PC 3D Graphics Accelerators FAQ

v 1.2
19 March 1996


Changes and additions to b...@cs.columbia.edu

This document provides a partial -- and not comprehensive -- list of 3D
graphics accelerators for PCs. In particular, I am interested in PCI-based
accelerators. You can help make it more comprehensive by sending me
additional information and/or updates. This information is abstracted and
condensed from the posts of many different contributors. No guarantees are
made regarding its accuracy.

The original motivation for this document came from a list of accelerators
compiled by Chris Hinch, Management Information Systems, Dunedin City
Council, PO Box 5045, Dunedin, New Zealand (ch...@dcc.govt.nz)

The original motivation for compiling this list was to compare the features
of various 3D graphics accelerators becoming available for microcomputers.
In particular, I am interested in PCI-based cards which support OpenGL under
Windows NT, Linux, Solaris x86 (none yet!), etc. and support stereo head
mounted displays. (In fact, of the currently available boards, only one
qualifies. See if you can figure out which one.)

Information which falls in that category will obviously be more complete.
Other information will be included if someone sends it to me, but I won't be
actively researching it myself. As such, there is little or no information
right now about 3D accelerators for high-end machines such as those produced
by SGI, Sun, HP, DEC, etc, except as the ones listed may also work in those


I haven't seen or used many of these cards, and all figures are the
manufacturers own, as near as I can verify. I am not promoting any one card
or company over any other. Any anecdotes, speed comparisons, etc., that I
collect will be included on a purely informational level. USE AT YOUR OWN
RISK. Of course, I will not include anything I do not believe or know to be

No representation is made as to the accuracy of these figures/technical
specs. If you are going to buy/bet the farm/otherwise invest in one of these
products, CONTACT THE MANUFACTURER first and make sure that what you want is
what you'll get!!!


All trademarks etc are copyright of their respective owners etc. etc.

Furthermore, many of these boards are not yet available, so you should find
out delivery dates before getting your heart set on any given one.

Section I: Frequently Asked Questions

[return to index]

Q01) Are there any 3D graphics accelerators for PCs?

I'm glad you asked. There are quite a few, with more coming out all the
time. See the rest of this document for more information.

(Ok, it's a stupid question, but I needed something in the FAQ section)

Q02) How does the performance of these cards compare to graphics
workstations such as those produced by SGI, Sun, DEC, etc?

This question is difficult to answer because there are so many factors
affecting the overall 3D performance on a PC. Most importantly, while many
of the boards listed below have impressive numbers in terms of maximum
number of polygons/second, most only accelerate rendering. What this means
is that you are still bounded by the speed at which your processor can
transform a 3D data stream to a 2D perspective with lighting and material
effects and then ship these numbers over the bus to the graphics card. So,
the processor, processor speed, bus type and speed, software design, etc.,
all effect the final throughput. Thus, a board may perform differently on
two different machines that have the same "specs" (ie. 90Mhz Pentium, PCI
bus) if the bus was designed differently, or if there are other cards on the
bus taking up bandwidth.

What is really needed is a set of comprehensive benchmarks that give some
more realistic numbers about the various combinations of hardware. The NCGA
(National Computer Graphics Association) GPC (Graphics Performance
Committee) (comprised of the major vendors along with UNC and SDSC) is an
organization primarily concerned with developing benchmark standards and
performance characterizations for graphics hardware.

Check out

for information about the GPC activities.

Unfortunately, the GPC Quarterly is about US$200/year, which is beyond my
budget. Thus, to get their benchmark results, you'll have to talk to them.
However, the benchmarking tool they use to measure OpenGL performance,
called Viewperf, is available for free. From the README that comes with

What is this Thing Called 'Viewperf'
Rob Putney, OPC Vice Chairman

Viewperf is a portable OpenGL performance benchmark program
written in C. It was developed by IBM. Viewperf provides a vast amount of
flexibility in benchmarking OpenGL performance. At the current time,
the program runs on most implementations of UNIX, Windows NT, and OS/2.
The OpenGL Performance Characterization (OPC) Committee has endorsed
Viewperf as its first OpenGL benchmark and results
were first published using it in 4Q94 version of The GPC Quarterly.

OPC member companies have ported the Viewperf code to their operating
system and window environments. The OPC Committee maintains a single
source code version of the Viewperf code that is available to the

In future versions of this FAQ, performance measurements will be added in
another section at the end. Stay tuned. If you have any measurements using
Viewperf, please send them to me (b...@cs.columbia.edu)

Viewperf can currently be obtained from

If that directory does not work, try looking on the OpenGL home page at
which should contain a pointer to ViewPerf.

Q03) What are all the features, anyway?

Many of the features discussed in the 3D graphics card brochures may not be
meaningful to people not already familiar with 3D graphics. Z-buffering,
quadratic texture mapping, gouraud shading, fog, etc., are new to many
people. However, in the interest of time and space, I am not going to
discuss them here. For a comprehensive introduction, refer to a 3D graphics
textbook, such as "Computer Graphics: Principles and Practice" by Foley, van
Dam, Feiner and Hughes.

Section II: 3D Chipsets available now or in the near future.

There are numerous 3D chipsets being worked on, but these 2 happen to be the
ones I have detailed information both on the chips and on boards built using
them. If I get more information on other chips, I will include them here.

CS01) 3DLabs GLINT 300SX

First, a comment about the GLINT 300SX chip, which I will make because it
was not clear to me when I first read their specs. They mention texture
mapping acceleration, but on the 300SX texture maps are held in host memory
and per pixel information is sent to the chip which performs the necessary
interpolations and applications. For the upcoming 300TX, the texture maps
are held in local memory on the graphics card (the "localbuffer") and the
host just sends per vertex information to the chip which performs all the
texture mapping calculations.

Information on the 300SX can be obtained from the 3DLabs home page at
or by sending email to in...@3Dlabs.com.

The technical specs below were copied directly from the page

GLINT 300SX Overview

The GLINT 300SX high performance graphics processor combines workstation
class 3D graphics acceleration and state-of-the-art 2D performance in a
single chip.

GLINT is capable of processing 300,000 shaded, depth buffered and
anti-aliased polygons/second. The chip provides complete 32-bit color, 2D
and 3D acceleration, an on-chip PCI-compliant local bus interface and
integrated LUT-DAC control, making a complete graphics subsystem possible
with minimal chip count.

All the rendering operations of OpenGL are accelerated by the GLINT 300SX,
including Gouraud shading, depth buffering, anti-aliasing, alpha blending,
and texture mapping.


* 100% OpenGL compliant rendering operations in hardware
* Point, line, rectangle and polygon primitives
* Gouraud shading, depth buffering, anti-aliasing, dithering, depth
cueing, texture map filtering and alpha blending
* 2.5 Giga operations per second
* 300K Gouraud shaded, depth buffered triangles/sec


* True color acceleration of window systems such as Win32 and X11
* Accelerated bitBLT, line drawing, fills, text and window clipping


* 64-bit hyper-pipelined architecture
* Vertex level interface
* 112-bit pixel datapath to memory
* High quality 16 and 8-bpp dithering of 24-bit graphics images
* Fast frame and depth buffer clears
* Shared framebuffer interface for easy multimedia integration
* VRAM block fill and bit masking
* Anti-aliasing for high quality images at 4x4 and 8x8 sub-pixel


* Resolutions up to 2560x2048
* 8, 16 or 32-bits per pixel RGBA and 4 or 8-bit color indexed
* Packed 8, 16 and 32-bit pixels
* Supports advanced modes: double buffering, stereo and overlays

GLINT 300SX Graphics Architecture

The GLINT 300SX delivers 3D and GUI rendering functionality to improve the
performance and quality of graphics applications and APIs.

* Gouraud shading
* Depth buffering
* Anti-aliasing
* Dithering
* Depth cueing and fog
* Texture mapping
* Scissor and stipple masking
* Alpha blending
* Logical Operations (e.g. XOR)

The unique hyper-pipelined architecture and 112-bit memory datapath ensure
that multiple rendering operations can be combined with no performance
penalty - allowing a Gouraud shaded polygon to be processed just as fast
when depth buffering, dithering and anti-aliasing are enabled.


The 64/32-bit framebuffer controller directly interfaces to VRAM or DRAM
framebuffers and supports a wide range of pixel depths, resolutions and
memory sizes - enabling systems to be tuned to meet specific
price/performance targets.

* 1-32 MBytes VRAM or DRAM
* 8,16 or 32-bit RGBA color
* 4 or 8-bit color indexed
* 2, 4, 8 pixels per 64-bit word
* 640x480 to 2560x2048
* VRAM arbitrary shape block fill
* VRAM bit masking
* Framebuffer bypass mode


The localbuffer holds optional off-screen information for each pixel
including; depth (Z) values, stencil data, arbitrary window clip planes,
plus a control field for fast window clearing. The format for each field is
user defined, up to a maximum of 48 bits.

* 0-48 MBytes DRAM
* 0-48-bits wide
Depth: 0, 16, 24, 32-bit
Stencil: 0, 4, 8-bit
Window clipping: 0, 4-bit
Fast depth clear: 4, 8-bit
* Localbuffer bypass mode


An internal timing generator and VRAM transfer controller are incorporated
into the GLINT 300SX processor. Advanced systems requiring overlays, stereo,
interlace or very large framebuffers can be supported using an external
timing generator.


The GLINT 300SX's on-chip shared framebuffer interface is a fully integrated
implementation of S3's interface, allowing GLINT to use video and multimedia
co-processors, or for the GLINT to be used as a 3D coprocessor to an S3


The GLINT 300SX is the first of a family of GLINT graphics processors that
are designed to meet the demands of the graphics designer. The GLINT300TX,
is a second generation pin compatible processor that enhances the SX's
texture capabilities - supporting local texture storage and pixel address
generation for all OpenGL texturing modes.

NOTICE: 3Dlabs reserves the right to change the above specifications without

From looking at the various boards, it appears that typical performance
quotes are in the following range:

* 3D Gouraud shaded, depth buffered, window clipped, stippled, dithered,
and alpha tested rendering performance with 24-bit RGB color depth is
the following:
o 300K 25 pixel triangles/sec
o 500K 10 pixel vectors/sec
o 8M independent points/second
o 500K 9x13 pixels characters/second
* 2D Graphics performance
o 1M 10 pixel vectors/sec
o 500K 10x10 pixel, flat shaded rectangles/sec
o 500K 9x13 pixels characters/second
o Scroll Rate 48M pixels/second - 8 bits/pixel

CS02) Lockheed Martin Real3D

Information on the Lockheed Martin Read3D chipset was obtained from their
WWW server at the following URL:

Check there for more information, or call 1-800-393-7730, or send email to

The following is taken from a press release found at that site:

The REAL3D(tm) chipset is based on real-time computer image generation
technology that gives a combination of dynamic response and realism
previously available only on dedicated graphics workstations and high end
custom image generators.

The first product will be the R3D/100 graphics accelerator. Key performance
attributes of the new chip set include an embedded 100 MFLOPS geometry
processor, pixel write rates of up to 33 million pixels per second, up to
750,000 polygons per second, line processing up to 1.5 million per second,
and provides up to 192 color texture maps (128 x 128 mipmapped) in

The new product is an outgrowth of Lockheed Martin's proprietary computer
graphics technology previously used in high performance military simulation,
engineering research and training applications first developed for astronaut
training and military flight simulators.

The chip set provides faster processing through its patented hardware design
which incorporates geometry processing, rasterization and texture mapping.
The R3D/100 embedded floating point geometry processor removes significant
processing burden from the host CPU. The patented texture processor applies
color mipmapped texture to polygons in true 3D corrected perspective.

Designed as a true polygon processor with texture processing and scaleable
texture memory from the outset, the R3D/100 chip set includes dedicated
hardware acceleration of mipmapped texturing that provides continuous high
fidelity image quality. This chip set simulates spotlights, fog and
realistic curved surfaces. Additionally, improved image quality is provided
with multi-pass anti-aliasing.

The R3D/100 chip set directly interfaces with Microsoft 3D/DDI and supports
all 3D/DDI-compliant APIs, such as OpenGL(tm) and comes with device driver
software and a device driver kit.

CS03) S-MOS SPC1500 3D Graphics Geometry Processor

S-MOS Systems is offering the industry's first commercially available single
chip 3D geometry accelerator for the PC marketplace.

The SPC1500 will work together with any 3D rendering processors to
accelerate 3D graphics up to 300K+ lighted triangles per second.

Why is geometry processing acceleration important?
Rendering processors alone, even on Pentium class machines, can not deliver
true workstation class performance. This is because even the fastest CPUs
today are quickly overcome by the amount of algorithmic processing necessary
to transform a 3D data stream to a 2D perspective with lighting and material

The SPC1500 integrates a 150Mflop dual floating point engine, an on-chip DMA
processor, on-chip ROM to store the algorithm instruction set, and an
on-chip RAM cache to store customer instructions in a single 223 pin PGA

Easy integration
S-MOS Systems provides a complete design package for the system integrator
and board vendor.....

PCI Reference Designs
S-MOS Systems provides reference designs and evaluation kits showing the
capabilities of the SPC1500 running OpenGL on the WindowsNT platform. Full
technical manuals, electronic gerber files, and applications notes are

WindowsNT and OS/2 Support
S-MOS Systems provides OpenGL compliant software and system utilities for
the WindowsNT platform. This software supports any rendering board (2D or
3D) that supports 3D DDI. It will also supports direct data transfer to the
leading 3D rendering board vendors.

MacOS Support
S-MOS Systems will will support software drivers and system utilities for

An Acrobat version of the SPC1500 Datasheet is available via their page at

Systems (E-Mail: ven...@smos.com).

CS04) ARTIST Graphics 3GA Graphics Processor

The 3GA is a 2D and 3D graphics coprocessor with a fast VGA core which means
that boards designed around the 3GA will not only run the next generation of
software, but will run the software programs of today faster than ever
before. Bus support for PCI, ISA, and MicroChannel means that the 3GA is one
of the most flexible graphics chips available, as well as the most powerful.

The 3GA's features include built-in Windows acceleration, 2D and 3D lines,
flat-shading, Gouraud-shading, and texture-mapping. Initial benchmarks show
that the 3GA is significantly faster than the S3 968 Windows accelerator.

Technical information about the chip design is also available, and if you

CS05) NVidia/SGS-THOMSON NV1/STG-2000 Multimedia Accelerators

The information I currently have is from the press releases on the NVIDIA
Home page at

NVIDIA Corporation and SGS-THOMSON, today announced the introduction of the
NV1 and STG2000 Multimedia Accelerators. The first complete multimedia
accelerators, the NV1 and STG2000 represent the culmination of a strategic
partnership that began over a year ago. The technology will deliver powerful
multimedia capabilities exceeding that of next generation game consoles,
while preserving the versatility of the personal computer. Available now,
they are single-chip Multimedia Accelerators that delivers the power of
real-time photorealistic 3D graphics, full-motion video and special effects,
and concurrent high-fidelity audio for interactive multimedia.

They feature stunning 3D graphics capabilities with texture-mapping,
lighting effects, and a special feature called video texturing. This unique
feature allows developers to texture a 3D object with full- motion video,
creating new levels of realism never before possible in a PC application. In
addition, they deliver concurrent high-fidelity wave-table audio,
full-motion video acceleration, world-class GUI acceleration, enhanced
digital game port, and an internal synchronization timer for multimedia.

Market coverage will be provided by two versions of the multimedia
accelerator. NVIDIA will market and sell the NV1 (VRAM version) while
SGS-THOMSON will market and sell the STG2000 (DRAM version). Both products
are available with PCI and VL bus interfaces. The NV1 or STG2000 allow
leading-edge adapter card and PC OEMs to offer a multimedia sub-system with
dazzling 3D, wave-table audio, GUI acceleration, enhanced game port
performance, and video acceleration -- on a single-card with a street price
of around $200.

There are no current plans to do an NT driver, or OpenGL, although some
third parties have expressed interest. They don't think consumers will be
running applications on OpenGL or NT. The chips does not support texture
memory. They do forward texture mapping: specify the control points (4 for
bilinear, 9 for quadratic surface), specify the subdivision of the texture,
then write texels. As you write each texel the chip computes its location
on-screen, optionally computes a blend value for it, and it shows up

I'm not sure, but it doesn't not appear to have a Z-buffer, either.

CS06) Rendition Vérité

The information I currently have is from the Rendition home page at

Rendition's first product, the Vérité(tm), is a single chip 3D graphics
engine, GUI accelerator, digital video accelerator and VGA engine for the
personal computer market designed for add-in graphics cards and OEM
motherboard implementation.

Advanced Rendering Features
The Vérité(tm) supports texture mapping with correct perspective, bilinear
filtering, z-buffering, alpha blending, fog, and other advanced rendering
features. These features will enable game developers to deliver the most
engaging, realistic interactive entertainment to date.

Sustainable High Performance
Design decisions were made with input of many game developers to ensure a
real performance advantage.

Embedded RISC Core
The Vérité(tm) employs a unique architecture, which combines a fully
programmable RISC core with a hard-wired pixel pipeline.

Optimized Memory Controller
In the cost-sensitive markets which Rendition will compete, it is imperative
to focus on total solution cost for the OEM customer. It uses low cost EDO

Support for Two Dimensional GUI and Multimedia Acceleration
The Vérité(tm) also provides conventional Windows acceleration, and
incorporates all control logic required for a standard graphics card. For
acceleration of digital video playback, e.g. MPEG and Indeo, the Vérité(tm)
provides YUV-to-RGB color space conversion and image scaling with bilinear
interpolation for smooth full-screen full-motion video playback.

VGA Compatibility
All of this advanced functionality will be of little value if users cannot
run their older applications. For this reason, Rendition has incorporated a
VGA-compatible core into the Vérité(tm).

that will be found in commodity Windows and multimedia accelerators. Major
consumer and coin-op OEMs and developers have announced support for the

3Dfx Interactive has announced that Orchid Technology and FMI Graphics
Products, a business unit of Fujitsu Microelectronics, Inc. have signed OEM
agreements to develop consumer 3D game boards based on Voodoo Graphics.

In addition to elementary 3D functionality, including perspective correct
polygons with point sampled texture mapping, Z- and double-buffering,
Gouraud shading capabilities and standard VGA resolution, 3Dfx Interactive
has also included level-of-detail (LOD) MIP mapping, bi-linear and advanced
filtering and SVGA resolution support. In addition, the chipset delivers
realistic imagery through sub-pixel correction, alpha blending, and
anti-aliasing. Most importantly however, unlike other multimedia
accelerators that suffer significant performance degradation when available
3D features are used, Voodoo Graphics was designed to simultaneously offer
all of these features at real-time frame rates.

Voodoo Graphics also support per-pixel effects such as fog, translucency,
and transparency, texture compositing, a variety of lighting techniques,
texture morphing, animated textures, and reflection mapping.

The Voodoo Graphics chipset supports full screen games under popular PC
operating systems including Microsoft Windows 95, MS DOS, and Microsoft
Windows 3.1 using 3D APIs including Microsoft's Direct3D, DirectDraw,
3D-DDI, and Reality Lab 2.0, as well as Intel's 3DR. The chipset also
supports embedded operating systems for coin-op/arcade platforms.
Development environments supported by the chipset include MS DOS, WindowsNT,
Windows95, and Silicon Graphics' IRIX. Important development tools and APIs
supported by Voodoo Graphics include Silicon Graphics' IRIS GL and OpenGL,
AutoDesk's 3D Studio, MultiGen's GameGen, and Gemini Technology's OpenGVS.

Packaged in a two-chip set, the Voodoo Graphics architecture is a PCI Bus
2.1 compliant device that operates transparently with existing VGA and
Windows accelerators via analog pass through or shared frame buffer
implementations on Intel or RISC-based PCI platforms. The Voodoo Graphics
chipset is priced at less than $75 in 20,000 piece quantities. On
perspective correct, texture mapped, Z-buffered, filtered, LOD MIP mapped,
fogged, alpha blended, 50-pixel triangles Voodoo Graphics delivers more than
45 megapixels per second fill rate and over 350,000 triangles per second
polygon rates on a Pentium 90. The first chip, pixelfx, is the primary
graphics controller and contains interfaces to the PCI bus and companion
texture processing unit, texelfx. The 3Dfx Interactive pixelfx graphics
controller is packaged in a 240-pin PQFP. texelfx, the advanced texture
processing unit, is packaged in a 208-pin PQFP.

CS11) VideoLogic PowerVR

This information was taken from VideoLogic's home page at

PowerVR was developed jointly by VideoLogic and NEC. The system is fully
scalable, allowing multiple chips to be ganged together giving a linear
increase in speed as chips are added. It can be used in a wide range of 3D
applications and entertainment markets from games consoles, through PCs,
right up to high-end arcade machines. This also allows content producers to
target a range of different platforms without redesigning their titles.

PowerVR’s core 3D rendering algorithm is infinite plane (surface) based.
This approach allows the system to efficiently cater for polygons, polygon
meshes, infinite planes, and convex objects. Its polygon object rendering
allows the use of conventional, industry-standard APIs such as Microsoft’s®
Direct3D™, and the ability to directly process infinite planes and convex
objects allows PowerVR to provide advanced features such as full shadows and
searchlights in real-time. In addition to support for industry-standard
APIs, PowerVR has its own high-level object oriented API, called PowerVR
SGL, that provides full access to all the capabilities of the PowerVR

* Real shadows can be cast from any object over any surface, and updated
every frame
* PowerVR’s equivalent 32-bit Z buffer makes solid outdoor objects a
* Pixel perfect hidden surface removal
* Anti-aliased textures using PowerVR’s mip mapping stops shimmering
* Perspective-correct textures do not bend because PowerVR performs a
division per pixel
* Smooth shading does not change when rotated

CS12) 3DLabs GLINTdelta

The information in this section was taken from a press release provided by
Dave Baldwin (dave_b...@3dlabs.com.)

The GLINT Delta is 3DLabs 3D Geometry Pipeline Processor. It accelerates
GLINT or PERMEDIA-based Graphics Boards up to three times by off-loading up
to 70% of the 3D geometry processing load into a hard-wired 100MFlop
processor that delivers 1 Million polygons/second for under $50.

3DLabs claims that when used on a high-performance PC, using a Pentium Pro
processor, GLINT Delta-based designs have been measured to deliver over 750K
polygons per second via OpenGL. For intensive 3D graphics applications,
GLINT Delta significantly improves overall system performance by freeing the
CPU from demanding 3D pipeline calculations -- providing more processor time
for application level processing.

The Delta is implemented as a PCI bridge with full PCI master capability. It
acts as a front-end processor to GLINT or PERMEDIA and processes the setup
calculations for 3D primitives such as lines and polygons. GLINT Delta's
advanced design includes support for texture-mapping, anti-aliasing and 16,
24 or 32 bit Z buffering - all with high-precision, sub-pixel accuracy.
GLINT Delta's processing throughput is up to 1 million texture-mapped,
Z-buffered polygons per second. GLINT Delta supports full byte-swapping and
is compatible with PC or Macintosh systems.

GLINT Delta provides a glueless, single-chip geometry solution for GLINT
300SX or PERMEDIA. GLINT Delta also supports multiple GLINT rendering
processors -- also without glue logic -- for high-end desktop, arcade and VR
applications seeking unmatched rendering performance. The combination of
GLINT Delta and two GLINT rendering processors enables board vendors to
provide dual- GLINT 3D acceleration on a single PCI board, seamlessly
combined with full Windows performance and functionality.

PERMEDIA does not require GLINT Delta to provide class-leading performance,
however the ability to combine the two devices in a low-cost designs enables
board vendors to provide a wide-range of price/performance options at
performance levels far beyond other 3D chip offerings.

GLINT Delta is software compatible with the GLINT and PERMEDIA families, and
3Dlabs' extensive range of software drivers is already available for GLINT
Delta-based boards. These drivers include: Windows NT, Windows 95, OpenGL on
Windows NT, OpenGL on Windows 95, Heidi from Autodesk, Direct3D from
Microsoft, CGL from Creative and QuickDraw 3D and QuickDraw 3D RAVE from
Apple. The drivers for Windows NT and OpenGL are available on Intel, Alpha,
MIPS and PowerPC processors.

NVIDIA01) Diamond Edge 3D Accelerators

The information on these boards were obtained from Diamond Multimedia
Systems home page at

They contain the NVidia/SGS-THOMSON NV1/STG-2000 chipset.

The boards are PCI-based and sport a digital gameport for precise joystick
control, as well as two video gameports that allow specialized, multi-player
versions of Sega Saturn titles, such as the arcade hit Virtua Fighter Remix,
to be played on Windows 95 PCs. It is expected to be initially shipped in
late October at consumer prices starting from $249 - $299.

With Diamond Edge 3D accelerators, game developers can support resolutions
as high as 1024x768 with 65,000 colors while still achieving fast, realistic
action. In the past, this type of technology was available only to engineers
and designers with prices topping $2,000.

The 3D functions of the Diamond Edge 3D were designed specifically for the
consumer multimedia market where the primary application is interactive
entertainment. Traditionally, 3D graphics were created by drawing large
numbers of successive polygons using the CPU, which resulted in a tradeoff
between detailed graphics and speed of interactivity. With the Diamond Edge
3D, the hardware engine accelerates polygon rendering of real-time,
texture-mapped 3D images at the highest possible frame rates without unduly
slowing the CPU. In addition, the Diamond Edge 3D can create realistic 3D
graphics by using nine control points to create a curved surface, called
quadratic texture mapping (QTM).

Features of the Diamond Edge 3D engine include fast polygon rendering,
texture-mapping for photo-realism, quadratic texture-mapping for perspective
correction and rendering of curved surfaces, as well as special effects
including diffused lighting, specular highlights, reflection mapping and
alpha blending for fog, smoke and transparency.

High Performance 2D Acceleration

The Diamond Edge 3D delivers fast 2D Windows acceleration at resolutions as
high as 1280x1024, color depths to 1 billion and refresh rates of up to

The DRAM version of the Diamond Edge 3D, based on SGS Thomson's STG2000
multimedia accelerator chip, is available for PCI-bus in 1MB upgradable to

B03) Evans & Sutherland Freedom



SALT LAKE CITY, March 2, 1995 Evans & Sutherland Computer
Corporation (NASDAQ: ESCC) today announced Freedom Graphics(tm)
for the Personal Computer. Freedom Graphics is the first product
to bring the 3D graphics technology of E&S to the personal
computing environment.

Freedom Graphics is an implementation of the specialized features
that 3D graphics applications require for smooth, fast execution.
Users can produce impressive realistic images with the product's
rich feature set and high-performance graphics for Windows/NT(r)

The graphics card supports the OpenGL(r) software application
programming interface and is designed to accelerate OpenGL in the
PC environment. Freedom Graphics is a PCI bus-based card that
incorporates the same technology as the Freedom Series graphics
accelerators which supply high-end graphics for the world's
largest workstation vendors. Ideal markets to take advantage of
the extensive feature set of Freedom Graphics are CAD, Industrial
Design, Simulation, Visualization, Animation, Entertainment and
Game Development. Supported PC processors include MIPS(tm),
Pentium(r) and Power PC(tm).

"The interest being generated by Freedom Graphics is
extraordinary," said Jim Oyler, President and CEO of Evans &
Sutherland. "Freedom Graphics allows a low-cost PC-based system to
achieve the performance of a much more expensive workstation. This
is going to be an explosive market in the very near future."

Evans & Sutherland is the only 3D graphics vendor with a product
line that spans the entire computing industry from the personal
computer up to multi-million dollar flight simulators and
location-based entertainment systems.

"We are pleased that Evans & Sutherland has applied their
knowledge and experience in high-performance real-time 3D graphics
to the PC marketplace," said Tom Coull, President of Sense8
Corporation. "WorldToolKit and Freedom Graphics will offer a
definitive hardware-accelerated solution for texture-mapped
virtual reality applications."

Freedom Graphics' feature set includes real-time 3D graphics
rendering and animation, hardware based 24-bit texture
acceleration, scalable texture memory up to 16 MBytes, bi-linear
and tri-linear MIP-mapping, specular highlights, fast set-up
calculations, full scene antialiasing, transparency and depth
cueing. The additional experience of E&S with OpenGL will also
result in significant performance advantages for applications
using the OpenGL library from E&S.

According to Ian Reid, Vice-President of Marketing at Advanced
Visual Systems, "Freedom Graphics offers a new level of capability
for the PC user and AVS/Express allows any PC developer to take
immediate advantage of features such as hardware texture-mapping
and transparency. It's the ideal combination."

Freedom Graphics performance under Windows/NT and OpenGL is
300,000 triangles/second. The card will list price at US$2450 with
second quarter availability through OEMs and VARs. Freedom
Graphics was first shown at Fall Comdex '94 in Las Vegas.

The significance of Freedom Graphics lies in its delivery of a
graphics feature set at unsurpassed performance levels. Advanced
features such as texture mapping are still unavailable from any
other vendor for under US$10,000. Freedom Graphics also provides
performance not yet seen in the 3D PC graphics market. Nearest
competitors for performance provide minimal feature sets and are
only available at much higher prices.

Evans & Sutherland is a leader in advanced 3D graphics and
visualization systems for science, industry, education, and
entertainment. The Graphics Systems Division provides graphics
hardware and software solutions that are sold and supported by

COMMENT: From Chris Hinch (ch...@dcc.govt.nz):

I heard comments on comp.sys.opengl that, at the moment, the
Impression Plus doesn't have "true" OpenGL support under Windows
NT. I don't know if this is correct or not.

From Blair MacIntyre:

This is partially true. Someone from Microsoft posted saying that
NT 3.51 will include the appropriate driver for OpenGL for this

B05) Oki TrianGL

More information on Oki and their products can be found on their web page
(www.oki.com) or by sending email to tri...@oki.com

The information here was extracted from the page

Oki's TrianGL is aimed at 3D applications using the OpenGL graphics API.

At the heart of the TrianGL is a custom, high-performance rendering ASIC--a
drawing engine which provides both 2D and 3D acceleration. The chip
interfaces directly to multiple banks of video RAM via a 80-bit data bus,
boosting overall drawing performance.

The four banks of VRAM, 10 MBytes in all, each operate independently to
maximize the performance efficiency of the rendering ASIC. For many drawing
primitives, all the banks can operate in parallel. However, for certain
primitives, such as vector drawing or triangle drawing, address and color
values are sent from the ASIC to the appropriate memory banks in a
pipelined, serial fashion. TrianGL's use of triangle drawing primitives
gives the board a major performance advantage over other products which use
simpler span primitives.

Two separate RGB buffers allow true hardware double buffering for smooth,
artifact-free animation. An independent 24-bit Z buffer is dedicated for
hidden surface removal during 3D object rendering. And finally, eight
utility planes support board-specific video options such as overlays, window
types and RGB double buffering. In order to support VGA compatibility, a
VESA standard VGA passthrough interface is included on the board.

Accelerated Drawing Operations

* Solid Rectangle Fill - 266 M pixels/second
* Pattern Rectangle Fill - 66 M pixels/second (8-bit), 33 M pixels/second
* Screen to Screen Copy - 33 M pixels/second (8-bit), 16 M pixels/second
* Raster Operations - 33 M pixels/second
* Line (2D) - 33 M pixels/second, 1.4 M 10-pixel lines/ second, random
* Triangles (3D Gouraud shaded) - 22 M pixels/second, 250K 50-pixel
triangles/second, random orientation

TrianGL Features

* Enables Workstation-class 3D performance on PCs
* Accelerates OpenGL API compatible graphics under Windows NT for 2-D and
3D applications
* Allows fully configured 3D systems for under US$10,000 (TrianGL pricing
has not been set, but it should be around US$2500)
* True 24-bit graphics
* Fully double-buffered 24-bit VRAM buffers
* 24-bit hardware Z-buffer
* 8 bits of hardware utility planes
* Large 8 kbyte FIFO allows independent host operation
* Fast internal RAM for storing patterns,line styles, and intermediate
* 64 x 64 hardware cursor
* Host to Screen Copy
* Screen to Host Copy
* Color Expansion
* Color Interpolation
* Linear Frame Buffer Support


* Dimensions - Full-length VLbus/ISA board 13.5" length x 5" height
* Power Dissipation - 15 Watts typical (20 Watts maximum)
* Bus Interface - VESA VLbus Local Bus Standard, Rev. 1.1 Local Bus
Target, 32-bit data path
* VGA Support - VESA Standard VGA passthrough
* Monitor Support - Software-programmable 1024 x 768, non-interlaced,
vertical refresh rates from 60 to 76 Hz
* Frame Buffers - Two 24-bit, 1024 x 768 RGB
* ZBuffer - 24-bit, 1024 x 768
* Memory - 10 Mbytes VRAM, 512 bytes internal RAM
* FIFO - 8k x 32-bit for graphics commands and data

Software Support

Oki supports TrianGL on PC and RISC PC platforms with host software drivers
for Windows NT 3.5. OpenGL and DDI support are available for Intel and Mips
platforms. Other popular APIs, including AutoCAD, will be supported in
future software releases.

B06) Intergraph GLZ Series

The GLZ series accelerates OpenGL[tm] graphics on Intergraph Computer
Systems' TDZ workstations. GLZs let you manipulate Gouraud-shaded 3D models
by adding realistic effects such as lighting, translucency, and textured
surfaces; and performing spectacular flythroughs, walkthroughs, and
animations -- all in real time, at high resolutions, and in true color.

By performing shading and geometry operations in dedicated hardware, GLZs
ease the load on the TDZ's Pentium[tm] processor(s) and cut down traffic on
the PCI bus, which results in dramatic improvements in graphics performance.

The GLZ family supports Intergraph's 17- and 21-inch multi-sync monitors and
21- and 27-inch InterVue monitors at resolutions up to 1,600 x 1,280 pixels.
The GLZs support dual screens and are ready for stereoscopic display on any
stereo-ready monitor. (LCD shutter glasses and emitter modules are required
and are available from Intergraph Computer Systems.)

The GLZ family offers a selection of 34, 24, or 12 megabytes of VRAM. 24
megabytes of VRAM supports resolutions up to 1,600 x 1,280 with 16.8 million
colors (true color). 12 megabytes of VRAM suppots true color at a maximum
resolution of 1,152 x 854. 34 megabytes of VRAM supports a 32-bit Z buffer,
double-buffered true color, and display capabilities such as translucency
and overlay at resolutions up to 1,600 x 1,280.

Intergraph Computer Systems offers six different GLZ configurations.


The top of our 3D graphics accelerator line -- offers shading acceleration,
geometry acceleration, and texture-processing for fast, real-time rendering
of complex and detailed designs.

digital-to-analog converters, enabling user control of gamma values
with no loss of color resolution


Our GLZ5 offers the same high-performance shading and geometry acceleration
as does GLZ6. With 12 MB of VRAM, GLZ5 supports resolutions up to 1,152 x
864. Two megatexels (8 megabytes of texture memory) provide more than enough
texture storage for adding patterns to furniture, waves to water, or trees
to parks and forests.

GLZ5's low price may even tempt you to invest in dual screens and LCD
shutter glasses for a stereoscopic adventure into virtual reality!

Product highlights (same as the GLZ6, except where noted)

* 12 MB of high-speed VRAM for 92 bit planes of video memory at
resolutions up to 1,152 x 864, providing:

480 pixels to 1,152 x 864

GLZ4 and GLZ3

GLZ4 and GLZ3 support both shading and geometry acceleration. If you need
fast, accurate rendering of complex solid models but don't normally require
realtime texture processing for photorealism, GLZ4 (24 MB of VRAM) or GLZ3
(12 MB of VRAM) will give you performance that more than meets your
expectations. Don't worry if you occasionally need to render a textured
image. Thanks to OpenGL, texture processing is fully supported in software.

B15) S3 ViRGE and ViRGE/VX

The information in this section was taken from the S3 homepage at:

The ViRGE 64-bit DRAM-based accelerator combines a 135MHz RAMDAC and clock
synthesizer with the multimedia capabilities of S3's Trio64V+ including
video acceleration, video playback using both software and hardware sources,
live video support and the ability to connect with popular NTSC and PAL
decoders. Additionally, ViRGE is SVGA-compatible, so as to support legacy
DOS applications and games, and provides high-performance 2D GUI
acceleration support for resolutions up to 1280 x 1024 x 256 colors at 75Hz.
S3's ViRGE accelerator also provides support for all major 3D APIs,
including OpenGL, Microsoft's Direct3D and RealityLab, as well as Argonaut
BRender and Criterion Renderware.

The ViRGE/VX product offers all of the same features as the DRAM-based
ViRGE, but substitutes support for VRAM and WindowsRAM (WRAM), and increases
the integrated RAMDAC performance level to 220 MHz. Resolutions up to
1600x1200x16 million colors @ 75Hz are supported and higher memory bandwidth
is enabled by the block write feature.

64-bit S3d Engine

The S3d Engine provides 2D acceleration for excellent Windows applications
performance and a full-featured high-performance 3D rendering engine for
games and other interactive 3D applications.

The S3d Engine incorporates the key Windows accelerator functions of BitBLT,
line draw and polygon fill. 3D features include flat shading, Gouraud
shading and texture mapping support. Advanced texture mapping features
include perspective correction, bi-linear and tri-linear filtering, MIP-
Mapping, and Z-buffering. The S3d Engine also includes direct support for
utilizing video as a texture map. These features provide the most realistic
user experience for interactive 3D applications.

Other advanced features of the S3d Engine include S3 proprietary compressed
texture formats for improved performance and reduced memory requirements, as
well as support for S3's MUX buffering (pat. pend.) feature, which allows
for Z-buffering support with no additional memory requirement.

Streams Processor

The S3 Streams Processor provides the stretching and YUV color space
conversion features required for full screen video playback with both
software CODECs and hardware MPEG-1 sources.

The Streams Processor allows simultaneous display of graphics and video of
different color depths. For example, it is possible to display 24 bpp-
equivalent video on top of an 8- bit graphics background. This saves memory
bandwidth and storage capacity while permitting higher frame rates.
