WebPhong illumination or reflection model Phong reflection is a local illumination model devised by Bui Tuong Phong and can produce a certain degree of realism in three-dimensional objects by combining three elements - diffuse, specular and ambient lighting for each considered point on a surface. WebPhong lighting model; Ambient lighting; Diffuse lighting; normal matrix; Specular lighting; Light caster directional lights. fine example of a directional light source is the sun as we know it. The sun is not infinitely far away from us, but it is so far away that we can perceive it as being infinitely far away in the lighting calculations. elimination chamber 2022 start date
