Virtual Reality Scene Generator (VRSG)™

The Virtual Reality Scene Generator (VRSG)™ is a state-of-art, real-time 3D computer image generator (IG) that enables you to visualize geographically expansive and detailed virtual worlds on Windows PCs. VRSG provides real-time, single- or multiple-channel visualization of virtual environments, dynamic moving models, and special effects, using Microsoft DirectX commercial standards.

VRSG is a component of MetaVR's rapid virtual world terrain creation and visualization technologies. With MetaVR's products, you can build and visualize, at 60Hz frame rates, virtual worlds created with real-world photographic imagery, elevation, and feature data.

You can use VRSG as:

• A dedicated computer image generator, coupled to an external simulation host in single- or multiple-channel mode.
• A standalone DIS or HLA stealth visualization tool.

VRSG software is Microsoft-based; it uses Windows, DirectX, and is written in C++. The following is a partial list of VRSG features:

• Multi-channel synchronization
• Integrated support for animated 3D characters
• Multiple degree-of-freedom hardware tracker support for controlling the position and/or orientation of the VRSG viewpoint
• Full-featured, high performance light points and light lobes
• Ability to exploit a multiple-CPU computer to support asynchronous paging of both terrain geometry and texture
• Multiple mechanisms for adding 2D overlays to the 3D display
• Unlimited number of viewports per channel
• Virtual world sound generation system

MetaVR's terrain and texture paging technology enable you to depict ultra-realistic virtual worlds derived from gigabytes of actual aerial imagery and elevation data.

You can run MetaVR VRSG on a variety of computers that use Microsoft Windows operating systems, from a notebook computer, a 2-unit game computer, to a 1-unit desktop computer using a current commercial graphics card and a Windows XP 64-bit system.

Each new VRSG software license is delivered with a 160 GB Western Digital hard drive that contains the following databases in MetaVR's MDX format: Ft. Campbell, Ft. Benning, Ft. Irwin (NTC), Ft Lewis, and Greater Baghdad, Iraq.

MetaVR provides products that complement VRSG, among them Metadesic Compiler™ and WorldPerfect™, rapid 3D terrain-creation systems that uses elevation points and imagery as source data. These products work hand-in-hand with VRSG to provide rapid terrain creation and high-speed visualization.

You can order the VRSG application directly from MetaVR.
