What is Toon Shader?

Toon shader is a term used in 3D computer graphics for a type of shading technique that creates the illusion of two-dimensional, hand-drawn images. It is also sometimes referred to as cel shading. Toon shading is used to make 3D models and objects appear as if they were drawn or painted using traditional cartooning techniques. This can give your project a unique look and feel, and can help it stand out from other 3D visuals that use more realistic shading methods.

There are several different ways to create toon shading effects, but all of them involve using some combination of simplified lighting and shadowing algorithms, as well as cross-hatching or stippling techniques. Toon shaders can be applied to both polygonal and parametric surfaces.
