Lines: 736 Distribution: world Message-ID: <5ktiet$ll$2@murrow.corp.sgi.com> Reply-To: pho@dilow.asd.sgi.com NNTP-Posting-Host: dilow.asd.sgi.com Keywords: OpenGL FAQ ------ Q_1_01: How do I submit changes or additions to this FAQ? A: To request changes or additions, please send e-mail to the FAQ maintainer. See the "Reply-To:" field in the header for the e-mail address. OpenGL licensees may want to contribute information to the question: "What OpenGL implementations are available?" That space is available for any company who wishes to state status reports, release dates, contact names and phone numbers, or other information for their OpenGL implementation. It is asked that this information be relatively brief. Also, for the sake of civility, each implementor is asked not to make comparisons of their implementations against others. Note that although a Silicon Graphics employee maintains this FAQ, Silicon Graphics does not speak for any other company, nor does it uphold the veracity of anyone else's information. ------ Q_1_02: What is OpenGL? A: OpenGL(R) is the software interface for graphics hardware that allows graphics programmers to produce high-quality color images of 3D objects. OpenGL is a rendering only, vendor neutral API providing 2D and 3D graphics functions, including modelling, transformations, color, lighting, smooth shading, as well as advanced features like texture mapping, NURBS, fog, alpha blending and motion blur. OpenGL works in both immediate and retained (display list) graphics modes. OpenGL is window system and operating system independent. OpenGL has been integrated with Windows NT and with the X Window System under UNIX. Also, OpenGL is network transparent. A defined common extension to the X Window System allows an OpenGL client on one vendor's platform to run across a network to another vendor's OpenGL server. ------ Q_1_03: Where are World Wide Web sites with information about OpenGL? A: OpenGL -- The Integration of Windowing and 3D Graphics WWW URL http://hertz.eng.ohio-state.edu/~hts/opengl/article.html Maintained by Harry Shamansky. OpenGL WWW Center WWW URL http://www.sgi.com/Technology/openGL/ Maintained by Thomas McReynolds .

WWW URL http://www.portable.com/opengl/oglndx.htm ------ Q_1_04: What does the .gl or .GL file format have to do with OpenGL? A: .gl files have nothing to do with OpenGL, but are sometimes confused with it. .gl is a file format for images, which has no relationship to IRIS GL or OpenGL. ------ Q_1_05: What documentation is available for OpenGL? A: A 2 volume set, The OpenGL Technical Library (The OpenGL Programming Guide and The OpenGL Reference Manual) is published by Addison-Wesley. The ISBN numbers for both English and Japanese versions are listed below. You can purchase the books in extremely large volume by calling Addison-Wesley (+1-617-944-3700).

Hardware accelerated OpenGL is available through two recently announced products: the mid-range POWERgraphics GXT1000 and the high-end Freedom Series /6000. Both platforms provide h/w support for texture mapping, accumulation, stencil and alpha buffers, as well as a h/w accelerated lighting and geometry transformation pipeline. The Freedom Series is based on an architecture developed by Evans and Sutherland. OpenGL is supported on most other RS/6000 configurations, including the GXT100 and GXT150 graphics adapters for the PowerPC-based /6000's as well as on the CGDA, the Gt1 family, the Gt3 family, and the Gt4 family of graphics adapters. This support is provided through SoftGraphics, a highly-tuned, highly-optimized pure software implementation of OpenGL. (Because of the lack of support for an RGB X11 TrueColor visual on the 3D-HP-CGP and GTO adapters, OpenGL is not offered on these machines. This is the only exception to OpenGL support on the RS/6000 line. Sorry). OpenGL requires AIX 3.2.5 or later. At the Fall '93 Comdex, IBM exhibited a software technology that allowed OpenGL to run under OS/2. The interface that integrates OpenGL with OS/2 was presented to the OpenGL ARB for review. Beta versions of that interface will be available in the first half of 1994, through the OS/2 Developer CD-ROM distribution. To purchase these products, contact your local IBM sales office. - Intergraph Intergraph Computer Systems is currently shipping high-performance, PCI-based, OpenGL accelerators on its TD series of Personal Workstations.
