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