 Contents
OpenGL (Open Graphics Library) is a specification defining a cross-language cross-platform API for writing applications that produce 3D computer graphics (and 2D computer graphics as well). The interface consists of about 250 different function calls which can be used to draw complex three dimensional scenes from simple primitives. It is very popular in the video games industry where it competes with Direct3D (on Microsoft Windows) (see Direct3D vs. OpenGL). OpenGL is used in CAD, virtual reality, scientific visualisation programs, information visualisation and video game development

Efficient implementations of OpenGL (leveraging graphics acceleration hardware to a greater or lesser extent) exist for Windows, many UNIX platforms, and MacOS. These implementations are generally provided by display device manufacturers and rely heavily on the hardware provided by that manufacturer. The open source library Mesa is a fully software-based graphics API which is code-compatible with OpenGL. However, for licensing reasons it claims merely to be a "very similar" API.

The OpenGL specification is overseen by the OpenGL Architecture Review Board (ARB) which was formed in 1992. The ARB consists of a set of companies with a vested interest in creating a consistent and widely available API. According to the official OpenGL website, voting members of the ARB as of JuneJune is the sixth month of the year in the Gregorian Calendar, with 30 days.
