Title:

Homomorphic Factorization of BRDFs for High-Performance Rendering
 

Abstract:

A 4D bidirectional reflectance distribution function (BRDF) describes how a material reflects light from its surface. To use arbitrary BRDFs in real-time rendering, a compression technique must be used that can represent the BRDF using the available texture-mapping and computational capabilities of an accelerated graphics pipeline. I will present a numerical technique, homomorphic factorization, that can decompose an arbitrary BRDF into a product of two or more 2D factors, each factor dependent on a different interpolated geometric parameter. This research stems from work by Michael McCool, Anis Ahmad, and me.
