glutSolidSphere(GLdouble radius, GLint slices, GLint stacks);
The number of divisions around the z axis. (latitudal)
The number of divisions along the z axis. (longitudal)
The glutSolidSphere() function draws a shaded sphere centered at the origin. The surface is created from quadrangles (except for triangles as degenerate quads at the poles) in a longitude/latitude pattern. The equatorial great circle lies in the xy-plane and is centered on the origin.
The number of polygons representing the spherical surface is proportional to (slices*stacks).
