Phong reflection model - Wikipedia

WebAs a rendering method, Phong shading can be regarded as an improved version of Gouraud shading that provides a better approximation to reality by approximating the Phong … The Phong reflection model was developed by Bui Tuong Phong at the University of Utah, who published it in his 1975 Ph.D. dissertation. It was published in conjunction with a method for interpolating the calculation for each individual pixel that is rasterized from a polygonal surface model; the interpolation technique is known as Phong shading, even when it is used with a reflection model other than Phong's. Phong's methods were considered radical at the time of the… simplyhired south africa
