public class GeoSphere
extends Mesh

GeoSphere - generate a polygon mesh approximating a sphere by recursive subdivision. First approximation is an octahedron; each level of refinement increases the number of polygons by a factor of 4. Shared vertices are not retained, so numerical errors may produce cracks between polygons at high subdivision levels. Initial idea and text from C-Sourcecode by Jon Leech 3/24/89
