Please tell me what the benefit is of your even distribution of triangles
over the currend distribution whith 9 quads and 4 triangles? To my opinion,
this factor alone doesn't seem to result into any severe deformations in
renderings with Ldraw and L3Lab, and the old primitive uses a smaller number
of faces. I remind you that for POV renderings, the program L3P substitutes
this primitive with a real sphere segment.

| I started a discussion on the .dev group regarding sphere tesselation a little while back, and it came out that there is some dissatisfaction with the current sphere primitive. I have finished the code which generates a replacement sphere primitive, (...) (26 years ago, 21-Sep-00, to lugnet.cad.dat.parts.primitives)
