OpenGL (Open Graphics Library) is a software interface to graphics hardware. The interface consists of a set of several hundred procedures and functions that allow the programmer to specify the objects and operations involved in producing high-quality graphical images, specifically color images of three-dimensional objects. Most of OpenGL require the graphics hardware to contain a frame buffer. Much of OpenGL instructions pertain to drawing objects such as points, lines, polygons, and bitmaps and the drawing of these objects rely on the existence of a frame buffer. |
