Sphere Map

Sphere maps are special textures that contain an image of the scene surrounding an object, or the lighting effects around the object. Unlike cubic environment maps, sphere maps don't directly represent an object's surroundings. A sphere map is a 2-D representation of the full 360-degree view of the scene surrounding of an object, as if taken through a fish-eye lens, see the following illustration:

There are three shader files for sphere map in Awakening's effects\spheremap folder: Spheremap.sha, SpheremapDiffuse.sha, SpheremapTexAlphaBlend.sha.
