This version loads into display lists, which are about as fast as possible for that. You won't be able to get better rendering performance. For faster *loading*, you can try Psyco, or just resort to C. > I wanted to ask if this work has already been done by anyone, or if there > is a different existing OBJ loader that could be used as a starting point.

Having searched around, I'm fairly sure that this is the simplest and best *standalone *.obj loader. However, I started with this particular loader and extensively modified it and improved it to support vertex arrays, vertex buffer objects, display lists, and fixed functionality. It also has better support for .mtl files and handles file loading and texturing more elegantly. It also calculates the tangent vectors for use in normalmapping and related techniques. It's presently integrated into glLib Reloaded<http://www.pygame.org/project-glLib+Reloaded-1326-.html>, my project, which I humbly present. The actual loader, (glLib/glLibLoadOBJ.py), is heavily tied into the rest of the library, and as such I can't support using it in other ways--but, you may find it useful. > Thanks, > Christopher > Ian
