WebSpherical reflection (or environment) mapping (SEM) is a fast way to fake the specular term of the lighting equation, and for specific cases, to fake lighting altogether. This technique has been popularised by software like … Phong reflection is an empirical model of local illumination. It describes the way a surface reflects light as a combination of the diffuse reflection of rough surfaces with the specular reflection of shiny surfaces. It is based on Phong's informal observation that shiny surfaces have small intense specular highlights, while dull surfaces have large highlights that fall off more gradually. The mode…
