sphere_stereograph_display


sphere_stereograph_display, an Octave 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.
