This document talks about some knowledge related to shaders in Unity3D; in shader programming, there are some terms that are sometimes confusing if you don’t understand them, so I will briefly mention them here. Shading originally refers to painting objects with light and dark tones in sketches. In graphics, it actually means coloring Mesh (Mesh is a bunch of triangular patches, including the left side of the vertex, normal coordinates, UV coordinates, etc.), wiki What is mentioned in is the process of changing the color of an object to generate a photorealistic effect based on the angle of the object relative to the light and its distance from the light source. The program we write to process shading is called shader, which is called shader in Chinese. The input of the program is color, texture, coordinates, etc., and the output is the final color of the mesh grid. Friends in need can download and take a look
