Fast Extraction of BRDFs and Material Maps from Images
(University of Waterloo, 2003)The bidirectional reflectance distribution function has a four dimensional parameter space and such high dimensionality makes it impractical to use it directly in hardware rendering. When a BRDF has no analytical ... -
Single-pass stratified importance resampling
(University of Waterloo, 2022-09-08)Simulating the behavior of light to produce realistic images involves evaluation of difficult integrals. Monte Carlo integration is a general method to estimate such integrals and is therefore widely used in physically ...
