WebOpenGL Shading Language (GLSL) is a high-level shading language with a syntax based on the C programming language. It was created by the OpenGL ARB (OpenGL Architecture … WebFirst we will focus on the syntax of GLSL and the operations used. 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.
