Diffusely convolved cube map

From Tech Artists Wiki

Jump to: navigation, search

A diffusely convolved cube map is a cube map that has been blurred so that it represents the diffuse lighting coming from the cube map environment. Whereas a normal cubemap is used for reflection and specular lighting, a diffusely convolved cubemap can be used for ambient or diffuse lighting, to simulate global illumination.

Diffusely convolved cube maps are created from normal cube maps using ATI's CubeMapGen.
