E&S Ships One Of The First 3D Solutions For Linux 

E&S Lightning 1200LX Board Availability and Software Support Leads Competition

SALT LAKE CITY, UTAH, January 31, 2000 — Evans & Sutherland
(E&Sâ) (NASDAQ: ESCC) today announced that the company is now
shipping the E&S Lightning 1200LXä, one of the first fully
hardware-accelerated 3D solutions for the desktop Linux market.  E&S
Lightning 1200LX delivers to Linux users OpenGL, high-level
workstation graphics features, that were previously only available
only on UNIX and NT-based systems., to Linux users In addition, E&S
Lightning 1200LX supports the first available graphics programa number
ofvarious design &and visualization applications for Linux, including
Side Effects Software’s Houdini 4.0 and Engineering Animation,
Inc.’s WorldToolKit 9.0., giving digital content creators,
designers, and animators  our customers an additional choice in
operating systems.  The addition of Linux capability demonstrates the
company’s commitment to continually providing upgrades and
improvements to its existing graphics cards, offering customers
enhanced capability and performance without requiring them to purchase
new hardware. 
  Based on company’s E&S’s innovative REALimageâ technology,
the E&S Lighting 1200LX offers professional workstation graphics
features, including 24-bit Z-buffering, MIP-mapped texturing,
antialiased lines, transparency, fog, and overlay planes.  It also
provides resolutions up to 1280x1024 at true color, with performance
rates up to 4.0 million triangles per second and a sustained fill
rate of 90 Mpixels/second.  E&S originally developed REALimage
technology to bridge the gap between traditional UNIX workstations
and PCs.  Today, REALimage takes this a step further to Linux. 

“While many leading companies are announcing plans to support the
popular Linux operating system, E&S is the first and only company
delivering Linux technology for the professional workstation graphics
customer,” said Pratish Shah, vice president of marketing for the
E&S Workstation Graphics Division.   “Development of the Linux
driver for our graphics accelerators is consistent with our commitment
to continuing to enhance and add options to our boards, allowing our
customers to upgrade their capabilities without investing in new
hardware.  Our cards keep getting better and better.” 


XiI Graphics
“We are pleased to be working with E&S to bring workstation-class,
professional 3D graphics on Linux and Intel hardware to the
market,” Thomas Roell, CEO and chief technical officer of Xi
Graphics.  “With PC workstations using the E&S Lightning 1200LX
subsystem and our 3D Accelerated-X product, CAD/CAM engineers,
animators, 3D designers, and game developers have a very powerful
platform to create advanced 3D effects without trading off quality for
performance.” 

Evans & Sutherland has partnered with XiI Graphics to develop the
Linux driver.  XiI Graphics develops and markets, high-performance
commercial X display servers for use with Linux and UNIX operating
systems.  The company's base product line, the Accelerated-X brand of
X servers, is a stable, robust foundation for Graphical User
Interfaces that are often required for Linux and UNIX operating
systems installations that operate on a desktop or laptop computer. 

Hardware Vendors Support
E&S has also been collaborating with BOXX Technologies and TriStar
Computer Corporation to bring an open GL graphics board to the Linux
market that gives hardware users features such as quality shaded
performance and overlay plane support. 

BOXX Technologies
“We are excited to work with E&S to help bring high performance,
standards-compliant products to the Linux workstation space,” said
Todd Bryant, BOXX Technologies president and CEO. “We believe that
graphics acceleration is an integral part of Linux’s success on the
desktop.  With E&S Lightning 1200LX , users will have true OpenGL
acceleration on Linux platforms with top anti-aliased line quality,
overlay plane support, and shaded performance.” 

BOXX Technologies is a leading provider of hardware and software tools
for digital content creation and distribution on the Microsoft®
Windows NT® and Linux operating systems for the 3D, animation,
film, and HD broadcast markets. The BOXX suite of solutions, which
include 3DBOXXä, RenderBOXXä, and FusionBOXXä HD, are
complete systems for 3D, rendering, film, and HDTV.  Fortified with
E&S’s accelerators, BOXX workstations greatly reduce production
times and increase output quality.

TriStar Computer Corporation
According to Patrick Maderia, president & CEO, of TriStar Computer
Corp. “TriStar Computer is excited about the addition of Linux
support by E&S. We have been supporting Linux on our Workstations and
Servers for the past 12 months and believe that E&S is showing great
foresight in leading the charge into this market.”

TriStar is a privately held original equipment manufacturer of
high-performance Windows NT graphics workstations and servers.
TriStar offers four major product lines, with various models and
custom configurations designed to meet an array of user needs:
StarStation, PowerStation, StudioStation, StarServer. These systems
are custom built for professionals in graphics-intensive disciplines,

Software Vendors Support
Today, E&S is working with The Sense8 Product Line of Engineering
Animation, Inc. and Side Effects Software to ensure E&S Lightning
1200LX support for new Linux-based graphics applications.

Engineering Animation, Inc.
“E&S's Linux support finally provides the real-time 3D graphics
market with one of the first solid Linux hardware-accelerated graphics
solutions." said Tom Coull, Executive Director of EAI’s  Sense8
Product Line. “The demand for Linux support has been mounting,
inhibited only by the lack of viable 3D graphics hardware in the
marketplace. The combination of WorldToolKit and E&S' Linux hardware
opens an entire platform to 3D developers.” 

Engineering Animation, Inc.’s (EAI) Sense8 Product Line is the
leading provider of scalable real-time 3D interactive software
development tools. EAI is developing a Linux version of its
WorldToolKit simulation software, a portable, cross-platform software
development system used for building high-performance, real-time,
integrated 3D applications.

Side Effects Software
“Evans & Sutherland technology helped us to provide Houdini on
Linux as a viable platform for high-end 3D graphics," said Paul
Salvini, chief technology officer for Side Effects Software. "Their
ongoing commitment to quality Linux production solutions is evident in
the release of the Lightning 1200LX. We look forward to our continued
involvement with E&S to offer powerful solutions for the Linux
graphics community."

Side Effects Software, a world leader in advanced 3D graphics and
special effects software, announced the availability of the Linux
version of their product, Houdini 4.0 last week.  This new
Linux-compliant application offers the same look, feel, and feature
set as the IRIX and Windows NT versions of Houdini.

Pricing and Availability
