Open Graphics Library OpenGL <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 {motion blur}. Many operations require a {frame buffer}. OpenGL is {network-transparent}, and a common extension to the {X Window System} 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}. OpenGL WWW Center (http://sgi.com/Technology/openGL/). Mesa GL (http://ssec.wisc.edu/~brianp/Mesa.html) (PD implementation). (1996-09-30)
