600 Komas Drive News Release Salt Lake City, UT 84108 USA For Immediate Release 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, including: architectural design, mechanical design, engineering, desktop publishing, 3D animation, digital video editing, Internet web site development, video post production and software development. 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 The Lightning 1200LX solution is available this month for US $489 through E&S resellers/OEMs as well as ESDirect (www.es.com). Current E&S Lightning 1200 customers can upgrade to the Lightning 1200LX solution for $100. Upgrade information is available by calling 1800-show-me-the-penguin or through ESDirect.
