Realistic image generation is presented in a theoretical formulation that builds from previous work on the rendering equation. Previous and new solution techniques for the global illumination are discussed in the context of this formulation. The physical rules governing reflection are used to make improvements in local reflection models. The conventional local illumination models used in computer graphics are examined and modified to be consistent with these physical rules. Global… CONTINUE READING
