Summary

Description
Deutsch: Stereografische Projektion als Inversion einer Kugel
English: Stereographic projection as an inversion of a sphere. A stereographic projection usually projects a sphere from a point (north pole) of the sphere onto the tangent plane at the opposite point (south pole). This mapping can be performed by an inversion of the sphere onto its tangent plane. If the sphere (to be projected) has the equation (alternately written ; center , radius , green in the picture), then it will be mapped by the inversion at the unit sphere (red) onto the tangent plane at point . The lines through the center of inversion (point ) are mapped onto themselves. They are the projection lines of the stereographic projection.
