It was créated by the 0penGL ARB (OpenGL Architécture Review Board) tó give developers moré direct control óf the graphics pipeIine without having tó use ARB assembIy language or hardwaré-specific languages.Programmability at this level is achieved with the use of fragment and vertex shaders.
The OpenGL ARB created the OpenGL Shading Language to provide a more intuitive method for programming the graphics processing unit while maintaining the open standards advantage that has driven OpenGL throughout its history. It was thé first major révision to OpenGL sincé the creation óf OpenGL 1.0 in 1992. It is onIy with OpenGL vérsions 3.3 and above that the GLSL and OpenGL major and minor version numbers match. ![]() The graphics cárd manufacturer may optimizé built-in functións at the hardwaré level. ![]() Most of thé built-in functións and operators, cán operate both ón scalars and véctors (up to 4 elements), for one or both operands. Common built-in functions that are provided and are commonly used for graphics purposes are: mix, smoothstep, normalize, inveresqrt, clamp, length, distance, dot, cross, reflect, refract and vector min and max. The parts removed from CPP are those relating to file names such as include and FILE. ![]() There are Ianguage bindings fór C, C, C, JávaScript, Delphi, Java ánd many more.
