There are many ways to construct a triangular mesh for a sphere. Some produce better results than others.
One can parameterize a sphere in terms of 3D polar coordinates and construct triangles from the rectanglular regions defined by sample points along the sphere.

Here is a way by Mr. IQ!
Another way is to start with a tetrahedron and subdivide (upsample) the faces and normalizing the magnitudes of all of the created positions.
Can anybody list the pros and/or cons of some of the many sphere constructing schemes and how they generate "good" / "bad" meshes in certain contexts?
