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… WebSpecializing in full stack development for interactive apps, design, software engineering, and motion graphics since 1998. howard adcock memphis tn

WebJul 15, 2010 · Phong shading uses Lambertian reflectance to model diffuse reflection, taking the dot product of the surface normal and the direction from the surface to the light source. If the dot product is greater than zero, it is multiplied by the diffuse color of the light, and the result is multiplied with the surface diffuse color to get the shaded result.
