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" ------------------------------ Date: Mon, 25 Aug 1997 10:55:16 -0600 From: Bob Norton Subject: (fractint) Matrox Millenium cards 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?

Bob: I think your problem is that NT will not run *any* DOS program in SVGA modes. I have read several messages on various newsgroups saying that NT will not run fractint (or other SVGA programs) under NT except maybe in 320x200x256 or other simple modes. I have NT 4.0 but do not use it for DOS apps. I use OS/2 for fractint. When I get home tonight I'll try running fractint under NT and let you know. Can you boot to plain DOS and try fractint? This would at least tell you if your Matrox chip is OK.

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.

I also promised to check into iterates.tga and make sure it is working OK, but I haven't done this yet. We are about to start a truecolor development effort, and I'll be looking for people who want to participate.

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.
