OpenGL is a powerful software interface used to produce high-quality, computer- generated images and interactive applications using 2D and 3D objects and color bitmaps and images.

The OpenGL Programming Guide, Fourth Edition, provides definitive and comprehensive information on OpenGL and the OpenGL Utility Library. The previous edition covered OpenGL through version 1.2. This fourth edition of the best-selling guide describes all of the latest features of OpenGL versions 1.3 and 1.4, as well as the important OpenGL Architecture Review Board (ARB) extensions.

You will find clear explanations of OpenGL functionality and many basic computer graphics techniques, such as building and rendering 3D models; interactively viewing objects from different perspective points; and using shading, lighting, and texturing effects for greater realism. In addition, this book provides in-depth coverage of advanced techniques, including texture mapping, antialiasing, fog and atmospheric effects, NURBS, image processing, and more. The text also explores other key topics such as enhancing performance, OpenGL extensions, and cross-platform techniques.

This fourth edition has been extensively updated to include the newest features of OpenGL, versions 1.3 and 1.4, including:

Cube-mapped texture mapping

Multitexturing

Multisampled antialiasing

Depth texturing and shadows

Advanced texture application modes

Many new example programs have been incorporated as well.
