WebJul 6, 2024 · The Phong reflection model in particular describes the light reflected from surfaces or emitted by light sources as the combination of 3 components: diffuse, ambient and specular. The model also requires information about the direction in which a particular surface is facing, provided via vectors called surface normals. WebApr 3, 2024 · 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. Fortunately, it's not all that hard to do, and this article will cover some of the basics.
