GLSL

GLSL stands for Graphics Library Shading Language. It is a programming language that is used to write programs that run on the graphics processing unit (GPU). The GPU is a computer chip that processes graphics and image data. GLSL programs are used to create amazing effects in games, such as shadows, lighting, 3D models, and textures. GLSL programs can also make games run faster or look more realistic. You can think of GLSL programs like building blocks that you can use to make video games.
