The Blinn–Phong reflection model, also called the modified Phong reflection model, is a modification developed by Jim Blinn to the Phong reflection model. Blinn–Phong is the default shading model used in OpenGL and Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each … See more In Phong shading, one must continually recalculate the dot product $${\displaystyle R\cdot V}$$ between a viewer (V) and the beam from a light-source (L) reflected (R) on a surface. If, instead, one … See more High-Level Shading Language code sample This sample in High-Level Shading Language is a method of determining the diffuse and specular light from a point light.
