Computer Graphics Learning

However, Phong shading was still rarely used in PC gaming after that because it was computationally expensive. All points over the surface of the polygon are then displayed with the same intensity value. Lighting Models.Illumination refers to the math and algorithms necessary to compute the effect of light on a single point in the scene; shading deals with techniques that extend the effect of . Phong Shading was developed at the University of Utah, by Phong Bui Tuong and was first published in 1973.837, notably Fredo Durand and Barbara Cutler. Then vertex shaders were invented, but they don’t actually . It is interested in the entire process of . Shading model is used to compute .
