A Unified Manifold Framework for Efficient BRDF Sampling based on Parametric Mixture Models

Herholz, Sebastian; Elek, Oskar; Schindel, Jens; Křivánek, Jaroslav; Lensch, Hendrik P. A. (The Eurographics Association, 2018)

Virtually all existing analytic BRDF models are built from multiple functional components (e.g., Fresnel term, normal distribution function, etc.). This makes accurate importance sampling of the full model challenging, and ...
