Patch 6 to Fractint version 20.4
by Jonathan Osuch 09 Jun '07

09 Jun '07

Patch 6 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: Added Per Image Settings to the formula parser. When initially selected from the fractal type formula screen, the symmetry and any per image settings are enforced. The per image settings will be saved to PARs and GIFs, and can be changed from the appropriate screen. The possible values for per image settings are the same as the parameters that appear in PAR files, with the exception of 'params='. Params can't be set in the per image settings section, because they get set to zero when the formula is parsed. The formula syntax looks like this: mandel(symmetry)[per image settings] { per pixel settings: iteration bailout } For example: IslandOfChaos(XAXIS_NOPARM)[float=y function=sqr/sin/cosxx] {; Jonathan Osuch ; Generalized by Tobey J. E. Reed [76437,375] ; Try p1=0, p2=4, fn1=sqr, fn2=sin, fn3=cosxx ; Note: use floating point z = p1, x = 1: IF (x < 10) z=fn1(z) + pixel ELSE z=fn2(z) / fn3(z) + pixel ENDIF x = x+1, |z| <= p2 } Jonathan

Qt GUI framework -- acceptable?
by Richard 09 Jun '07

Tim, please take a look here <http://trolltech.com/products/qt/> and at the licenses here: <http://trolltech.com/products/qt/licenses/licensing/licensingoverview> The license is GPL, which implies that FractInt would also be GPL. This looks like a good GUI library that would give us cross-platform GUI support on Windows, X11, MacOS, etc. -- "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/>

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.

Re: [Fractint] Re: [Fractdev] extras: all_maps, frmtut, if_else, phctutor

[Is there some reason you redirected this to the fractint list?] In article <E1HrdBD-0001pH-Rv(a)mx01.mta.xmission.com>, dmj(a)fractalus.com writes: > Copyright doesn't protect just exact duplicates, it also protects > "derivative works". [...] Good point, but there's a question about whether or not the par file constitutes a "work" I suppose. Sometimes I think copyright is good and other times I think its lawyers gone crazy. -- "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/>

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 23 May '07

23 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/>

by Tim Wegner 21 May '07

21 May '07

Everyone has global read access via a subversion server at: http://fractint.net/fractsvn I am the only one who can commit via the server (not that I will). Those with shell accounts can access the repository (read and write) at: /home/twegner/svn/fractsvn Let me know if there are any permission problems. I have backed up but not disabled the CVS repository. Please do not commit. I'll disable it for writing as soon as it appears everything is OK. Tim
