nearly every feature, though it's slower because the assembler was translated to C. However Linux is not the total answer because the installed base is very small compared to Win95/DOS. We've given a lot of thought to this platform question. We are seriously hamstrung by our current 16 bit programming environment. Perhaps a better solution would be to port to djgpp, the free extended DOS GNU compiler. Such a port would still be a DOS application, but would have 32 bit memory access. The future probably holds a more portable Fractint that runs on many platforms.

I personally have had ideas for three or four years that I haven't gotten around to implementing yet. Fractint's development goes in fits and starts, according to the interests and abilities of folks who decide to be Stone Soup developers. Fractint could die on the vine in it's present version (probably won't :-)). It is also possible that an energetic developer will burst on the scene and just do the Win95/NT port, so you'll have it in a month. There are also many in between scenarios. :-) I'd say a Win 95/NT port will happen, but not overnight. But I can't predict for sure. BTW I'm following the NT/Matrox thread with interest. Unfortunately I have neither NT nor a Matrox, so I'm helpless to comment. I really appreciate all the folks who have jumped in and shared (this is one reason for the list). Bert Tyler has NT. I don't think he joined the list, but I'll ask him to view the achive web page and search for "NT" or "Matrox".

Until then I would always exit from Windoze and reboot to MS-DOS. After tinkering for several hours with the settings in the Fractint Properties menu, I finally got Fractint to behave correctly (on my system at least), and I e-mailed Tim to tell him of my trials and errors. Go to your Fractint folder and click once on the Fractint icon. Go to the File menu and select "Properties." Under Program, type in on Cmd_line where you have Fractint installed, e.g., C:\Fractint\Fractint.exe Click on the Advanced button on the Properties page. Place a check mark next to MS-DOS mode. Under a new MS-DOS configuration on the same page, put in the settings you use for your config.sys and autoexec.bat files under MS-DOS. DO NOT type in the config.sys and autoexec.bat files you use for Windoze. If you do, then you'll have all sorts of problems, such as Windoze telling you it doesn't have enough memory to run Fractint. The other menus under Fractint Properties do not need to be addressed. If you still have problems, please don't flame me. I got Windoze to work with my system and you may have an entirely different configuration. Basically, I'm running a 486/66 with a VESA-supported video driver and 24 Megs of memory.

Yes, this has come up dozens of times, and I've probably gotten the answer many times before. I'll look through my mail archives and combine the suggestions I've received. I'm actually pretty good at setting up things like Win95. But on a home system, I do it once, so after a year or two I no longer remember what I did FWIW, here are the settings I use for my generic "MSDOS" button. I am not claiming these are optimum, only that they work for me. I don't use a "fractint" icon, I go to the DOS prompt and then run Fractint (under Win95, not rebooting to DOS.) MS-DOS icon properties: Under memory, all the settings are "auto". The "protected" and "Use HMA" boxes are not ticked (should they be?) Under "screen", all the boxes are ticked, and usage is "full screen". Under "misc" I have disabld the screen saver, which can really mess you up. In my config.sys (among other things) I have: DEVICE=C:\WINDOWS\HIMEM.SYS DEVICE=C:\WINDOWS\EMM386.EXE NOEMS files=100 buffers=20 DOS=HIGH,UMB FCBS=4,0 STACKS=9,512 It is important to has as much free memory as possible. Mem shows "largest executable program size" of 543K which is OK, but not great. With this much, if I run fractint debug=10000 the fractint reports 86128 far bytes free. This works reasonable well. You wouldn't want the largest executable program size to drop much below 500K. Any other words of wisdom on this subject?

Jones" Subject: (fractint) FractInt in Windows 95 Date: 30 Aug 1997 13:49:30 -0400 Hello, A couple of years ago I was trying to use FractInt under OS/2. I had problems with certain display modes; some would work, some would not. I altered my FRACTINT.CFG file to force it to use VESA modes, and this worked. I no longer use OS/2; I use Windows 95. However, I've noticed that FractInt still runs well with the VESA modes. My FRACTINT.CFG line looks like this: -----8<----- Start FRACTINT.CFG F2 ,VESA Standard Interface ,4f02, 101, 0, 0, 28, 640, 480,256, F3 ,VESA Standard Interface ,4f02, 103, 0, 0, 28, 800, 600,256, F4 ,VESA Standard Interface ,4f02, 105, 0, 0, 28,1024, 768,256, F5 ,VESA Standard Interface ,4f02, 107, 0, 0, 28,1280,1024,256, F6 ,VESA Standard Interface ,4f02, 120, 0, 0, 28,1600,1200,256, F7 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11,1024, 768,256, F8 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11,2048,1536,256, -----8<----- End FRACTINT.CFG I removed the comments at the end of each line so it wouldn't get garbled through posting. Fixing your video modes this way helps quite a bit, but there are some other things that you may want to do. First, in the [fractint] section of your SSTOOLS.INI file, look for "textsafe=". If it doesn't say "textsafe=save", change it (or add the line if it is missing). This will protect your FractInt screen when you switch away from the program to another application you're running, but you should still ALWAYS switch to a text screen (by pressing TAB or ESC) if your fractal is still generating. Otherwise when you switch back, your image will be preserved, but FractInt will resume drawing in the wrong place on the screen, corrupting the image. If the image is done generating, you can switch away from the graphics screen directly. Second, tweak your settings for FRACTINT.EXE. Locate FRACTINT.EXE, right-click, and select "Properties". (If you launch FractInt from a shortcut, especially one on your Start menu, you need to locate the shortcut itself, right-click it, and choose Properties. You can work with shortcuts on your Start menu by right-clicking it and choosing "Explore".) Under the Program tab, make sure "Close on exit" is checked. (This is a convenience only, and will make Windows close the DOS box when FractInt exits.) In the Memory tab, leave all the settings on "Auto". Under the Screen tab, choose "Full-Screen". For the Misc. tab, UNcheck "Allow screen saver" and "Always suspend". (Note about Always suspend: this makes it up to you to suspend FractInt by switching to a text screen before switching away from FractInt. Since you have to do this anyway, leaving this option unchecked lets you use Disk/RAM modes to render in the background.) Click OK to save your settings for FRACTINT.EXE. IF everything went well, FractInt should run reliably from a DOS box inside Windows, and still let you switch away from it if necessary and run other Windows programs (with the warnings above). I do this a lot, even though other programs tend to run slowly with a DOS box open. Hopefully these comments will help someone. Damien M.

The results were beyond belief. I repeat the letter here in case some of you are not mambers of fractal-art. I probably do not belong in this group although I do use Fractint and am very partial to fractals. I came to fractals late in life, being introduced by a friend who is a retired professor at the U.S. Naval Postgraduate School in Monterey. In the beginning I just played with fractals in a program called "Fractool". Then after being laid low by a stroke and being unable to work I came back to fractals. I found a number of generators (including fractint) that I could play with and as long as I was now a 70 year old cripple I really wanted to do something with fractals. I fell back on an old hobby, that of making hooked rugs. Finding that fractals made a great rug suitable as a wall hanging or as a throw rug. I now make my hooked rugs from 100% 6 ply wool utilizing fractal images as my pattern. I recently made a fractal rug for a N.Y. fractal artist which he will include in a show he is having this fall. This was to be a copy of one of his fractals. When he received the rug here is a quote of his reaction: "It is really quite remarkable. I think the right word is luxurious. It is clear the amount of work that went into it is extraordinary. It's rich texture, weight and thickness are all a great and pleasant surprise to me. My wife thinks it's gorgeous." If any of you would like to see a picture of my work, Email me and I will send one back to you.

Subject: (fractint) DOS vs. DOS Window Date: 31 Aug 1997 09:57:10 -0500 I use the following solution for a good an controlled performance of the Fractint under Windows 95. I have a system with the following characteristics: Pentium MMX 166MHz processor. 32 MB RAM S3 Virge video driver card Fractint 19.6 program 1) Create a shorcut (Go to Explorer, select Fractint program, click right button, select Create shorcut) 2) Still in the Explorer select the "Shortcut to Fractint", open Propieties (Right click) and select the option for full screen running (Select Screen tab, then select Full Screen) 3) Change the Explorer into a Window (If not already there) and drag the "Shortcut to Fractint" file to the Desktop. ¡EUREKA! Now you have an DOS Icon in the Desktop that send you directly to Fractint without any problem. With + you can go to other applications, leaving Fractint working in its own background window. You can change the name and Icon of the shorcut in any moment, right clicking the icon and selecting Propieties. I use the icon that came with the Windows version of Fractint ¿How? Easy. Select change icon, and browse to the file of Windows Fractint (You have to already have installed this file), and then select the icon. I expect that this procedure will work in any system, except if the video driver is very special, and the system registers will be changed from within the Fractint, then when return from Fractint you will have a nice stuck computer.

It calculates pretty fast. To keep my impression a secret until you have formed your own the name is encoded by typing each letter one character higher. By increasing the itteration count a much more branched structure develops but then the background color becomes one of the bands in the figure. Finding a good color scheme is one of the hardest things for me to do. Thats about all of the lecture. To keep the file small all the co;ors that don't show are set to white.

This machine is totally different from the system I normally use. Using the information I posted about running FractInt in Win95, I set up FractInt on this new machine. It ran flawlessly the first time. Now, if I had a few more systems to test it on, I would, but that should give some reassurance that it's not just a fluke. :) Damien M.

Among other things I intend to make it object-oriented (C++ with optimised C/asm for inner iteration loops) and thus easily extensible (I notice Fractint, though written in plain C, uses structs with embedded function pointers to achieve an object-oriented construction) and all the features of Fractint. On the "wish list" of things I will try to implement are compatibility with Fractint par and frm files (and more powerful native par and frm alike files) and all formula types in Fractint. This would make ProtoMatter backward-compatible with Fractint, and thus a possible (but renamed) "Fractint 21.0". Of course if anyone, especially Fractint contributors and authors, wishes to collaborate over the 'net I would find that helpful and pleasant. Also on the list of intended features: the "disks" algorithm for rapid monochrome distance-estimator images, the synchronous orbits algorithm (depends on feasibility and ease of implementation/debugging, an early attempt of mine to code a synchronous orbits algorithm on an Amiga resulted in guru meditation and other bugs which proved overwhelming at the time), plug-ins (DJGPP DLM's plus datafiles, coding the iteration functions and containing parameter data), and user-definable parsed formulas for such things as color mapping, x/y mapping (an atan mapping of radius might be interesting on some infinite fractals like the Julia sets of rational functions), and so forth. Formulas will be compiled internally to either a byte-code that will run more rapidly than an interpreter that has to parse ascii, or perhaps if it is feasible to native machine code. The former will be platform-portable, the latter would have to be implemented for every platform to support. (All platform-dependent code will be in separate modules with a platform name attached, e.g. dosvideo.c for handling the video in DOS; some sort of makefile will be used that can be switched for compiling for different platforms.) -- .*.

However, what do the numbers mean? They seem to be undocumented but of some sort of importance since 'b'-generated pars are always full of them. My personal guess is, perhaps these are interpreted into an 11-bit bitfield that says which items aren't explicitly set and must be reset in the par? Still, why bother instead of just resetting them all, since resetting say the logmap only to then set it to 187 isn't THAT many wasted cpu cycles... -- .*.
