Dassault Systèmes Unveils Premiere Development Authoring Platform For High-Quality 3D Game Production

San Francisco, CA - February 20, 2008 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D solutions, today announced the release of 3DVIA MP, a comprehensive development platform with a realistic real-time rendering engine for PC and Xbox 360 TM . 3DVIA MP will significantly improve the game development process by quickly bringing ideas into reality and aiding developers in producing high-end, 3D multiplatform games. 3DVIA MP for PLAYSTATION ® 3 (PS3 TM ) and Web deployments will become available in the summer of 2008.

"3DVIA MP is an outstanding development engine that has given our team a collaborative work environment, including low-level access for our programmers," said Nicolas Gaume, CEO of Mimesis Republic game studio. "The designers have been able to get results in record time while maintaining triple-A visual quality."

3DVIA MP strengthens and extends the philosophy and functionality of the Virtools 4 product line. Established in 1999, Virtools 4 technology, known for its unique behavioral engine, is the standard for game prototyping, casual games production and industrial applications, both online and offline. The all-new platform, 3DVIA MP, complements the IP creation process and leverages its signature behavioral engine with the capacity to exploit the power of the Xbox 360 and PS3 TM in production. 3DVIA MP provides a high-end, realistic real-time rendering engine, which serves as the native support for multi-core processing, advanced shaders and lighting, and the depth of a full multiplatform production framework, allowing larger teams to collaborate.

"3DVIA has taken into consideration studios' needs when designing and developing games, especially those that work with large development teams in multiple locations," said Bertrand Duplat, Virtools founder and CTO, 3DVIA, Dassault Systèmes. "Our new development engine encompasses the entire development cycle - from importing content to testing and debugging - maximizing publishers' investments by allowing them to create content once, optimize it, and publish it across multiple platforms."

3DVIA MP is available in two forms:

- 3DVIA MP Prototyping for creative teams to build prototypes on PC and test them directly on target platforms (high-end PC, Xbox 360 and PS3 TM )

- 3DVIA MP Production is the complete and flexible integrated production pipeline designed for multi-platform game development projects.

"3DVIA, the most recently introduced brand of Dassault Systèmes, establishes 3D as a universal medium. DS is committed to working closely with game developers as part of its long-term strategy," said Lynne Wilson, Senior VP and General Manager, 3DVIA. "The game industry continues to push the envelope in innovative 3D visual and experiential technologies. By addressing the needs of its game developer customers, DS also leverages game industry knowledge and experience to deliver a set of exciting, highly realistic consumer online applications for broader business uses."

3DVIA MP will be showcased at the Game Developers Conference in San Francisco February 20-22. Show attendees can attend live demonstrations at the 3DVIA booth, located at the Moscone Center North Hall, Booth #6034. More detail about 3DVIA MP can be found on its Web site at www.3dviamp.com.
