WebBlinn-Phong Model. The problem with Phong, with regard to the reflection and view directions being greater than 90 degrees, can be solved by changing the computation. This modified model is called the Blinn-Phong specular model or just the Blinn specular model. It is no more physically correct than the Phong model. WebJan 28, 2016 · WebGL Implementation¶ A programmer can implement any of these techniques in their shader programs. One normal vector per face and one normal vector per vertex are implemented in vertex shaders. Phong shading and bump maps are implemented in fragment shaders because they calculate the color of individual pixels. smart credit link

WebBlinn–Phong is the default shading model used in OpenGLand Direct3D's fixed-function pipeline (before Direct3D 10 and OpenGL 3.1), and is carried out on each vertex as it passes down the graphics pipeline; pixelvalues between vertices are interpolated by Gouraud shadingby default, rather than the more computationally-expensive Phong shading.

"WebFeb 10, 2010 · Technically ray tracing really only determines visibility and distance. Recursively it can be used for reflections, refractions, and shadows (checking light source visibility). Stochastic ray tracing or photon mapping can simulate light scattering. Phong and Gouraud shading are reflection models applied to at a surface. " - Phong shading webgl
