OpenGL Programming Guide, Sixth Edition OpenGL is a powerful software interface used to produce high-quality, computergenerated images and interactive applications using 2D and 3D objects, bitmaps, and color images. The OpenGL Programming Guide, Sixth Edition, provides definitive and comprehensive information on OpenGL and OpenGL Utility Library. This text also explores other important topics such as improving performance, OpenGL extensions, and cross-platform techniques. This sixth edition has been updated to include the latest features of OpenGL, Version 2.1 include: Using server-side pixel buffer objects for fast pixel rectangle download and discussions taking sRGB texture format Expanded discussion of the OpenGL Shading Language This edition continues discussion of the OpenGL Shading Language (GLSL) and explains the mechanics of using language to create complex graphics effects and increase the computing power of OpenGL. The OpenGL Technical Library provides tutorial books and references to OpenGL. Originally developed by SGI, the Library continues to flourish under the auspices of the OpenGL Architecture Review Board (ARB) Steering Group (now part of the Khronos Group), an industry consortium that is responsible for directing the evolution of OpenGL and related technologies.
