OpenGLA (R) is a powerful software interface for graphics hardware that allows graphics programmers to produce high-quality color images of 3D objects. The functions in the OpenGL library enable programmers to build geometric models, view models interactively in 3D space, control color and lighting, manipulate images, and perform such tasks as alpha blending, antialiasing, depth cueing, and texture mapping. The OpenGLA (R) Reference Manual, Second Edition, documents all OpenGL functions, including brand new features recently approved by the OpenGL Architecture Review Board (ARB) for inclusion in OpenGL, Version 1.1. The ARB is an industry consortium responsible for defining OpenGL, composed of such industry leaders as Digital Equipment Corporation, Evans & Sutherland, Hewlett-Packard, Intel, IBM, Intergraph, Microsoft, Sun Microsystems, and Silicon Graphics. Each reference page fully describes: *C specifications *Relevant parameters *The effects of functions *Possible errors generated by functions *Associated effects Reference pages for the OpenGL Utility Library (GLU) and the OpenGL extension to the X Window System (GLX) are included in this manual.The first edition of the OpenGL Reference Manual was written by Kurt Akeley, Kevin P. Smith, Jackie Neider, and Mark Segal of Silicon Graphics, Inc.; and Sally Browning of SABL Productions. The second edition has been completely revised and updated for OpenGL, Version 1.1 , by Renate Kempf and Chris Frazier, in collaboration with the ARB. 0201461404B04062001
