Sphere won't GL_SMOOTH shade?
Author
I have created a primitive sphere (triangle facets) and then generated vertex normals for the triangles. Lighting works perfect- but for some reason it won''t smooth shade!
Could it be a winding problem or inverted normals?
any ideas?

is glShadeModel(GL_SMOOTH);?
ensure vertex normals are created and set for each vertex.

*whew*
after some furious coding- I solved the problem. I was generating smooth vertex normals. The problem is, there were no shared vertices in the model since the triangle facets vertex data were all individual in the array.
So I added a WeldVertices() step before the GenerateNormals() and that did the trick =)
btw- welding vertices and having to update face information is a real b*****.
