Writing shaders and creating materials

A shader is a set of functions that run on the GPU. Although such functions can be applied to general-purpose computing, typically, they are used for graphics rendering—that is, to define the color of output pixels on the screen based on input that describes the lighting, geometry, surface texture, and perhaps other variables, such as time. Unity comes with many shaders for common styles of three-dimensional and two-dimensional rendering. We can also write our own shaders.

For in-depth tutorials on shader scripting in Unity, see the Unity 2018 Shaders and Effects Cookbook, by John P. Doran and Alan Zucconi (Packt Publishing, 2018).

Let's create a folder, Rollingball/Shaders, and then create a shader ...
