introduction

The OpenGL interface consists of a set of commands that allow applications to define and manipulate three-dimensional objects. The commands include:

•Geometric primitive definitions

•Viewing operations

•Lighting specifications

•Primitive attributes

•Pipeline control

•Rasterization control

OpenGL has been implemented on a large number of vendor platforms where the graphics hardware supports a wide range of capabilities (for example, frame buffer only devices, fully accelerated devices, devices without frame buffer, etc.).

For more information on OpenGL, refer to these documents, published by Addison-Wesley and shipped with HP’s implementation of OpenGL:

•OpenGL Programming Guide

Instruction on programming in OpenGL, offered in a tutorial format.

•OpenGL Reference Manual

A reference that contains details on all standard OpenGL functions, as well as utility (GLU) functions and X-windows (GLX) functions.

•OpenGL Programming for the X Window System

Instructions on interfacing OpenGL with the X Window system.
