(OpenGL) A multi-platform
software interface to graphics hardware, supporting rendering
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).
