. Someone asked, so... The fractint PAR for the buddhabrot is: Buddhabrot { reset=2004 type=mandelcloud passes=1 center-mag=-0.300522/-4.44089e-016/0.8079007/1/-90/-1.23373533611470521e-014 params=751 float=y maxiter=751 fillcolor=0 inside=0 outside=summ sound=off colors=200A84<20>oiPqjQslR<3>zsW<25>CB6A95874653442220000400<23>o00q00s00<3>z00<25>C00A00800<3>000<2>554776998BBACCB<18>\ iihjjillk<3>ssr<25>BBA998776<2>221000011<24>0bn0cp0er<3>0ky<25>09B089067<2>021000210<2>863 } The colors were saved out as a map, and referenced in sstools.ini. Thus it is simpler: Buddhabrot_ { reset=2004 type=mandelcloud passes=1 center-mag=-0.300522/-4.44089e-016/0.8079007/1/-90/-1.23373533611470521e-014 params=751 float=y maxiter=751 fillcolor=0 inside=0 outside=summ sound=off } A BASIC script prints out the whole thing as a literal string, but the params and maxiter numbers are variables; a simple loop varies them from 2->751 and prints out all the PAR entries to one file, along with a BAT file which runs fractint and references the entries sequentially. XFRACTINT? I tried it a few years ago when I was investigating linux. It didn't seem to be as fast or as versatile as DOS fractint so I shelved it. I'm still waiting for 64 bit Fractint ... In the mean time, I've finally got ultrafractal to read some of my fractint pars, like for the universe sequences, but I have to hack them up a bit. Maybe I can re-render the U3 viddie in 32 bit color if I can get it right. But I don't know if current systems can be run 24/7/365; they are not as robust as older systems and tend to overheat. I can fix that, but the rendering time should be much quicker since a windows app can take advantage of the full proc capabilities and 32 bit memory addressing, but they actually render slower than fractint. Don't know why that is ... JoTz .

FractInt for Windows (beta 4) -- open for testing
by Richard 13 Aug '07

13 Aug '07

Welcome to the FractInt Makeover! For those of you on the fractint list that may not have heard, I've been overhauling the FractInt source base to move it out of the 16-bit DOS world. Things have been progressing nicely and I'm now at a point where I think widespread testing would be helpful. Download and install beta 4 of FractInt for Windows: <http://tinyurl.com/26dvd7> I've just resubscribed to the fractint list so you can send bug reports to me or to the list. If you have any doubt, just send any bugs to me. A memory dump file will be produced upon a crash, but that shouldn't be happening anymore :-). This is what I would call "Phase I" of the overhaul. It is a migration of the existing DOS source base to a 32-bit Windows application. The user interface looks and acts like DOS because it is just a port of the DOS ui. A minimal amount of "Windows-ification" has been done, but you'll notice a lack of normal Windows things like a menu bar, context menu, paying attention to the mouse, dialog boxes, etc. The next phase will be to backfill these changes into the X Window System version to make all these features available to xfractint. Once that is tested, the beta will be over and a new release made. Known Issues There is no sound output support. There is no mouse support. Panning and zooming is by keyboard only. Video modes with pixel dimensions other than 4/3 aspect ratio assume non-square pixels. The images all render fine, but they appear stretched or squashed. The choice of resolutions in fractint.cfg reflect this. With debugflag=10000, error messages are reported for disk video mode when: start fractint, pick any disk video mode (e.g. 320x200), let it render, wait for completion, then go to the <v> screen, change 320 to 32, submit it. Without the debugflag settings, FractInt for Windows will most likely crash. This problem is present in the DOS fractint and not a result of the port. There are a few gaps in functionality associated with fractal types that were computed via assembly language, but these were mostly integer versions of some of the more common fractal types. If you encounter this situation a message will be displayed informing you that you should switch to floating-point for a useful image. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Here's three more .pars from my archives, with .frm. ..20 uses the same formula as ..19, but will send it again in case someone didn't get it with the ..19 post. ..21 & ..22 use the same formula (sqr(1/fn)) which is part of the basic package and should be available if you have the basic program files.

Fractint for Windows (beta 5)
by Richard 27 Feb '07

27 Feb '07

This is the current beta; beta 4 is no longer available. FractInt for Windows (Beta 5) <http://tinyurl.com/2wqa7r> You can uninstall beta 4 or you can install beta 5 over top of beta 4. If you install over top, beta 4 will be upgraded to beta 5. This fixes all the issues reported earlier with the exception of the history buffer. It appears to reset parameters to their default for the fractal instead of the history buffer parameters, so there is still something going on there... -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Fractint (DOS) and Windows Vista
by Sylvie Gallet 25 Feb '07

25 Feb '07

Hi All, I just got a new computer with Windows Vista Home Premium and I'm still in the process of customizing it and installing my favorite softs. Bad news: Fractint for DOS won't run, all I get is an error msg saying "This system does not support fullscreen mode. Choose 'Close'to terminate the application." Cheers, - Sylvie

Well, maybe now that the dust has settled, I can sneak this stuff in on the list. I will try to paste directly into this sending rather than attach as I have done.

autokey/par files best for bug reports!
by Richard 22 Feb '07

22 Feb '07

Hi gang, I know that we're making these nifty little crash dumps now, but sometimes I don't get anything useful from them. If you can make par files or autokey files that reproduce your bugs in the current betas of FractInt for Windows, that would make things much easier for me! It also helps me build a pile of files I can use for regression testing, so it not only helps with your existing bug it helps for every single release. Keep those bug reports coming! Beta 6 will most likely be released this weekend and will contain a fix for the skewing introduced on rotated zoom boxes. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

FOTD hiatus
by Jim Muth 20 Feb '07

20 Feb '07

Fractal visionaries and enthusiasts: With the release of the beta 4 and 5 versions of Fractint for windows, the list will be plenty busy for a while. I'll take a break in the FOTD and use the opportunity to get caught up in the regular work that has been piling up here at Fractal Central. It might be a few weeks before I can get back to the FOTD, but fear not. The FOTD will return when things calm down. Meanwhile, lets get those bugs out of Fractint for Windows. This upgrade has been badly needed for quite some time. Jim Muth

Re: Buddhabrot

. It does not seem possible to zoom-in to the buddhabrot in the usual way, which makes sense if you think about what's going on. That sucks, and like most things that suck ain't much I can do about it. However, varying the parameter and iteration count yields an interesting morphing evolution effect: http://www.fractal-animation.net/vid/buddhabrot.zip 45 sec 640x480 WMV 9.1 MEG Cheers JoTz .

. Ok, I will give it a spin; see if I can render animations faster now in 32 bit WinDoZe. As an "amateur" coder myself, I can appreciate what you are doing. Thanx! BTW, as a Libertarian I think EVERYTHING should be legalized <g> Cheers JoTz .
