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. Hope these instructions are helpful to you.

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 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 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.

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... - -- .*.

If you think about it, you will realize that if fractint allowed the existing values of variables to affect a PAR, that you'd never get the effect the PAR author intended. So "reset" puts variables back to their initial default values. The "=" part is a version number, so that to the extent that fractint supports backwards compatibility for a specific feature that is changed, a PAR will render the same with later Fractint versions.

I don't think the "disks" algorithm is such an important feature to have (although it's great work by Yuval Fisher), since you only get a b&w image and I don't believe it's significantly faster than a boundary trace. Now, if you want to take Mandelbrot set drawing to the next level, IMHO you'll need component detection based on the work by Jay R. Hill in "The Future Use of Fractals" (Jay, I have finally received a copy of the book and I'll mail you soon about it). It's a far more advanced version of the inside disks algorithm described in "The Science of Fractal Images" (which, IMO, is infeasible to implement). Good luck, - -- Michael R. Ganss Cooper: Look!

As for component detection, I was already planning to have the basic Mandel formula blast both the cardioid and the biggest disk automatically. That would really speed up exploration of SH valley and elephant valley, two favored watering holes of fractal lovers everywhere. You seem to refer here to a generalized component detection. It sounds like this is meant to spot circles and cardioids anywhere. How would it work? I considered such a thing myself once. Once. It seemed infeasible, as to get components of period n requires accurately finding the roots of big polynomials... order 2^n I believe. If you know the center and radius of a circle, or the cusp point and opposite point of a cardioid, you can calculate away the whole thing and floodfill it. Another approach would be to spot the components other ways, but I can't think of one that isn't lossy. For example, draw a series of vertical lines down the image from points at the top. Stop each when it hits an inside point. What is the result? These points may be part of a circular arc that can be used to infer the circle. But the fractured landscapes of some complex formula types and the "perturbed" M-set (z_0 not critical) would "fool" it. And how to differentiate a cardioid, so as to at least ignore it? - -- .*.

I am new to the list, but a long time user of Fractint. I run a 233mhz PentII at home, and an SGI Onyx at work. I do image compositing to buy food using software called Flame. This setup makes it possible for me to easily create animations without all that tedious mpegging and avi'ing. My finished work is at digital video resolution. Another one of my favorite pieces of software is FAE which I use to create the .bat files for my projects. If any of you have any snappy .fae files worth rendering, I'd love to share some with you.
