part 15926 (eye ball)

[Philippe Hurbain]

Adding normals to loose triangles/quads isn't going to help, besides those are extremely easy to calculate on demand.

Are they? I think that part of the problem comes from surfaces in pattern laying on flat surfaces (triangles of the relatively low resolution 4-8sphe). If each of those tiny surfaces got normals on each vertex from mathematical sphere and shading derived from that, overal result would be smoother?
