Homomorphic factorization of BRDF-based lighting computation
Lutz Latta, Andreas Kolb · 2002
Several techniques have been developed to approximate Bidirectional Reflectance Distribution Functions (BRDF) with acceptable quality and performance for realtime applications. The recently published Homomorphic Factorization by McCool et al. is a general approximation approach that can be used with various setups and for different quality requirements.
