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. WebDec 11, 2024 · GLSL. A sampler is a set of GLSL variable types. Variables of one of the sampler types must be uniforms or as function parameters. Each sampler in a program represents a single texture of a particular texture type. The type of the sampler corresponds to the type of the texture that can be used by that sampler.
