GLSL(OpenGL Shading Language)

The OpenGL Shading Language (GLSL) is the principal shading language for OpenGL. While, thanks to OpenGL Extensions, there are several shading languages available for use in OpenGL, GLSL (and SPIR-V) are supported directly by OpenGL without extensions.

GLSL is a C-style language. The language has undergone a number of version changes, and it shares the deprecation model of OpenGL. The current version of GLSL is 4.60.
