RE: [PyOpenGL-Users] Lighting and texturing

[Mike C. F. <mcf...@ho...>]

Just a note, beyond just enabling blending, you normally want to sort the
triangles from farthest to nearest for rendering.  The
OpenGLContext/scenegraph/arraygeometry classes (and some supporting modules)
do that if you need sample code.  It's not fancy (no resolution of
equi-distant interfering geometry, for instance, no tessellation where
triangles intersect for another), but it can avoid having some of the
artefacts.

Enjoy,
Mike

Actually, the image is fine... I just got the alpha stuff going - the
GL_BLEND isn't the TexEnv, it's just something that needs glEnable'ing.
Fixed!
