WebGLSL has most of the default basic types we know from languages like C: int, float, double, uint and bool. GLSL also features two container types that we'll be using a lot, namely vectors and matrices. We'll discuss matrices in a later chapter. Vectors. A vector in GLSL is a 2,3 or 4 component container for any of the basic types just mentioned. WebThe image load/store feature allows you to arbitrarily write and read from textures in a shader.
