Abstract :
A tutorial that presents a technical-level chronology of illumination model development is provided. The basic techniques and capabilities of certain algorithms that changed the direction of computer graphics research are described. Included are treatments of Lambertian (constant) shading, Gouraud shading, Phong shading, the Torrence-Sparrow illumination model, Whitted´s original ray-tracing based illumination model, and interreflections between diffuse surfaces (radiosity)
