	Compute per-vertex normals by averaging adjacent face normals.

Detailed Description

Compute per-vertex surface normals for lighting.

Surface normals are direction vectors perpendicular to the surface at each vertex. They are essential for lighting — without normals, the renderer cannot tell which way a surface is facing and cannot compute shading.
