GLSL (OpenGL Shading Language)

GLSL, or OpenGL Shading Language, is a programming language designed for graphics programming in computer graphics. It's used primarily to write shaders, which are small programs that run on the GPU (graphics processing unit) to control how 3D models are rendered on the screen. With GLSL, developers can create effects like lighting, shadows, and textures, enhancing visual realism in video games and simulations. Essentially, it allows for powerful customization of how graphics are displayed, enabling richer and more dynamic visual experiences.
