San Jose, CA - January 23, 2002 - Quantum3D® today announced that Quantum3D's OpenGVS™ realtime 3D scene management software (Version 4.4.1) has been optimized for use on AMD Athlon™ and AMD Athlon MP processor-based platforms. AMD-optimized OpenGVS provides 3D visual simulation and training developers with industry leading performance and outstanding performance for PC-based deployed applications.

The OpenGVS 4.4.1 releases have been optimized and tested with systems using AMD Athlon processors across a spectrum of real-world PC-based realtime 3D application development scenarios. For texture paging applications, the OpenGVS Large Area Database feature, which supports both Terrex TerraPage™ and Multigen-Paradigm OpenFlight™ formats, has been tested using dual AMD Athlon MP processors. Quantum3D found that AMD Athlon and AMD Athlon MP processor-based platforms meet the Company's high standards for performance with OpenGVS.

"For the past several years, OpenGVS has maintained and enhanced its position as one of the most popular and powerful, multi-platform realtime 3D application tools available," said Ross Q. Smith, Quantum3D co-founder and vice president of sales and marketing. "With the success of AMD Athlon processors in the high-performance PC market, we have seen strong interest in our user community for AMD optimized support, so our efforts address an immediate need in the simulation and training community. We are committed to ensuring OpenGVS availability on multiple platforms, and are pleased to work with AMD to deliver optimized OpenGVS on their popular processing platforms."

"Quantum3D's certification and optimization of AMD Athlon and AMD Athlon MP processor-based systems helps ensure that users of OpenGVS have a solid platform for their 3D development needs," said Richard Heye, vice president of Platform Engineering and Infrastructure for AMD's Computation Products Group. "Developers know that system I/O, memory and floating point performance is critical for optimal realtime 3D application development, and AMD delivers maximum performance for OpenGVS."

About OpenGVS
One of the most popular and portable scene management tools in the realtime graphics marketplace, OpenGVS is a comprehensive, open-architecture, realtime 3D scene management system that has been widely used since 1990 by leading systems integrators and ISVs, including Adacel, Boeing, Aerobel, SDS International, Honda, Renault, Lantech, Ship Analytics, NorControl, KQ Systems, ECC and others to develop and deploy a wide range of realtime synthetic environment simulation and training applications.

Built on top of OpenGL® 1.3, 3dfx® Glide™, Quantum3D SimGL™ and Microsoft DirectX™ foundation-level graphics APIs, OpenGVS enables RISC workstations and Microsoft® Windows® and Linux-based PCs to host advanced synthetic environment visual simulation and training applications by providing the higher level functionality and resource management required in complex simulation applications, while delivering peak performance from the underlying system and graphics hardware. OpenGVS' object oriented design features a complete library of 800 essential simulation functions with facilities for managing cameras, channels, atmospheric effects, frame buffer operations and effects, texture, geometry, objects, scene level features, level-of-detail and special effects. OpenGVS supports both display list and immediate mode operations, and includes extensive SSE™ optimization for maximum performance on Intel and AMD Athlon architecture systems. Recent enhancements to OpenGVS include Fade Level of Detail, support for Elumens™ Spherical Projection Images (SPI) distortion correction and improved multi-threaded support for texture paging of both TerraVista™ and OpenFlight format databases. Employing OpenGVS enables simulation and training system integrators and ISVs to concentrate on critical project requirements such as 3D database development, equations of motion, host integration and special effects, instead of re-inventing the wheel on basic graphics programming and resource management.

OpenGVS is both portable and affordable, with volume runtime pricing (including free runtimes on all Quantum3D system products) and scalable SDK packaging that lets developers license the technology they need.
