OpenGL Shading Language

OpenGL Shading Language (GLSL) is a programming language designed for graphics programming, primarily used to create visual effects in 3D graphics. It allows developers to write shaders, which are small programs that run on the graphics card to control how images are rendered. Shaders can manipulate how light interacts with surfaces, add special effects, and improve overall graphics quality in video games and simulations. By providing fine control over rendering processes, GLSL helps create realistic and visually appealing graphics in applications leveraging the OpenGL graphics framework.
