Stochastic Iteration for Non-diffuse Global Illumination
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly in each iteration. The requirements of ...
Reflectance Models with Fast Importance Sampling
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
We introduce a physically plausible mathematical model for a large class of BRDFs. The new model is as simple as the well-known Phong model, but eliminates its disadvantages. It gives a good visual approximation for many ...
Compact Metallic Reflectance Models
(Blackwell Publishers Ltd and the Eurographics Association, 1999)
The paper presents simple, physically plausible, but not physically based reflectance models for metals and other specular materials. So far there has been no metallic BRDF model that is easy to compute, suitable for fast ...
