Open Graphics Library

graphics, library (OpenGL) A multi-platform software

interface to graphics hardware, supporting rendering and

imaging operations. The OpenGL interface was developed by

Silicon Graphics, who license it to other vendors.

The OpenGL graphics interface consists of several hundred

functions operating on 2D and 3D objects, supporting basic

techniques, such as modelling and smooth shading, and

advanced techniques, such as texture mapping and motionblur. Many operations require a frame buffer. OpenGL is

network-transparent, and a common extension to the X WindowSystem allows an OpenGL client to communicate across a

network with a different vendor's OpenGL server.

OpenGL is based on Silicon Graphics' proprietary IRIS GL.
