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. WebNov 1, 2024 · Phong Lighting.
