San Jose, CA, November 8, 1999 - Quantum3D(TM) Inc., the leader in PC-based interactive 3D visual computing systems, today announced AAlchemy(TM), a watershed realtime 3D graphics subsystem family for visual simulation and training applications. AAlchemy will offer the most scalable and advanced PC-based graphics capabilities to date, delivering full-scene, sub-pixel anti-aliasing with greater polygon throughput, a significantly higher fill rate, faster texture download, and improved image quality. The AAlchemy family, a subsystem of Quantum3D's Heavy Metal(TM) GX+ visual computing system, represents the third generation of Quantum3D's unique anti-aliasing technology. It couples Quantum3D's proven, patent-pending products with new architecture founded on upcoming graphics technology from 3dfx(R). AAlchemy will be launched at I/ITSEC, and can be ordered now via the Quantum3D Mercury(TM) Rising Program.

First PC-based Gigapixel Per Second Performance
AAlchemy will deliver scalable texture fill rates from 140 megapixels per second to greater than one gigapixel per second, depending on system configuration. AAlchemy features enhanced triangle and texture paging throughput to deliver industry-leading peak textured triangle rates and texture paging performance, capable of supporting 1280 x 1024 resolution or greater.

AAlchemy will employ T-Buffer(TM) technology, jointly developed by 3dfx and Quantum3D, which enables the graphics subsystem to deliver unmatched, full-scene sub-pixel anti-aliased image quality, along with previously impossible special effects that significantly enhance visual realism. The AAlchemy architecture approach will enable wide parallelism for single-pass, full-scene, sub-pixel anti-aliasing and deep parallelism for scalable fill rate. AAlchemy will also exploit the enhanced rendering and texture capabilities in the 3dfx chip to deliver 32-bit per-pixel color and Z, source, and destination alpha-blending, stencil buffering, advanced texture compression, enhanced transparency support, and advanced video capabilities.

"Quantum3D delivered the first open architecture PC-based visual computing systems with full-scene, sub-pixel anti-aliasing, and continues to deliver the best value solutions today for developers and integrators in visual simulation and training," said Rick Bess, Vice President of Marketing and Business Development for Quantum3D. "The AAlchemy family is the most advanced open architecture, scalable graphics subsystem to date. It is both a revolution in performance and value and an evolution of proven technology. AAlchemy demonstrates Quantum3D's continued commitment to meeting our customers' requirements and give them more choice than ever before."

General Information
Heavy Metal GX+ with AAlchemy is an open architecture, scalable system that enables single or multi-channel configuration and combines the most advanced industry-standard components with Quantum3D's value-added and patent-pending realtime 3D graphics technologies. Quantum3D systems are compatible with a wide range of leading realtime 3D scene managers such as MultiGen-Paradigm's Vega(TM), Soft Reality's SoftVR(TM), CATI's X-IG, and CG2's Vtree(TM) as well as Quantum3D's OpenGVS(TM); with 3D graphics APIs such as 3dfx Glide(R) and Microsoft(R) Direct3D(R); with realtime 3D file formats such as OpenFlight(R) and Terra Page(TM); and with leading operating systems. Leaders in visual simulation and training worldwide have already adopted Heavy Metal GX+ with Quantum3D's advanced graphics subsystem Mercury, delivering PC-based full-scene, sub-pixel anti-aliasing today. Applications developed on Heavy Metal GX+ Mercury systems will run on AAlchemy, enabling Mercury users to upgrade easily to AAlchemy's improved scalability, image quality, and performance. Participants in the Quantum3D Mercury Rising Program (details on the Quantum3D web site at www.quantum3d.com) will receive upgrades to AAlchemy.

Quantum3D will announce AAlchemy specifications on November 15th, and will start shipping AAlchemy in Q1 2000.
