Detailed Description

precompute prefilter texture used in physically based rendering

Prefilter texture is a cubemap result of integration of the input cubemap contribution in BRDF equation. The result depends on roughness coefficient so several levels of mipmap are used to store results of different roughness coefficients. It is used in Image Base Lighting to compute the specular part.
