Abstract:

Exitant radiance depends on lighting, visibility, and surface BRDF. With an appropriate choice of bases, we can write the joint integral of these quantities as an inner product between two terms: one that combines lighting and visibility, and another that depends on the BRDF. This factorization improves interactive editing of the BRDF and viewpoint because the reduced lighting and visibility coefficients do not need to be recomputed unless the lighting is altered.
