Notes:

Noise is a fundamental building block for generating interesting textures procedurally. Noise can be used to map colors, generate bump maps, serve as offsets for other texture patterns, and more! So having a good understanding and insight into how to generate noise is very important. In this shader, I explain just how to do that!
