[GLSL] What is a shader? https://thebookofshaders.com/01/ The Book of Shaders Gentle step-by-step guide through the abstract and complex universe of Fragment Shaders. thebookofshaders.com Shaders are also a set of instructions, but the instructions are executed all at once for every single pixel on the screen. That means the code you write has to behave differently depending on the position of the pixel on the screen. L.. 2022. 1. 5. [GLSL] Let's Dive in to the Shader!
