MetaVR creates 3D real-time PC-based visual systems that provide the fidelity of geospecific simulation with game quality graphics for manned and unmanned air, land and sea military and commercial training simulation systems. MetaVR's software products enable users to build high-fidelity virtual worlds with our terrain generation tools and render the resulting virtual world with our real-time 3D visualization application, Virtual Reality Scene Generator (VRSG). VRSG is a Microsoft DirectX-based render engine that provides geospecific simulation as an image generator (IG) with game quality graphics. VRSG enables users to visualize geographically expansive and detailed virtual worlds at 60Hz frame rates on commercially available PCs. MetaVR’s 3D terrain databases cover the continents of Africa, Asia, Australia and Oceania, Europe, North America, and South America in its round-earth geocentric Metadesic format. All terrain datasets contain high-resolution insets of many areas of interest. Users can use MetaVR’s Terrain Tools for Esri ArcGIS for Desktop to turn their own geospatial data into real-time round-earth 3D terrain to render in VRSG. MetaVR's rendering technology uses advanced terrain and texture paging algorithms to render geographically specific imagery over expansive terrain databases while providing such advanced visual features as full-scene anti-aliasing and continuous level-of-detail morphing. On the Microsoft Windows platform, MetaVR delivers high performance, networked, real-time, single- and multi-channel visual systems with 3D content by fielding our software technology on the latest commercial PC-based 3D graphics accelerators. MetaVR VRSG is delivered with substantial libraries of 3D models, which are continuously updated and added to. These models can be used to populate VRSG virtual worlds with cultural features and to interact with networked vehicle, munitions, and character entities in real time in military simulation and training scenarios.
