The OpenGL graphics system is a software interface to graphics hardware. (The GL stands for Graphics<br>Library.) It allows you to create interactive programs that produce color images of moving<br>three-dimensional objects. With OpenGL, you can control computer-graphics technology to produce<br>realistic pictures or ones that depart from reality in imaginative ways. This guide explains how to<br>program with the OpenGL graphics system to deliver the visual effect you want.
