WebPhong Illumination Model • Calculate color for arbitrary point on surface • Basic inputs are material properties and l, n, v: l = vector to light source n = surface normal v = vector to viewer r = reflection of l at p (determined by l and n) Basic Calculation • Calculate each primary color separately • Start with global ambient light WebJul 20, 2016 · I am trying to render Blinn Phong as a BRDF model on a surface plane. I assume that every normal in every pixel is perpendicular with the plane. I know that to do a rendering we have to use 3d programing API such as OpenGL or WebGL and so on. My purpose is to render the surface plane without those APIs. The steps that I take are, I …
