What's New in VRSG Version 6

MetaVR has released Virtual Reality Scene Generator™ (VRSG™) version 6.3, which includes the ability for static culture models to cast shadows onto terrain and 3D oceans. This option is available on the new Shadows tab of the VRSG Dashboard. Also on this tab is the option to display planar shadows cast by dynamic moving models (ground vehicles and characters), which was previously located on the More Preferences dialog box. For this release shadows are cast onto terrain and 3D oceans only, not onto other objects.

Other new features and enhancements in VRSG version 6.3 include:

  • Improved HTC VIVE support with new options for using wand controllers with VRSG and for using the VIVE in augmented reality mode. Also support for user-developed VRSG plugins with a new VIVE controller function.

  • Improved Oculus Rift support with new options for using touch controllers with VRSG and for using the Rift in augmented reality mode. Also support for user-developed VRSG plugins with a new Rift controller function.

  • Ability for VRSG's H.264 video streaming plugin to be configured as a Real Time Streaming Protocol (RTSP) server, feeding streaming video to connected client machines.

  • New ability to change the color of a 3D ocean body for 3D ocean simulation. Also the ability to control ocean depth bias for simulations using narrow fields of view, like those used by UAV sensors where a larger depth bias is needed.

  • New 10-bit display support for use with monitors, projectors, and graphics cards that are high dynamic range (HDR) compliant.

  • New command-line options to auto-start VRSG in a customized visualization window and to control use of VRSG in tracking systems.

  • New visibility vertical scale option on the Environment tab, which changes the rate of visibility improvement as a function of altitude.

  • New ephemeris-calculated positions of stars in the night sky, with an option to scale star size.

  • New particle system features designed to better support tracer applications.

  • Improved light lobe rendering to potentially support up to thousands of lights.

  • New Model Viewer feature that generates commands for a cultural feature file that set a model's appearance, articulated parts states, and BVH animation.

  • New support for point feature instancing in the utility that converts OpenFlight terrain databases to MetaVR's round-earth terrain tile format (terrex-oflt2mds). This support
    improves both terrain conversion time and VRSG runtime performance.

  • New default directory for VRSG screen captures that are set to be written to a file.

  • Numerous performance optimizations.

VRSG Scenario Editor version 1.6 is delivered with VRSG 6.3.

 Recent updates to CONUS++ terrain

In parallel with the VRSG version 6.3 release, MetaVR has recently released new geospecific 3D terrain:

Three new high-resolution geospecific areas of interest to CONUS++ terrain:

The virtual terrain of Greater Denver, CO, is comprised of 439,379 geospecific buildings which were generated with Esri® CityEngine®. The models were exported from CityEngine in FBX format, and then converted to MetaVR's model format. The terrain of the area, including the modeled Buckley AFB and nearby Rocky Mountains, has over 4.5 million trees. For simulating night scenes, the terrain contains thousands of cultural light points of the airfield, Aurora, and Denver. This virtual training site is part of MetaVR's Southwest CONUS++ terrain dataset.

The virtual terrain of Greater Seattle uses source imagery of 1 meter per-pixel resolution blended and NED 1/3 (10 m) elevation data. The culture includes the popular Space Needle and 83,025 other buildings and 160,771 trees. The Seattle buildings (apart from the Space Needle model) were generated with Esri CityEngine using attributes from OSM data. This virtual city is part of MetaVR's Northwest CONUS++ terrain dataset.

Newly available virtual terrain of the rest of the world:

Australia and Oceania terrain, built from 3-arcsecond STRM elevation data (Guam elevation is 3 meters (NED 1/9) and imagery ranging from 0.60 to 15 meter-per-pixel (mpp) resolution. The Australia virtual terrain includes 0.60 mpp high-resolution natural color insets of many capital cities and others cities of interest.

North America terrain (apart from CONUS++), is constructed with natural color imagery ranging from 0.60 to 15 meter-per-pixel (mpp) resolution and with 3-arcsecond STRM elevation source data. Includes 0.60 mpp high-resolution natural color insets of insets of many capital cities and others cities of interest.

Additions to Asia and Middle East terrain to complete continent terrain coverage, with imagery resolution ranging from 15 meters-per-pixel (mpp) to 0.60 mpp insets of many capital cities and other areas of interest. Elevation is 3-arcsecond DTED level 1 and void-filled SRTM (Shuttle Radar Topography Mission) elevation data, subsampled to achieve a nominal 60 m post spacing.

Among the additions is a high-resolution, geospecific replica of the city of Kaliningrad, Russia, built with 0.60 mpp resolution imagery and DTED 2 elevation data, and cultural features totaling in over 17,000 realistic 3D building models, which were generated in Esri CityEngine using attributes from OSM data.

South America terrain, built from 3-arcsecond STRM elevation data and with natural color imagery ranging from  0.60 to 15 meter-per-pixel (mpp) resolution, the terrain includes 60 cm high-resolution natural color insets of many South American capital cities and other cities of interest.

All terrain was built with the latest release of MetaVR Terrain Tools for ESRI ArcGIS, version 1.4. Most culture was placed on the terrain with VRSG Scenario Editor, except for CityEngine-generated culture.

These terrain datasets are available in round-earth Metadesic format, are available for purchase to all MetaVR customers who are on active VRSG software maintenance and are US Government agencies or contractors (for official use only). For US-domestic use only, not available for export. The terrain will only run with a valid VRSG version 6.3 or greater software license with valid software maintenance.

 PREVIOUS RELEASES

VRSG version 6.2, released in April 2017, included:

  • New 3D ocean simulation, featuring realistic wave motion, multiple Beaufort sea states, 3D wakes, vessel surface motion, accurate environment reflections, and support for bathymetric data for shoreline wave shape and opacity
  • Over 300 new models (of which 187 are military) added to MetaVR's 3D content libraries since the release of version 6.1, bringing the total model count to 6,890.

  • New tracking support for the HTC Vive virtual reality system, SA Photonics SA-62 HMD, and SA Photonics stereo SA-92 augmented reality display.

  • Updated support for Oculus Rift CV1 HMD.

  • New startup parameter to disable VRSG's default pre-scanning of all folders in its search path.

  • Support for multiple blended microtextures, a new feature in the forthcoming MetaVR Terrain Tools for Esri ArcGIS version 1.4.

  • Ability to increase (10x, 100x) or decrease (10x) the playback speed of a recorded pdulog or scenario built with Scenario Editor.

  • Each screen capture is now saved with a corresponding viewpoint file, encoding the location of the screen capture in the scene.

  • Improvements to VRSG's policy on handling the ground clamping of culture models.

  • VRSG Scenario Editor version 1.6.

VRSG version 6.1, released in October 2016, put into the hands of VRSG users all the models in MetaVR's 3D content libraries at full resolution. The inclusion of 170 GB of 6,650 full-resolution models (including 179 new models since the release of version 6.0) provides the full benefit of rendering scenes in VRSG with MetaVR's highly detailed runtime models.

VRSG version 6.0, released in July 2016, contained several infrastructure updates, including full support for the Microsoft Windows 10 64-bit operating system, DirectX 11, Visual Studio 2015, and Nvidia’s new GeForce GTX 1080 gaming graphics card.

  • Full support for Windows 10 64-bit systems, to support customer integration efforts, in keeping with US Department of Defense (DoD) mandate for all the military services, Unified Combatant Commands, defense agencies, and field activities to upgrade their systems to Windows 10 by January 31, 2017.

    Click here for information about running VRSG 6 on Windows 7. (Note: Support for VRSG on Windows 7 ends on December 31, 2016.)

  • DirectX 11 support, which includes VRSG support for Pixel Shader Model 5.0. In addition, VRSG's plugin API now uses DirectX 11 objects. (Note: any user-developed custom plugin which drew graphics or otherwise interacted with the DirectX 9 Graphics API under VRSG version 5 will need to be modified to use DirectX 11 with VRSG 6.)

  • Built with Visual Studio 2015, which means that if a user-developed custom plugin extends VRSG's Dashboard interface with a property sheet, the plugin must be rebuilt
    with Visual Studio 2015.

  • Support for Nvidia’s GeForce GTX 1080 gaming graphics card, which delivers considerable performance enhancements.

  • Solid particle effects, which model projectiles with dust trails being cast from detonation events. These 10 new ballistic effects, located in VRSG's \Effects directory, all spew solid particles. Some effects thrust particles in a given direction that is denoted in the filename. The release also includes a new billboard flame effect.

  • Heat refraction post-processing effect for sensor views. This feature, available both on the Sensor tab of the VRSG Dashboard and via a fixed-length SetDataPDU interface, adjusts the simulated heat haze appearance of a scene when it is viewed through a layer of heated air (produced from conditions such as jet exhaust).

  • A total of 169 new models (including 121 new military models) were added to MetaVR's 3D content libraries. Among the culture models is a set of 7 trees now available with variants for all seasons. The models tree-163, tree-164, tree-cassia-001, tree-cassia-005, tree-elm-002, tree-elm-006, and tree-poplar-004 now offer 4-season variants on their appearance switch states.

  • Set of 14 high-resolution microtextures of a variety of dirt, sand, and grass geotypical ground textures. Many of the the textures were newly created for this release. VRSG blends a microtexture with the geospecific terrain imagery to produce the most realistic visual depiction of the terrain when it is viewed at close range.

  •  VRSG Scenario Editor version 1.4 with recent features that include the ability to assign damage effects to culture entities.

  • MetaVR’s tool for converting models from FBX model format to MetaVR format now supports new direction properties for the Rotating Animation custom attribute. DirectionX, DirectionY, and DirectionZ are three distinct properties that define mesh rotation around an arbitrary axis other than a primary axis.

  • Multichannel support is now part of the single unified VRSG executable, enabled with a check box on the Startup Parameters tab on the VRSG Dashboard.

  • Changed layout of the Startup Parameters tab on the VRSG Dashboard to improve specifying the location of terrain, models, scenarios and so on, for VRSG to load (VRSG's search path).
