Paul?
by Richard 20 Nov '09

20 Nov '09

Hey, did Paul get CVS access? Paul, were you able to compile the branch with VC++ 2005 Express? I did put some tweaks in there to get everything to compile with no warnings on the Express edition. I haven't put a copy of VS.NET 2003 Academic Edition in the mail for you yet, but its coming... -- "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/>

Athlon woes
by Tim Wegner 03 Sep '08

03 Sep '08

I built a computer last year using an Athlon with a Gigabyte motherboard. I had troubles with Fractint - with any SVGA mode the computer would hang after the completion of the image. I always assumed this was an Windows XP issue. Today I tried Fractint with freedos on the same computer, with the same results. So apparently it's an incompatability bgetween fractint and my compuiter. Truecolor, 320x200, diskvideo, and even tweaked modes work. SCGA modes fail, and only after the image completes. This behavior appears to have nothing to do with recent versions. Has anyone else had trouble with Athlon? Hmm, maybe I need to look at bios settings. Tim

PNG fRAC chunk (was [Fractdev] 6-bit to 8-bit color channels )
by Tim Wegner 25 Sep '07

Rich wrote: > I guess I'll have to wait until you expound upon this later, > though. My original idea (in broad terms) was this. 1. Define a number of "subchunks" for fRAc, and treat them a lot like PNG treats chunks, but inside fRAc. I doubt sunchunk is an official PNG idea, so we'd need to extend the PNG API for fRAc purposes. 2. Define separate subchunks for obvious data items like corners or center mag. As much as possible make these universal so other fractal programs could use them (not that we're going to drive what other prograns do any more). 3. Then there are bound to be other fractint-specific items, maybe a lot of them, that we can't avoid. Figure out how to deal with them. Maybe fRAc, or at least parts of fRAc, will be "Stone Soup" spefcific. This is just a start. No big rush because the GIF extension facility will work fine for a while. Tim

6-bit to 8-bit color channels
by Richard 27 May '07

27 May '07

I think I've identified all the portions of the code that assumed 6-bit color channels. Are there any gotchas I should look out for in order to change the code to support 8-bit color channels? -- "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/>

resume of worklist
by Richard 26 May '07

26 May '07

Why does the code allocate sizeof(worklist)+20 in alloc_resume and then put_resume on the worklist and the count? What's the point of the +20? -- "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/>

Patch 5 to Fractint version 20.4
by Jonathan Osuch 26 May '07

26 May '07

Patch 5 to Fractint version 20.4 is now available on the Fractint Developer's web sites: www.fractint.org or www.fractint.net This is unrelated to Rich's port. What's new: Changed help screen to show just two main authors - decided better not to show inactive authors. Added commented out bf version of Mandelbrot in fractalp.c. Giving thought to offering bfmath as an option to bnmath, but if we fix the current bignum problems, this may be moot. Added interation to <tab> screen. Fixed the logic for calculating when to switch from using a grid to using the on-the-fly calculation of an image's pixels. The logic was not handling disk video images sized above 2048x2048 with floating point enabled. Added the savename to the disk video status screen. Fixed bug in the compare routine of bn_math that fixes long standing problem with periodicity checking in deep zoomed images. Added code to force periodicity=0 when the inside=atan feature is used.

[...] Good point, but there's a question about whether or not the par file constitutes a "work" I suppose.

extras: all_maps, frmtut, if_else, phctutor
by Richard 25 May '07

25 May '07

Why are these tossed into a separate folder instead of: - all_maps.zip -- .map files included in maps folder in distribution - frmtut, if_else, phctutor -- included in on-line help documentation Is it the copyright that's holding us back from integrating these items instead of leaving them orphaned in the extra folder? -- "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/>

philofractal
by Richard 24 May '07

24 May '07

Given that the only things I've been seeing on this list are duplicate postings of Jim Muth's FOTDs, I've just unsubscribed. When there is a new beta, I'd appreciate it if someone else would forward the message to that list, if you think its worthwhile. Given that nothing significant has happened to fractint for a long time, both philofractal and the fractint list seem relatively dead. I imagine that all the activity is happening on lists dedicated to UF or elsewhere. Sci.fractals has also been effectively dead for a long time. I got tired of reminding Roger Bagula that the newsgroup isn't his personal blog and gave up. -- "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/>

Boost & Octonions
by Richard 23 May '07

23 May '07

Check out the libraries available via Boost. <http://www.boost.org> These have the right licensing for inclusing in FractInt. In particular, the Octonion library (8-d extension of Quaternion) looks interesting in that there are probably some funky fractals lurking in 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/>
