Changes and additions to bm@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 (chris@dcc.govt.nz)

Here are some 3D accelerator related Web sites:

Introduction

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
machines.
----------------------------------------------------------------------------

Disclaimer

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
false.

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!!!

                              CAVEAT EMPTOR!!!

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
                     http://sunsite.unc.edu/gpc/gpc.html

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
Viewperf:

    What is this Thing Called 'Viewperf'
    -----------------------------------
    Rob Putney, OPC Vice Chairman
    4/21/95

    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
    public.

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 (bm@cs.columbia.edu)

Viewperf can currently be obtained from
            ftp://net1.uspro.fairfax.va.us/pub/gpc/opc/viewperf/

If that directory does not work, try looking on the OpenGL home page at
              http://www.sgi.com/Technology/openGL/opengl.html
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
                           http://www.3Dlabs.com/
or by sending email to info@3Dlabs.com.

The technical specs below were copied directly from the page
                     http://www.3Dlabs.com/300SXinf.html

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.

3D ACCELERATION

   * 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

2D AND GUI ACCELERATION

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

SPECIAL FEATURES

   * 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
     resolution

DISPLAY MODES

   * 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.

FRAMEBUFFER CONTROLLER

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

LOCALBUFFER CONTROLLER

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

INTEGRATED VIDEO TIMING

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.

SHARED FRAMEBUFFER

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
device.

UPGRADE PATH

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
notice.

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:
                         http://www.mmc.com/real3d/

Check there for more information, or call 1-800-393-7730, or send email to
real3d@mmc.com.

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
real-time.

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
effects.

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
package.

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
available.

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
Quickdraw3D.

An Acrobat version of the SPC1500 Datasheet is available via their page at
                  http://www.smos.com/standard/spc1500.htm

For more information contact Giri Venkat, Product Marketing Engineer, S-MOS
Systems (E-Mail: venkat@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.

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
                           http://www.nvidia.com/

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.

COMMENTS:
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
on-screen.

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
                          http://www.rendition.com/

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
DRAM.

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).

CS09) 3Dfx Voodoo

The information in this section was taken from various press releases about
the Voodoo Graphics chipset. I have no contact information for 3Dfx, and no
email to 3dfx.com has yielded a response.

3Dfx Interactive, Inc. has released information on Voodoo Graphics™, a 3D
graphics accelerator specifically designed for 3D entertainment applications
in the coin-operated/arcade and home consumer markets. Designed to enable a
new class of realistic and highly interactive 3D games, Voodoo Graphics
offers expanded capabilities above and beyond the basic 3D functionality
that will be found in commodity Windows and multimedia accelerators. Major
consumer and coin-op OEMs and developers have announced support for the
chipset.

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

CS11) VideoLogic PowerVR

This information was taken from VideoLogic's home page at
                         http://www.videologic.com/

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
hardware.

   * 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
     reality
   * 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
   * Translucency can be applied to whole objects, polygons, or individual
     pixels for effects like dirty glass, fire, water, and even simulated
     lens flare and radiosity
   * True logarithmic colored fog calculated per pixel

The chipsets used in the PowerVR are the NEC ISP (Image Synthesis

CS12) 3DLabs GLINTdelta

The information in this section was taken from a press release provided by
Dave Baldwin (dave_baldwin@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
                         http://www.diamondmm.com/

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
120Hz.

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
2MB (the Diamond Edge 3D 2120XL) or 2MB standard (the Diamond Edge 3D
2200XL.) The VRAM configuration, based on NVIDIA Corp.'s NV1 multimedia
accelerator chip, is available for PCI in 2MB upgradable to 4MB (the Diamond
Edge 3D 3240XL) or 4MB standard (the Diamond Edge 3D 3400XL.) Both chips are
based on NVIDIA's NV1 technology. Diamond estimates pricing for the 2000
series to start at $249 to $299 and for the 3000 series to start at $399 to
$449.
