OpenGL® (Open Graphics Library) is a cross-platform, royalty-free, open standard application programming interface (API) for 2D and 3D graphics. It is the most widely used and most widely supported graphics API, and it allows applications to target a broad range of graphics hardware, such as GPUs from AMD. The OpenGL specification is maintained and updated by the OpenGL Architectural Review Board (the ARB), which is part of the Khronos group. AMD is an active participant at the ARB and a regular contributor to the OpenGL Specification. Along with a solid specification, OpenGL includes a standard and well supported extension mechanism, allowing hardware vendors to bring acess to new features to developers quickly and efficiently.
