Web11 de jan. de 2024 · The OpenGL Shading Language is a C-style language, so it covers most of the features you would expect with such a language. Control structures (for-loops, if-else statements, etc) exist in GLSL, including the switch statement. This section will not cover the entire language in detail; the GLSL specification can handle that. WebA Shader is a user-defined program designed to run on some stage of a graphics processor.
