Ray Tracing for Global Illumination

Nelson Max

This course covers techniques for realistic computer graphics rendering that consider global illumination, that is, light from light sources bouncing multiple times on object surfaces in the scene before illuminating the surface being shaded. The radiosity method is briefly discussed, but most of the course is spent on recursive stochastic ray tracing, which uses Monte Carlo integration to estimate the multidimensional integrals involved in global illumination. Topics covered include direct …
