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-dimensionalobjects. 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
program with the OpenGL graphics system to deliver the visual effect you want.

What This Guide Contains
This guide has 14 chapters, one more than the ideal number. The first five chapters present basic
information thatyou need to understand to be able to draw a properly colored and lit three-dimensional
object on the screen.
q Chapter 1, "Introduction to OpenGL," provides a glimpse into the kinds of things OpenGL can
do. It also presents a simple OpenGL program and explains essential programming details you
need to know for subsequent chapters.
q

Chapter 2, "State Management and Drawing GeometricObjects," explains how to create a
three-dimensional geometric description of an object that is eventually drawn on the screen.

q

Chapter 3, "Viewing," describes how such three-dimensional models are transformed before
being drawn onto a two-dimensional screen. You can control these transformations to show a
particular view of a model.

q

Chapter 4, "Color," describes how to specify the...
