SPHERE_VORONOI_DISPLAY_OPENGL is a C++ program which picks random points on a sphere as generators, and then gradually colors in neighboring points according to the color of the nearest generator. This, in effect, constructs a Voronoi diagram, or at least, suggests it. The exact calculation of the boundary lines and vertices requires a more precise computation.
The user is allowed to request the number of generators, and OpenGL is used to display the results. Initially, the sphere is rotating, but at least on my machine, once I try to display the neighbors, the rotation becomes very slow.

SPHERE_VORONOI_DISPLAY_OPENGL is available in a C++ version.
FERN_OPENGL, a C++ program which uses OpenGL to display the Barnsley fractal fern.
ROTATING_CUBE_DISPLAY_OPENGL, a C++ program which displays a rotating color cube in 3D, using OpenGL;
SPHERE_CVT, a FORTRAN90 library which creates a mesh of well-separated points on a unit sphere using Centroidal Voronoi Tessellations.
SPHERE_CVT, a MATLAB library which creates a mesh of well-separated points on a unit sphere by applying the Centroidal Voronoi Tessellation (CVT) iteration.
SPHERE_DELAUNAY, a MATLAB program which computes the Delaunay triangulation of points on a sphere.
SPHERE_DESIGN_RULE, a FORTRAN90 library which returns point sets on the surface of the unit sphere, known as "designs", which can be useful for estimating integrals on the surface, among other uses.
