OpenGL (Open Graphics Library) is a software interface to graphics hardware. The interface consists of over 250 different function calls which can be used to draw complex two and three-dimensional scenes from simple geometric primitives such as points, lines, and polygons.

What are the advantages of OpenGL?

OpenGL is portable. It is a cross-platform API, i.e. it can be used on various platforms such as- windows, WindowsMac, and some handheld devices. It is more extensible, i.e. new hardware features are exposed quickly. It has a stable interface until some bigger changes are made.
