The shaders we will make are mostly implementations of simple algorithms. In the next chapter, “Advanced Shaders,” we will focus on more complex algorithms, so knowing the basic GLSL syntax and the use of operations will serve as a pre-requisite for that chapter.

WebOpenGL Shading Language (GLSL) is a high-level shading language with a syntax based on the C programming language.
