However as the rendering is done "behind the scenes" it can also be a software renderer as is the case with the OS/2 implementation, or both.

The basic OS/2 implementation of OpenGL was done in parallel with the [[AIX]] version of the system and shares much of the same code, this means that there is quite a lot of information pertinent to the OS/2 implementation to be found in old AIX OpenGL documentation.

OpenGL (Open Graphics Library) is a cross-language, multi-platform application programming interface (API) for rendering 2D and 3D vector graphics. The API is typically used to interact with a graphics processing unit (GPU), to achieve hardware-accelerated rendering. However as the rendering is done "behind the scenes" it can also be a software renderer as is the case with the OS/2 implementation, or both.

The basic OS/2 implementation of OpenGL was done in parallel with the AIX version of the system and shares much of the same code, this means that there is quite a lot of information pertinent to the OS/2 implementation to be found in old AIX OpenGL documentation.
