- Subject: Q1: 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.
-
- ------
- Subject: Q2: 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.

- ------
- Subject: Q4: 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.
-

- IBM
- ---
- IBM offers OpenGL 1.0 at several different price and performance points,
- on most configurations of it's RS/6000 workstation line. 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.

- TGS is providing OpenGL direct to Sun SPARC Solaris 2.x acceleration
- hardware. This differs from other software-only products in that it
- avoids the additional XGL software layer. The result is a fast
- performing and fully functional OpenGL for Sun workstations and
- clone systems. (OpenGL for Solaris from TGS was recently selected by
- Aries Research as the OpenGL to be sold with their SPARC systems.)
-
- * In final beta now, available via ftp
- * 100% functional today
- * Direct acceleration for Sun ZX, Turbo ZX
- * Direct support for GX, TGX, SX board sets
- * X11 network rendering to X terminals, PC-X servers, etc.
- * PostScript hardcopy (on final release)
- * GLX server extension for Solaris (on final)
- * Does not require XGL for rendering
-
- TGS will also be providing OpenGL for Apple Power Macintosh in early 1995,
- with a software-rendering and graphics acceleration version. TGS is
- working with 3D chip/board vendors to deliver accelerated OpenGL for
- the Power Mac platform.
-
- TGS will also be providing OpenGL for Windows 3.1, direct to GDI, to ISV and
- and OEM customers. OpenGL for Windows 3.1 is fully portable with the
- OpenGL for Windows NT 3.5 provided by Microsoft, including the WGL
- component.
-
- * Open Inventor - C++ 3D Graphics Toolkit
-
- TGS will be a single-stop solution for Open Inventor 2.0 on UNIX and
- PC systems, outside of SGI of course!
-
- * Open Inventor for Solaris - shipping (beta)
- * Open Inventor for IBM AIX - shipping (beta)
- * Open Inventor for Windows NT 3.5 - in alpha
- * Open Inventor for Windows 3.1 - 2Q95
- * Open Inventor for Windows 95 - TBA
- * Open Inventor for DEC OSF/1 - 2Q95
- * Open Inventor for HP - 2Q95
- * Open Inventor for Apple - 3Q95
- * Open Inventor for OS/2 - TBA
-
- Note: All of our Open Inventor products are tightly integrated
- into the OpenGL on each system, including support for 3rd
- party acceleration boards from Evans & Sutherland, GLINT,
- and others. TGS is unique in our support for a direct
- to hardware OpenGL for Solaris, Apple and is the only
- vendor to support OpenGL for Win32s (Windows 3.1).
-
- * TGS Power Tools (tm) for Open Inventor
-
- TGS is also developing TGS Power Tools(tm) for Open Inventor which will
- include:
-
- * Power Filters (tm) - Import/Export of 3D metafiles
- * Power Viewers (tm) - 3D Desktop Utilties
- * Web3D (tm) - 3D Internet tools
-
- Additional information on TGS Power Tools will be provided on request.
-
- * Sales and Support
-
- TGS has supported ISV's and professional graphics software developers since
- 1982 from our San Diego headquarters. TGS has regional sales offices in
- San Jose, Houston, Atlanta and Boston. We also have distribution partners
- in Europe and Asia.

- 3Dlabs
- ------
- 3Dlabs is currently shipping the GLINT 300SX, a high performance graphics
- processor providing workstation class 3D graphics acceleration in a single
- chip. Designed to accelerate OpenGL, the GLINT 300SX implements in hardware 3D
- rendering operations such as Gouraud shading, depth buffering, anti-aliasing
- and alpha blending.
-
- Implemented around a scalable memory architecture, the GLINT 300SX reduces the
- cost and complexity of delivering high performance 3D graphics - making it
- ideal for a wide range of graphics products from PC boards to high-end
- workstation accelerators. GLINT based products are already shipping from
- several companies with other developments in progress.
-
- Key features of the GLINT 300SX are:
-
- - Full hardware support for Gourard shading, depth buffering, alpha
- blending, anti-aliasing and dithering;
- - 8, 16 or 32-bits per pixel RGBA and 4 or 8-bit color indexed;
- - Screen resolutions up to 2560x2048;
- - 16, 24 or 32-bit Z buffer;
- - 4 or 8-bit stencil buffer
- - Double buffering, stereo and overlay support ;
- - PCI-bus Rev 2.0 interface with on-chip DMA;
- - 112-bit memory interface.
-
- Since hardware is worthless without software, 3Dlabs have developed a highly
- optimized OpenGL driver for the GLINT 300SX. This OpenGL driver is currently
- available under Windows NT 3.5 and will be ported to other operating systems
- such as Windows 95. With GLINT 300SX and 3Dlabs' OpenGL GLINT driver,
- applications have achieved up to a 3,000 percent 3D display performance
- increase.
