The plane can either intersect the sphere, … WebNormally, to unwrap a sphere, view the sphere with the poles at the top and bottom. After unwrapping, Blender will give you an equirectangular projection; the point at the equator facing you will be in the middle of the image. A polar view will give a very different but common projection map.

We have already been studying one of the most useful mapping techniques, central projection from a viewing point to a horizontal plane.

WebMar 13, 2015 · Basically you want to construct a line going through the spheres centre and the point. Then you intersect this line with the sphere and you have your projection point.
