OpenGL represents a 3-D graphics language, initially developed by SGI (Silicon Graphics Inc). Two dialects of this language are commonly used: Microsoft OpenGL, developed for use under Windows NT, and Cosmo OpenGL made by SGI. The latter represents an independent graphics language for all platforms and all kind of computers, even usable on machines without special 3-D graphics hardware.
