SPHERE_STEREOGRAPH_DISPLAY is a MATLAB program which demonstrates the stereographic projection between a sphere and a plane by displaying a set of points and their images under the mapping.
This program is primarily an auxilliary demonstration of the properties of the SPHERE_STEREOGRAPH library; it is not a standalone application, and while it can be used to understand how to compute and display stereographic projections, a considerable amount of user modifications would be needed to adapt it to each particular problem of interest.

SPHERE_STEREOGRAPH, a MATLAB library which computes the stereographic mapping between points on the unit sphere and points on the plane Z = 1.
SPHERE_GRID, a MATLAB library which provides a number of ways of generating grids of points, or of points and lines, or of points and lines and faces, over the unit sphere.
SPHERE_LEBEDEV_RULE_DISPLAY, a MATLAB program which reads a file defining a Lebedev quadrature rule for the sphere and displays the point locations.
SPHERE_VORONOI_DISPLAY_OPENGL, a C++ program which displays a sphere and randomly selected generator points, and then gradually colors in points in the sphere that are closest to each generator.
SPHERE_XYZ_DISPLAY_OPENGL, a C++ program which reads XYZ information defining points in 3D, and displays a unit sphere and the points, using OpenGL.
SPHERE_XYZF_DISPLAY, a MATLAB program which reads XYZF information defining points and faces, and displays a unit sphere, the points, and the faces, in the MATLAB graphics window. This can be used, for instance, to display Voronoi diagrams or Delaunay triangulations on the unit sphere.
