 Stereographic projection

Stereographic projection identifies a sphere minus one pole with the plane and supplies the standard charts of the Riemann sphere.

Stereographic projection is a method of projecting points from a sphere onto a plane. It works by projecting points from the surface of a sphere onto a plane that is tangent to the sphere at a specific point. This type of projection is commonly used in various fields, including cartography, complex analysis, and computer graphics.
