OpenGL is a powerful software interface used to produce high-quality computer generated images and interactive graphics applications by rendering 2D and 3D geometric objects, bitmaps, and color images. Officially sanctioned by the OpenGL Architecture Review Board (ARB), the OpenGLA (R) Reference Manual, Third Edition, is the comprehensive and definitive documentation of all OpenGL functions. This third edition covers OpenGL Version 1.2, including its newest features: 3D texture mapping; multitexturing; mipmapped texture level-of-detail control; new pixel storage formats, including packed and reversed (BGRA) formats; rescaling vertex normals; and specular lighting after texturing. In addition, this book documents the newest routines in the OpenGL Utility Library (GLU 1.3) and added functionality in the OpenGL extension to the X Window System (GLX 1.3). The comprehensive reference section documents each set of related OpenGL commands.Each reference page contains: *A description of the command's parameters *The effects on rendering and the OpenGL state by the command *Examples *Errors generated by functions *References to related functions This book also includes a conceptual overview of OpenGL, a summary of commands and routines, a chapter on defined constants and associated commands, and a description of the ARB extensions, including multitexture and the imaging subset. The OpenGL Technical Library provides tutorial and reference books for OpenGL. The Library enables programmers to gain a practical understanding of OpenGL and shows them how to unlock its full potential. Originally developed by SGI, the Library continues to evolve under the auspices of the Architecture Review Board (ARB), an industry consortium responsible for guiding the evolution of OpenGL and related technologies. The OpenGL ARB is composed of industry leaders, such as 3Dlabs, Compaq, Evans & Sutherland, Hewlett-Packard, IBM, Intel, Intergraph, Microsoft, NVIDIA, and SGI. The OpenGLA (R) Reference Manual, Third Edition, has been completely revised and updated for OpenGL, Version 1.2, by Dave Shreiner, in collaboration with the ARB.0201657651B04062001
