this article is to analyze the things behind the Surface Shader! That is, to analyze how the Surface Shader parses the functions such as surf and LightingXXX, and how to obtain the pixel color. So, let's get started!
Assembly Line
First, we need to understand what features Surface Shader supports. For more information, see the official website.
The most important part of Surface Shader is

magic. As the name suggests, it is the content related to learning vertices. Since reading a figure in Unity gems below, I have a better understanding of the entire surface shader workflow. I will repeat it here.
We can see that there are four stages that we can participate in. Most of our previous studies were in the second and third stages, namely writing the surf and lightingxxx functions to influence the surface coloring and illumination funct

It is complicated to use shader to implement illumination. There are different light types, different shadow options, and different render paths (forward and deferred ). Unity only encapsulates the illumination model, and the shader code is written by CG/HLSL.

enough, the dog's value will be affected by the edge, the points on the edge, although not the spots, but its dog response is also strong. So we're going to remove this part of the point. We use the area across the edge to exhibit the greatest and smallest principal curvature along the edge and the vertical edge direction. So by calculating the ratio of the principal curvature at the feature point, we can distinguish whether it is on the edge. This point can be found in the interpretation of th
