From the pyglet svn: http://pyglet.googlecode.com/svn/trunk/contrib/model/model/obj.py Last revised on March 7, 2008 by Alex Holkner (revision 1884)

Additions/changes by Jim Getzen on June 2, 2008: Fixed a bug in the OBJ.load_material_library method: 'emissive' changed to 'emission'

Added a color argument to the OBJ.draw method. Added a color argument to the Mesh.draw method. Added code the Mesh.draw method to enable glColorMaterial capability (allowing objects to be temporarily recolored).

Added OBJ.compile convenience method to compile all of an OBJ's meshes.

Commented out the glDisable(GL_TEXTURE_2D) in the 'apply' method of Material. It interfered with the shadow mapping OpenGL state settings.

Note:

This is only a tiny fraction of the OBJ file format, for an idea of how much is left out, see:
