The article doesn't describe the way to avoid the difference in rectangle size in a cubesphere, so let me. The bad way: - Generate a cube - Subdivide each face using linear interpolation (lerp) - Normalize each vector to put it on a unit sphere The good way: - Generate a cube - Subdivide using spherical linear interpolation (slerp) - done! The cubesphere has lots of interesting geometric properties, particularly in texture mapping.
