Equirectangular Projection, Gnomonic Projection, and Cubemaps

Gnomonic Projection Background According to MathWorld, the gnomonic projection is a nonconformal map projection obtained by projecting points (or ) on the surface of sphere from a sphere’s center O to point P in a plane that is tangent to a point S (Coxeter 1969, p. 93). In a gnomonic projection, great circles are mapped…
