A similar but different idea is the TOAST projection. However here it starts with an octahedron instead of a cube. The benefit is the texture can all be stored on a square and is argued has a more uniform sampling that equirectangular projection. http://www.worldwidetelescope.org/docs/worldwidetelescopeprojectionreference.html#TOASTProjection http://www.worldwidetelescope.org/docs/worldwidetelescopepro...
