WebApr 3, 2024 · Lighting in WebGL. As should be clear by now, WebGL doesn't have much built-in knowledge. It just runs two functions you supply — a vertex shader and a fragment shader — and expects you to write creative functions to get the results you want. In other words, if you want lighting you have to calculate it yourself.

The Phong reflection model in combination with Phong shading is an approximation of shading of objects in real life. This means that the Phong equation can relate the shading seen in a photograph with the surface normals of the visible object. Inverse refers to the wish to estimate the surface normals given a rendered image, natural or computer-made. The Phong reflection model contains many parameters, such as the surface diffuse reflection pa…
