Abstract

We analyze the energy balance of Ward’s empirical reflection model and calculate the distribution of Ward’s Monte-Carlo importance sampling used in the Radiance Lighting Simulation and Rendering System. Both results suggest a different normalization of the bidirectional reflection distribution function proposed by Ward.
