MetaVR Announces the Release of MetaVR Virtual Reality Scene Generator (VRSG)
Version 5.6.

Version 5.6 of MetaVR Virtual Reality Scene Generator (VRSG) is available for immediate download to customers on active software maintenance. VRSG version 5.6 contains the following new features, enhancements, and 3D content:
  • Enhancements to VRSG's digital video streaming capability. VRSG's MPEG output has been expanded to include the H.264 compression output format. VRSG can interoperate with hand-held video receivers such as the ROVER device, to provide a simulated UAV video feed such as is used in Joint terminal attack controller (JTAC) training.
  • Ability to run a VRSG session in stereoscopic vision to enhance the illusion of depth, for a more immersive 3D experience.
  • New sensor post-processing effects to include:
    • Depth-of-field, representing an improvement of existing blur filter.
    • Dynamic range washout effect.
    • Improved random noise effect.
    • Motion blur effect.
    • Ability to stimulate each unique section of an entity to generate a thermal response.
  • New Sensor tab on the Dashboard for controlling post-processing and rendering effects of the VRSG IR scene display, such as the amount of noise or blur, the level of intensity of the terrain or vehicles, and whether to display simulated A/C banding. This tab consolidates sensor options previously located elsewhere on the Dashboard and makes visible sensor options previously available via a programming messaging interface.
  • Several enhancements to First Person Simulator (FPS), to support the use of VRSG for JTAC simulation training. VRSG is now integrated with the Logitech Dual Action Gamepad for FPS functions. Using the gamepad with a new game-like interface for FPS, you can manipulate a character's movements and access various functions such as laser ranging, target designating, or firing on a target. FPS is now available in VRSG Metadesic. When FPS is used with a head tracker, the second monitor output on an NVIDIA video card can be used to render the scene for a simulated laser rangefinder/designator device. VRSG is now integrated with simulated GLTD II and Mark VII devices and off-the-shelf virtual moncular/binocular devices to enhance the fidelity of JTAC training. When VRSG FPS is displayed in NVG sensor mode, you can display and manipulate an IR pointer to mark a target for others to view in NVG sensor mode.
  • Support for several additional CIGI 3.2 messages.
  • VRSG integration with Logitech Dual Action Gamepad as a secondary device for simulating UAV camera payload and flying 3D terrain in fixed-wing mode, as well as for FPS characters as described above.
  • Integration with Scalable Display Technologies for edge-blended, distortion-corrected, multiple projector displays on arbitrary-shaped surfaces.
  • New plugin for display systems requiring simple edge blending and distortion correction. With this tool, you can manually move control points for distortion correction and use the polygon masking and eraser tools for edge blending.
  • Ability to display a compass rose in the visualization window.
  • VRSG integration with InterSense InertiaCube3 tracker.
  • An alignment model for aligning the projectors/displays of multi-channel systems.
  • New plugin entry point for vertical retrace notification. This feature is useful for plugins that need a reliable timing signal.
  • New anti-aliasing control on the Dashboard for easily changing the anti-aliasing level or turning off anti-aliasing during a VRSG session.
  • The removal of the mouse cursor from the visualization window (in windowed mode) after a period of inactivity.
  • Persistence of the Startup Parameters tab on the Dashboard, in read-only mode, once a database or a set of terrain tiles has been loaded in the visualization window.
  • MetaVR's 3D content libraries now include over 130 new military vehicle models including several Iranian aircraft models, over 50 new radar models, and new modeled interiors in all the models of Mine Resistant Ambush Protected (MRAP) production vehicles. In addition, the version 5.6 libraries contain over 100 new cultural feature models. All models are now delivered in MetaVR's HPY format. HPY files are compressed binary files that store all data associated with a given model. In particular, an HPY model file contains all of the textures referenced by that model, which eliminates the need to maintain a separate set of associated texture files along with each model. HPY models can be used in exactly the same manner as HPX format models. VRSG and MetaVR's Terrain Tools continue to support the HPX model format. MetaVR's OpenFlight conversion utility, which is installed with VRSG, continues to convert models from OpenFlight format to HPX format.
  • New Afghanistan demo database. This 3D geospecific Afghanistan terrain covers 9,600 square kilometers of the Afghan province of Kabul. This terrain features a high-resolution village with over 500 buildings, based on the small village of Khairabad in the southern part of the Kabul province. Delivered with the Afghanistan terrain are several real-time VRSG scenarios depicting ground combat simulations such as sniper, IED detection, and forward air controller or JTAC missions. This database replaces the Baghdad terrain database which was delivered with previous releases of version 5 of VRSG. The Afghanistan database is also now available in OTF format.
  • Enhanced multi-texture support for models created in Presagis Creator. New supported multi-texture effects include shadow maps, light maps, and decals.
  • Improved track animation to enable independent movement of track directions and speeds for each side of a tracked vehicle entity which provides a realistic representation of a turning tracked vehicle.
  • Ability to assign enumeration-specific particle effects (such as contrails) in the ModelMap.ini file.
  • Ability to edit and reload a ModelMap file during a VRSG session.
  • New search path behavior for loading models on a rendered database. VRSG will now search a user-created directory MetaVR\VRSG 5\Models\User recursively. Now users can store their own content in a VRSG subdirectory while keeping their content separate from VRSG's native content.
  • Ability to preview the firing effects of armed vehicle models in the MetaVR Model Viewer application.

MetaVR continues to implement customer requested software features at no additional cost beyond the license purchase and the annual software maintenance fees. Many features in the VRSG version 5.6 release were developed as the result of customers' requests, at no additional charge.

Version 5.6 of VRSG is available for downloading to customers on active maintenance. Contact for further information.
