WebCook-Torrance Reflectance Model. In 1982, Robert Cook and Kenneth Torrance published a reflectance model that more accurately represented the physical reality of light reflectance than the Phong and Blinn-Phong models. The proposed method is general purpose - it has three “pluggable” components that can be replaced with equations of … WebBlinn-Phong Phong lighting is a great and very efficient approximation of lighting, but its specular reflections break down in certain conditions, specifically when the shininess property is low resulting in a large (rough) …

WebBlinn-Phong 光照模型，又称为 Blinn-phong 反射模型 （Blinn–Phong reflection model） 或者 phong 修正模型 （modified Phong reflection model） ，是由 Jim Blinn 于 1977 … 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 … 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. The light structure, position in space of the surface, view … See more Blinn-Phong will be faster than Phong in the case where the viewer and light are treated to be very remote, such as approaching or at infinity. This is the case for directional lights and orthographic/isometric cameras. In this case, the halfway … See more • List of common shading algorithms • Phong reflection model for Phong's corresponding model See more new sota
