Not sure if zip files make it through the mail-list server, or maybe there is some other problem. (I am using Netscape that might not do uuencoding. :-( )) Maybe what would work better, if others have the same problem, is to post a query to see if anyone would like the file, and if so, send you a reply direct. That way, only the one's that want it get the big file. And you can send it to me, just zipped works fine. If I get anything out of it, will maybe send you an image, if that works for you. Glad you are getting organized in the midst of chaos. For most folks, putting your email address like this: mailto:oliver@nxs.net should make it a clickable text that one can then click on and do a message. Of course, just the address works if one wants to copy/paste. Thanks, Oliver! - ------------------------------------------------------------ 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: Sun, 7 Sep 1997 23:01:00 -0700 (MST) From: Kerry Mitchell Subject: Re: (fractint) New formulas This message is in MIME format.

Yes, you can have the word "lambda" in a formula but you must initializ= e it in the init section of the formula i.e. put it on the left of a "=3D" sign. "lambda =3D (0.85 , 0.6)" in the init section of lambda-2 means that th= e first value of lambda is (0.85 , 0.6). If you don't initialize lambda, its value is 0 and z =3D lambda * z * (1 - z) will be interpreted as z =3D 0 * z * (1 - z) and you'll get a blank scr= een. - Sylvie - ---------------------------------------------------------------------- Sylvie_Gallet@CompuServe.com http://spanky.triumf.ca/www/fractint/sylvie/gallet.html http://ourworld.compuserve.com/homepages/Sylvie_Gallet/homepage.htm - ---------------------------------------------------------------------- - ------------------------------------------------------------ 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: 08 Sep 97 07:35:22 GMT From: wdelange@biochem.nl (Wim de Lange) Subject: Re: (fractint) [fractint] oops!

Hello Alice and gang: I'm being very patient in explaining how to write Fractint formulas. In my last message posted Sunday, I said that all terms that can be used to write formulas were listed in Fractint document, Section 2.35 Formula, under *Predefined Variables* and *Precedence.* I further stated that *lambda* was not one of those terms. Sylvie Gallet then posted this formula afterward: > > lambda-1 { ; Sylvie_Gallet@CompuServe.com, Sep 1997 > ; George, if you're lurking here: don't include it > ; in the Orgfrm compilation :-) > z = pixel , lambda = p1 : > z = lambda * z * (1 - z) > |z| <= 4 > } > Alice sees this formula and then states that I, Bob, said one could not use *lambda* in a formula. I again reiterate that *lamba* BY ITSELF (I'm further clarifying here with the emphasis) cannot be used in Fractint formulas: Mademoiselle Gallet's formula is not written as: lambda-1 { ; Sylvie_Gallet@CompuServe.com, Sep 1997 z = pixel: z = lambda * z * (1 - z) |z| <= 4 } If it were written that way, it wouldn't work. What she wrote in her initiator was z = pixel, lambda=p1: She is RENAMING P1, a term listed under *Predefined Variables*, as lambda. She could have just as well typed z=pixel, chickensoup=p1: or z=pixel, alicekelley=p1: The formula would work using chickensoup or alicekelley, which are not found in any of the terms listed under Section 2.35, because *p1* is being renamed. But if she didn't tell the Fractint compiler that she was renaming p1 *chickensoup* or *alicekelley* then the formula wouldn't work (see next example). Next Example ============ This will work as a Fractint formula: Chicken_Soup-1 { ; Bill Clinton@Governmentserv.gov z = pixel , chickensoup = p1 : z = chickensoup * z * (1 - z) |z| <= 4 } This one won't: Chicken_Soup-1 { ; Bill Clinton@Governmentserv.gov z = pixel: z = chickensoup * z * (1 - z) |z| <= 4 } I hope I've made myself clear this time. Now go forth to write many interesting formulas and have a nice day.

Regards, Tony Day. tonyd@melb.alexia.net.au - -----Original Message----- From: FRACPER@aol.com [SMTP:FRACPER@aol.com] Sent: Sunday, 31 August 1997 21:52 To: Fractint@xmission.com Subject: (fractint) Let me introduce myself Last week I sent the following letter to the members of "fractal-art". 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.

A M Kelley wrote: > > Hi Ed....what I want is a .frm file that has the default fractint fractal > types' formulas so that I can read them in a text editor. Hi Alice: It's me again. The default Fractint formulas are not in any default formula file at all. When Fractint was compiled from the C language to the .exe file, the formulas of which you inquire were written into the source code. That is why you can see lambdafn, z(0), and z(n+1) in the formula description box when you look at the nearly 100 default formulas that came with Fractint. What I now think you want is some way to translate the lambdafn fractal type that came with Fractint to a .frm file that would create the same image, but using those terms that are allowable under the *Predefined Variables* and *Precedence* paragraphs I cited in earlie messages. Reiterating, you won't be able to use z(0) or z(n+1) in the formula file you want to write because, although it was hardcoded into the program, the user has to write her formulas in a different manner as outlined in those paragraphs I mentioned. And, lambda was not included in the user- allowed terms in those paragraphs either. What Sylvie did was to rename P1 as lambda in the initialization part of her formula, then instead of writing P1 * z, or whatever the equation was--I don't have it handy at the moment--she wrote lambda * z. Therefore, for lambda, you would be asked to enter real and imaginary numbers for lambda at P1. I hope I'm making myself clear, but if not, here's some more info from the out-of-print book Fractal Creations, 2nd Edition, by The Honorable Tim Wegner and his trusty companion Bert Tyler, which was written for users of Fractint 18. Pages 282-283... Lambdafn Category Mandelbrot/Julia Generalized This type is the Julia variant corresponding to fractal type mandelfn, and is the generalization of type lambda. Formula: Initialize: z=pixel Iterate: cfn(z), where fn(z) is one of conj, cos, cosh, cosxx, cotan, cotanh, exp, flip, ident, log, recip, sin, sinh, sqr, tan, tanh, or zero. Code: Routine Type Routine Name File Fractal engine StandardFractal() CALCFRACT.C Integer math initialization long_julia_per_pixel() FRACTALS.C Integer math orbit LambdaTrigFractal() FRACTALS.C Floating point initialization otherjuliafp_per_pixel() FRACTALS.C Floating point orbit LambdafpFractal() FRACTALS.C So, as I said, the lambdafn formula was written into the C-language files that were compiled to make Fractint. You won't find it in any default formula file. You'll just have to regard it as the *sacrificial lambda*. 8-) Now I'm going back to watch the rest of Monday Night Football.

Hi Alice, You wrote > what I want is a .frm file that has the default fractint fractal types' formulas so that I can read them in a text editor. Sylvie directed me to a possible source of some of them in Orgform, but I was unable to locate them. < Repeating a bit what has already been said here, if you select the type and then hit you will see a brief explanation of the built in type. Also hitting F1 in the menu selection screen will show the documentation's explanation of the type. The idea of writing formulas for the type "formula" feature of fractint which are equivalent to the built in types has been posed as a challenge to Fractint users several times over the years. It turns out that some are easy to do, and others quite difficult. Formulas which were written in answer to these challenges generally have the same name as the built in type, and were collected in .frm files with the names Sylvie mentioned (builtn.frm, builtn01.frm, and builtn2.frm; I think there also may have been a file "parser.frm" which did the same thing). To see the built in type "lambdafn", for example, you would look in the orgform compilation files _l.frm and _l_dup.frm for formulas with the name "lambdafn". Hitting F2 while the formula name is highlighted in the menu selection screen will show you the text of the formula. You probably have someone's stab at casting the built in type as a formula. If there is no formula in the compilation with the same name as the built in type, it means that no one has yet written a formula equivalent of the built in type. You can collect all of the formulas in the orgform compilation which have a common source into a single .frm file by using the /r switch. For example, the following command orgform builtn.frm /r will cause orgform to search the entire compilation, and copy any formula with a line ";SOURCE: builtn.frm" to a file reconstr.frm (successive runs with this switch append the formulas to reconstr.frm, so you can collect the formulas from several sources into this one file). A big caveat is necessary here - the reconstructed file may not have all the formulas that the original file had. This happens when a formula from a file was not added to the orgform compilation because an identical version of the formula was already in the compilation from another source. Also, inter formula text is not copied into the orgform compilation, and will therefore also will be missing from the reconstr.frm reconstruction of the file.
