WebMar 15, 2016 · An easy way to change the colors across the surface of a triangle is to interpolate between the normal vectors defined at a triangle’s vertices. This is known as Phong shading and is named after its creator, Bui Tuong Phong. This lesson describes how Phong shading can be used to make triangles simulate curved surfaces. Surface Normal … 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.
