sphere_stereograph_display, a MATLAB code 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_display is available in a MATLAB version.
sphere_stereograph, a MATLAB code which computes the stereographic mapping between points on the unit sphere and points on the plane z = 1.
sphere_grid, a MATLAB code 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 code which reads a file defining a lebedev quadrature rule for the sphere and displays the point locations.
