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" ------------------------------ Date: Tue, 12 Aug 1997 10:12:41 -0400 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" ------------------------------ Date: Tue, 12 Aug 1997 16:34:23 -0700 From: "Jay Hill" Subject: Re: (fractint) Welcome folks! Hi all, I'm Jay R. 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. May you have a fractal life.

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. - ------------------------------------------------------------ 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" ------------------------------ Date: Tue, 12 Aug 1997 19:29:42 -0700 From: "Mike or Linda Allison" Subject: Re: (fractint) Welcome folks Yes, Sylvie!
