"WebThe Phong shading can also include a Fresnel term in order to heavily favor rim lighting cases as opposed to general specular highlights. Under very bright lights, the specular rim highlights are often bright enough to bloom out in a dramatic fashion as a result of the Source engine's normal HDR post-processing.

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.
