WebFeb 10, 2010 · Technically ray tracing really only determines visibility and distance. Recursively it can be used for reflections, refractions, and shadows (checking light source visibility). Stochastic ray tracing or photon mapping can simulate light scattering. Phong and Gouraud shading are reflection models applied to at a surface. WebPhong is a basic shader that is very similar to Cook-Torr, but is better for skin and organic surfaces. Bui Tuong Phong (1942-1975) was a Vietnamese-born computer graphics pioneer that developed the first …
