Gnofract 4D

Gnofract 4D is Copyright 1999-2007 Tim Whidbey (catenary@users.sourceforge.net) , and is distributed under the BSD license. See the file "COPYING" for details.

Gnofract 4D was originally based on Gnofract, written by Aurelien Alleaume (manchot@club-internet.fr) , though none of the original code remains in the current version. Gnofract could once be obtained from http://www.multimania.com/mason/ but this no longer appears to work.

Branko Kokanovic developed and contributed the animation feature. Chris Le Sueur provided parts of the gradient editing feature.

The formula language which Gnofract 4D uses originated in Fractint and was substantially enhanced in UltraFractal. However the compiler implementation does not share any code with those programs.

The Gnofract 4D distribution contains palette (.map) files by a number of authors which were originally distributed with Fractint under somewhat murky licensing conditions. It also contains a copy of "standard.ucl", originally distributed with UltraFractal, by kind permission of Frederik Slijkerman, Damien Jones, and Kerry Mitchell. "blatte1.ugr" and "blatte2.ugr" are included by kind permission of 'Blatte'.

gmpy.c and gmpy.h are from the GMPY package (http://gmpy.sf.net), and are distributed under the LGPL license.

lex.py and yacc.py come from the PLY package, and are distributed under the LGPL license.

The man page was contributed by Aleksander Adamowski.
