Thank you! That seems very interesting. Too bad (or good?) you didn't respond earlier, as I've already bothered to come up with a triangulation technique that also works quite well. It starts with an icosahedron and divides each triangle into four smaller triangles during each iteration: illustration

That is wonderful. I looked into how we can make a good triangulation of a sphere surface, and found two methods below that work very well.

Needs["PolyhedronOperations`"]
Geodesate[PolyhedronData["Icosahedron"],10]
