For any point c inside M you can find its component center through Newton iteration if you calculate the derivative of z and the period of c which is the period of the component. Then calculate Taylor coefficients for the mapping p:W->D. These coefficients, the center and the period make up a set of "parameters" which describe the component. Now if you suspect a point c to be inside M, calculate the approximate value of p(c) for a list of components you set up as you scan the image. If p(c)<1.0 then c is inside the component. In-depth coverage can be found in Jay R. Hill's article in "The Future Use of Fractals".

But what is the mapping p? For a disk, it's (x,y)*const+(a,b) for the center a,b and radius const of the component. How do you determine, though, that it is a) a disk and not a cardioid, b) const and a and b, and c) what are the mappings for cardioids etc.? -- .*.

It occures when the bailoutest-parameter (z-screen) is combined with continuous potential (y-screen). I had an image in which the bailoutest parameter was set to imag and continuous potential activated. I wanted to examine the effect of different values for the potential-bailout value. So I stored the image to a parameter file with the b-command, changed the pot.-bailout value a few times and stored every image to the parameter-file, without letting Fractint fully calculate. I made a DOS batchfile and let it run. To my surprise I found that in the first image the bailoutest-value (z-screen) was set to imag, in the other images the bailoutest-value was set to the default-value of mod. When I examined the parfile I noticed that only the first entry had the bailoutest=imag statement. In the other entries it just wasn't there. I tried this procedure another time and the same thing happened again. So it looks like as if when you change the potential-bailoutvalue and use the b-command to store the image to a parameter-file, Fractint ignores the bailoutest=xxx command and doesn't store it. I have a parameter-file attached. Can someone please have a look? I know I can fix the file by editing it with a wordprocessor, but that is quite a hassle every time. Is it possible to have this fixed in the next version of Fractint? Thanks in advance! Cheerio, Jacco e-mail: Jacco.Burger@BU.TUDelft.nl (By the way, please let me know if the par-file isn't attached.

Thank you very much. I should have known it must be easy. :-) Now, is this a bug? Might pass as FoTD if it had a romantic story to go with it. I zoomed in on the right most period 12 midget and switched to the Julia set view. Now look at this. Something is wrong. A flaw here at magnification 1063 begins at magnification 20. Press the space bar to see the midget, up close. It is one from my complete collection (coordinates found as part of the MSet area project). Speaking of collections, did you know Fractint has a limit of 2000 samples in a par file? I found out! The latest Pentiums are fast enough that it takes longer to press SHIFT-@, DOWN arrow, ENTER than to draw the image. Is there a 'next' par image key which will get the next one without leaving the graphics mode? Also, in zooming in, it takes longer to get the dozen or so PageUp key strokes in than to draw images. At least until you are at 1e12 magnification or so. A keystroke to get the max-zoom box would be nice. BTW, the fact that the zoom box stays centered on the center coordinates is very useful. Looking for very small features is easy when you have the coordinates. Of course, you can press Z, F6 and type in a new magnification. But the view along the way is the fun part of zooming. For deep zooming, I use a trick to make Fractint draw a small view for early sampling and still keep the 1024x768 setting. It is to put the zoom focus in the upper right of the little zoom box. Press ENTER to start the zoomed in image. Before it gets far (as quick as you can) press PageUP then CTRL-Right arrow forcing the calculation to the left side. Now the calculation will occur in the upper left corner. Usually I see the next level of interest in about 20% of the scan down the screen. If I have missed, I can hit PageUP, UpArrow and/or Left Arrow and fill in a narrow strip in those directions. This will help you in DEEPZOOM mode where you are looking for a midget (and hoping you are not caught in a Misiurewiz trap). Jay PS. If someone recognizes these colors, I admit it, they are from someone's post, but I lost track of whose. Let me know whose they are.

I don't think so, because the inside-disks approach is very different from the outside one (as you know, not just set x=1 instead of 0 and it works for inside disks as well).

At the component center this is 0. Besides Jay's article there's some about it in "The Beauty of Fractals" in the Mandelbrot chapter.

But for now, serious fractal >fanatics need OrgFrm or something similar. Let me be a bit more precise. The hash count idea requires a new thinking about a formula. Let a formula have a "description part" and one ore more "implementation parts". The "description part" describes the "formula mathematics" in a normalized formal format (which we have to define; OK lot of work!). The hash count (or fingerprint or whatever) is taken from the "description part". The "implementation parts" describe some implementation of the "formula mathematics" (like an entry in the well known frm-file). Changes in the implementation parts (like different variable names, if-then-else structure etc.) would not affect the hash count. So what we need to identify a formula is its hash count (or whatever) and its implementation name (if there are more than one implementations). Hope this helps to clearify the idea.

You are much better off using a third party program. If you are running Windows, get the shareware program PaintShop Pro. It is easy to use and does a great job of printing fractals on my Deskjet 870.

The hash count idea requires a new thinking about a formula. Let a formula have a "description part" and one or more "implementation parts". The "description part" describes the "formula mathematics" in a normalized formal format (which we have to define; OK lot of work!). < I'm always ready for new thinking! Perhaps you could give an example - here are two formulas, the second of which is a simple optimization of the first. These formulas would produce identical images. Could you show what the "description part" of each of these formulas would be? Presumably it would be such that if the formulas were written by different persons, the description part would be the same. Example1 { z = c = pixel: z = z * z + sin(c) |z| < 4 } Example2 { z = pixel c = sin(pixel): z = z * z + c |z| < 4 } A bit more challenging would be to take the "before and after" versions of the Carr2821 formula (you can get these in the if..else tutorial that is part of the fractint 19.6 package) and show how independent writers of these two formulas would generate the same descriptive section. Someone asked me a year or so ago if it would be possible to go through the Orgform compilation and weed out "duplicate math" formulas, so I have already given a bit of thought to the idea of formula "content". Some things are easy, such as recognizing that the name of a variable does not affect the underlying math (in fact, when orgform.exe decides to skip a formula because it is identical to a formula of the same name already in the compilation, it makes the comparison without regard to names given to variables). Order of operation matters are probably in range, such as recognizing that z = a*b is the same as z = b*a. Algebraic equivalency becomes harder; recognizing the equivalence of such expressions as (x+y)^2 and x^2+2*x*y+y^2 opens up a Pandora's box of Goedelian proportions. Developing an algorithm to recognize the equivalency of major rewrites such as with Carr2821 seems unimaginable to me.

The "G" keyboard command lets you give a startup parameter interactively. From there you can say periodicity=no to turn this feature off.

I am new to the list also, however I have been printing fractals for various purposes on my HP 660Cse for quite sometime. This is pretty much what I do, if it is any help: If I have constructed a fractal through fractint, I will save it as a .gif (smaller file than a .bmp) to the desktop (associated with LViewPro), and if desired make changes to the image if desired either in that program or another, then click on "edit" at top, "copy", bring up WordPad (or WordPerfect), click on Edit at top again, then paste. From there I will resize if putting on a postcard or using as kind of a logo thing on a piece of paper for letter writing, or to make a greeting card with - whatever, then click on "file" and "print". After which I then save the file (image) on 3.5 disk and remove the image file from the h/d. This is all under Win95. Hope this helps, and hope I did not waste anyone's time.

(ProtoMatter will include a command console for similar purposes.) Type "periodicity=no" and enter. To put it back later do the same but use "yes" in place of "no". The other: copy this and paste it in notepad and save as a par file, like "periodic.par": ----8<---- PeriodicityOff { periodicity=no } PeriodicityOn { periodicity=yes } ----8<---- Then use @ to load one or the other, to switch it on or off. (Since this has no reset= in it, it won't do a whole new image the way normal par files do.) Tim: any chance Fractint 20.0 could make periodicity switchable on the 'x' screen like floating point? Also, how about allowing formula writers to specify a default for floating point and periodicity? That way formula writers can force fpu math, and can default periodicity off for formulas (like many rationals or formulas depending on earlier iterations of z) that tend to goof up with periodicity on. -- .*.

In fact, Example1 and Example2 are two "implementations" of the same formula. So the "description" and "implementation" parts may look like: FORMULA { DESCRIPTION { z =3D c =3D pixel: z =3D z^2 + sin(c) |z| < 2 } IMPLEMENTATION { Example1 { z =3D c =3D pixel: z =3D z * z + sin(c) |z| < 4 } Example2 { z =3D pixel, c =3D sin(pixel): z =3D z * z + c |z| < 4 } } } Of course, it will be a hard task to create a "standard" for the description part!

There is no need to recognize rewrites or optimizations because this are "implementations"; just add it to the formula's implementation part (or exchange one implementation). To identify a formula, get the description part's hash count; if there is only one implementation, OK use it, otherwise, we have to decide which one FRACTINT should use. Or, FRACTINT uses always the first implementation and we exchange the implementations as we need them.

Why, exactly? Could you please explain xactly what you do - what video mode you are using, and how you know the image is bigger than the screen. Are you talking about Winfract or Fractint? Winfract uses a virtual screen that doesn't have to match the actual screen. Also, Winfract is no longer supported and is frozen in time forever ...

I don't think there is anyone in this audience that would disagree with you! The non-fractal postings violate the spirit of the newsgroup and the abpf newsgroup FAQ. Unfortunately, we haven't been able to find a way to stop them. Most of the people (and I use the word loosely) who post spam to abpf are making postings to alt.binaries.pictures.*. And abpf is caught in the net. Those same people usually have a financial interest in attracting as many others as possible to their web sites or their pyramid games. So they really don't care at all about the rules. To them, only their own self-interests matter. We tried to discourage them by requiring certain keywords (fractal, mandelbrot, julia, etc.) in the subject line, and then installing a retro cancel 'bot to cancel every posting that didn't include a keyword. We were hoping that when they got their postings cancelled from ALL the newsgroups by our 'bot, they would exclude us from their spam postings in order to protect their own interests. We were moderately successful (a RETRO 'bot can't be completely successful, plus some of the more inventive spammers started using the keywords in their postings!). Then, Dick Depew, the person who wrote and maintained the retro 'bot, had some rather serious computer problems, and for the last 6 weeks or so, his computer has been down more often than not, so we are getting spammed again! Hopefully an end to Dick's problems is in sight, but no promises can be made! We keep trying . . . If anyone has a brainstorm on how to solve this problem, please speak up! Consider this a cry for help!

Tim) Hi, I have had the same problems with NT 4.0 - and still have them. I asked several questions to Matrox' tech support but the answers couldn't help me. Here are CCs: ---Question #1--- Hi, I have problems with SVGA modes when starting DOS application from a DOS prompt, eg FRACTINT. My monitor can't sync any SuperVGA video mode! I have no sync problems with the Windown NT 4.0 drivers. In addition to that: it makes a difference whether I start FRACTINT from the DOS prompt in window on the Windows desktop or from a DOS prompt in full screen mode (text mode). In the first case FRACTINT says that these video modes are not available with my adapter, in the latter case it tries to switch into the SVGA mode (from 640x480x256 to 1280x1024x256) but obviously cannot sync it. Here's my configuration: Matrox Millennium, 4.0MB, RAMDAC TVP3026A, 220MHz, Serialnumber AAC42011, VGA BIOS-Version 2.3, MGA PowerDesk-Version 3.12.046, DisplayDriver Version 3.12.046. Monitor's horizontal line frequency: up to 84kHz. Do you need more info? Thanks, Stefan. ------ ---Answer #1--- Try the mgamon utilty from the setup directory on th mill cd. this will setup the monitor for dos mode. Chris. ------ ---Question #2--- Chris, I tried the mgamon.exe utility that came with the bios23 update but everytime I start it from Windows NT 4.0 it produces a horrible sound through my computer's speaker and then just says "No board(1)". What now? Thanks, Stefan. ------ ---Answer #2--- The mgamon.exe file was not intended to be used with windows nt. It is for dos, but can also work with win95 and win3.1 ThankYou ------ So I still have no idea how to solve this problem.

Be courteous to others by posting responsibly; you will not only help to improve the quality of Usenet but also avoid the backlash risked by ignoring basic rules of "netiquette". In a nutshell, newsgroups are a means of "public discussion". Newsgroup articles (messages) look like e-mail, but they can be read (potentially) by millions of people all over the world. Newsgroup articles are distributed via "news servers", which contain databases of articles, and are operated by Internet service providers, schools, universities, and companies. There is no "central" server on Usenet. A newsgroup article propagates from one server to another, starting from the server where it is first posted. "Moderated" newsgroups are sort of an exception, in that all articles are first forwarded via e-mail to a "moderator" for approval. The moderator posts them on his/her news server, and from there they propagate as described below. But different moderators use different news servers. Ideally, all the articles in a newsgroup travel to all sites (news servers) that carry the newsgroup. This means that when you post an article, the final result is tens of thousands of copies, all over the world. More specifically, when you post an article, it goes first to your "local" news server (operated by your Internet service provider, company, or school). Your server then sends copies of the article to its "neighbors," that is, to servers with which it has agreed to exchange articles. Those servers in turn send copies to *their* neighbors. Eventually every server that carries the newsgroup has a copy. Most servers normally send articles to other servers more or less in the order of arrival. This sequence can get scrambled for various reasons, which is why you often see responses before the "original" article arrives. News server administrators make arrangements among themselves about which newsgroups they exchange. The "receiving" server's admin tells the "sending" server's admin which newsgroups he/she wants to receive. The "sending" server's admin configures his/her server to send only those newsgroups. There are two methods that servers know which sites they've already visited and how a message avoids the same site twice. Servers usually use both of them, in sequence: 1. The "Path:" header line shows the sites that the article has traveled through, so far, between the originating server and the current server. If the "receiving" server appears in the "Path:" line, the "sending" server does not try to send the article because it knows that the "receiving" server has already received a copy. 2. The "Message-ID:" header line contains an identifying code which is different for every article. Before transmitting the article, the "sending" server asks the "receiving" server, in effect, "Do you have an article with Message-ID such-and-such?" The "receiving" server responds either "No, please send me a copy," or "Yes, I have it already," whereupon the "sending" server either sends the article or goes on to the next one. Each news server "expires" (removes) old articles, usually once a day, to make space for new ones. Most servers do this based on the number of days an article has been on that server. The "expiration time" varies from one server to another, and can also vary from one newsgroup to another, on the same server. It might be a few days, or it might be two weeks or more. So, even after an article expires from your own server, it is probably still visible on many other servers. Note, however, that even though you cannot see an article any more, it may still be present on your server. Most news-reading software keeps track of which articles you've read, and shows them to you only once. This way, you don't have to wade through the same articles over and over and over again. There should be a command or button or something which "shows all" or "shows previously-read" or "unmarks" articles, so that you can see all the articles that have not yet expired from your server.

Review...

The copy of my program below *should* compile for you with a C++ compiler (I use gcc with the -lgpp switch). The header reads in perfectly, and then the program is supposed to read in the first 100 pixel itteration values and store them in a dynamically declared array (if you have a tip on how to dynamically declare a 2d array, I'd be interested to hear it!). The first 50 iteration values read in just fine, but the next fifty are being misread. You;ve been a great help already, Damien; if you have any suggestions for me, I'd be grateful for the help.

I would like to be able to get an ASCII file (x,y,z) of the data that makes up a Plasma fractal. I looked for the subroutine PLASMA() in CALCFRAC.C but couldn't find it. (I'm a returning student and don't know 'C' yet either -- It wasn't around when I was last in college.) Is this possible? It seems like it would be almost trivial. Alternatively, does any one know the where to get the original PLASMA.ARC Pascal program distributed by Bret Mulvey or how to get in touch with him? Does anyone know of other Random Mid-point Displacement fractal generating programs that might have ASCII output?

Date: 07 Sep 1997 11:53:41 -0400 (EDT) I have a tiny question. I would like to know if there's a way to access the basic formulae in Fractint, ie, to see, say, the basic Mandelbrot formula in a text editor. I'm trying to understand writing formulae by attempting to reproduce the basic ones myself by starting with Lambdafn, and for the life of me I can't make anything Fractint will accept. This is what I came up with: Lambdafn { z(0)=pixel, (also tried z=pixel and z=0=pixel (monkey at keyboard approach)) z(n+1)=lambda*fn1(z(n)), |z|<64 } Naturally if I am unable to figure out something like this, my confidence in coming up with a new formula on my own is not very strong. No matter how I alter that, Fractint tells me (sternly, with that awful raspberry it makes when it dislikes something) that z is undefined. I've seen the formula for Mandelbrot in frmtutor.txt, so I have one, but I'd like to be able to see the others.--Alice, feeling doomed and mortified 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: rttyman@wwa.com Subject: Re: (fractint) Original Formulae?

Here's two things that will help you in creating formuals: At the DOS prompt where you have Fractint, type in "makedoc fractint" to create a lengthy document that explains all of the bells and whistles of using the program, including the various formulas that accompany it. You can either print it or read it on screen if you wish. You can also access the document directly within Fractint by hitting the F1 key. You do not have to type "makedoc fractint" to access the online document because it's part of the program. I mentioned the "makedoc fractint" command because many of us like to keep a print out by our side for reference while using the program. Also, go to http://spanky.triumf.ca/pub/fractals/formulas/ and download FRMTUT.ZIP. It's a PKZIPPED 41 kb file that'll teach you all about writing formulas. These two documents will answer all your questions. Furthermore, you can read the fractint.frm and other files with the .frm extension with a word processing program (or at the DOS prompt using the EDIT or E function) to see how other people write their formulas. And, you can study the formulas presented here or at the fractal art list server. Formula writing for Fractint is not hard and is lot of fun. Go to it!

Date: 07 Sep 1997 14:54:53 -0400 (EDT) I'm getting feedback that my question is not clear. Here is what I want. When you go into Fractint and hit T you are taken to the fractal types. I want the formulas for those types. Going to fractal type "formula" gets you to the formulas in FRACTINT.FRM. I want to know if there is a way to see the formulas as they would look in the text editor for the other basic types such as mandelbrot. I realize that when I see the mandelbrot and hit "z" I will get a blue screen that shows the initial condition and iteration. That information is insufficient for typing out a formula in a text editor that will make a mandelbrot. I showed that with my attempt to recreate the lambda formula, where I used the information given me by the "z" key to try to recreate the lambda formula. If there is a file in Fractint that lists the formulas for the types, I can't find it. --Alice On Sun, 7 Sep 1997, A M Kelley wrote: > Thanks Bob...I have Fractint.doc and Frmtutor, and they don't show the > basic formulae like lambda.

Alice, whenever you choose a formula to process in Fractint, and go to the parameter options screen, the formula is presented in a window underneath the options. Ie. you hit "T", choose a formula, then the next screen is the options screen. This is where you should be able to see the formula. Then you hit enter and the generating screen comes up and starts writing the fractal. Is this the information you are trying for here? The other option is to open fractint.frm in any text editor and printing it out. You will have a printout of every formula in that file (all the default formulas that show up when you hit "T".) Hope this helps. Oh, yes, hey everybody. I've been on the list for a few weeks. Mostly following the discussions and printing out the good stuff. I am an artist that studied physics for a short bit before I switched to art 25 years ago. Haven't given up my love of numbers yet. I will post a few of my works in the newsgroup or my web page sometime soon and let you all know. The discussion in this list have been helping me along some, but am using fractint on a 486 (running it on a zip drive disk) so some of the platform discussions don't do me any. Cheers, Oliver!

That is why I made the suggestion to read other people's formulas as well as the texts. If you do as I and others suggest, you will realize that you don't write z(0)=pixel, as found in many textbooks. Under Fractint, you would initiate with z=pixel: instead of z(0)=pixel. Instead of z(n+1)=z^2+c, for instance as your basic Mandelbrot formula, under Fractint you write z=z^2+c, omitting (n+1). Also by reading the Fractint document you will come to realize that *lambda* is not in the programmed vocabulary. Don't take what you read under section 2.12 Lambdafn to mean that you can write *lambda* into your formulas. Instead, read section 2.35 Formula, which shows you under *Predefined Variables* and *Precedence* what is allowed to be written into a Fractint formula. You will readily see that *lambda* is not listed, and, being unlisted, you cannot write it into your formula. This is another reason you cannot get your formula to work. Also fn1(z(n)) is incorrectly written as *n* is undefined in your formula initiator. fn1(z), fn1(z*c), fn1(z^2-1), and fn1(sin(z)) are some of the ways to write this part of the equation. So, instead of z(n+1)=lambda*fn1(z(n)), you could write something like z=sin(c)*fn1(z), and then, on the last line write |z| <= 64. One way to write the basic Mandelbrot set under Fractint would be: Mandelbrot { z=c=pixel: z=z^2+c |z| <= 4 } You would NOT write it as: Mandelbrot { z(0)=c=pixel: z(n+1)=z^2+c |z| <= 4 } It just won't work for reasons explained.

I presume that you want to translate the following informations into a formula: Real Part of Parameter 0.85 Imaginary Part of Parameter 0.6 Bailout Test (mod, real, imag, or, and, manh, manr) mod Bailout value (0 means use default) 0 (lambda default is 4) Classic Lambda fractal. 'Julia' variant of Mandellambda. z(0) =3D pixel; z(n+1) =3D lambda*z(n)*(1 - z(n)). Two parameters: real and imaginary parts of lambda. This algorithm can be translated as follow: lambda-1 { ; Sylvie_Gallet@CompuServe.com, Sep 1997 ; George, if you're lurking here: don't include it ; in the Orgfrm compilation :-) z =3D pixel , lambda =3D p1 : z =3D lambda * z * (1 - z) |z| <=3D 4 } But with real(p1) =3D imag(p1) =3D 0, you'll get a blank screen. In th= at case, a small if..else statement will set lambda to (0.85 , 0.6): lambda-2 { ; Sylvie_Gallet@CompuServe.com, Sep 1997 z =3D pixel IF (p1 || imag(p1)) ; if p1 different from (0 , 0) lambda =3D p1 ELSE ; if p1 =3D (0 , 0) lambda =3D (0.85 , 0.6) ENDIF : z =3D lambda * z * (1 - z) |z| <=3D 4 } Save lambda-1 and lambda-2 in a text file with the extension .frm (for example built-in.frm). In Fractint, hit and choose . The Formula Selection screen displays all the formulas included in Fractint.frm. Hit , choose built-in.frm and select one of the formulas.
