QD3D 09 - Improper Texture Mapping with Trigrids (1-June-95)

Q Why doesn't texture mapping work properly on a sphere made of trigrids with texture applied to the whole sphere?

A For texture mapping to work, you need to add UV parameters to the vertices' attribute set.

To have smooth shading, you need to add vertex normals to the vertices' attribute set.
