I am now calculating the indices a vertex is part of.

I am not sure it is _a lot_ simpler, but I believe it is geometrically clearer.

Unfortunately, the links I had looked at yesterday actually use a substantially different approach.

Specifically:
http://sol.gfxile.net/sphere/index.html
* Tessellate a tetrahedron, etc

http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/sphere_cylinder/
* Create a mesh using rectangular patches

Anyway thank you all so much for your time and I appreciate all your feedback and Henri's help with pattern recognition :)
