Found some refernces to create a 3D Texturs lightmap? I'm tying to create a disco ball and found sime references to an example from the SIGGRAPH conferences but can't find the file anywhere. :-( (lightmap3d.c) Thanks for any help guys... -Adam

A bit of a hack:
You could try to spheremap a sphere. The trick is to make the face normals ortho to each of the triangles (an easy way to do this is cross product at load time). The only problem with this approach is that you dont get the rays eminating from the ball (it just looks like a reflection). If you want the rays, you could draw the ball several times at increasing scale with reduced alpha (kinda like fins and shells).
