I/ITSEC 2017: MetaVR Demos VRSG’s Newest Visual Fidelity Features

MetaVR and business partners exhibit products and technology

On booth #1249 at I/ITSEC, MetaVR showcases its terrain and visualisation products and technologies that support applications ranging from unmanned air system (UAS) operator and Joint Terminal Attack Control (JTAC) training, to high-speed fixed-wing cockpit simulators, to littoral and marine-based operations to individual/first-person ground-level urban operations. All terrain demos will be rendered in the latest version of MetaVR’s core product, Virtual Reality Scene Generator (VRSG). 

MetaVR demonstrates VRSG’s newest visual fidelity features including shadows cast from static culture models, screen space ambient occlusion (SSAO), and several enhancements to 3D ocean simulation. 

MetaVR also demonstrates two new 3D terrain datasets, built in METADESIC round-earth format with the latest version of MetaVR Terrain Tools for Esri ArcGIS: 

– High-resolution geospecific Operation Blended Warrior (OBW) terrain dataset of California, Washington and portions of Nevada and Arizona, including modeled areas of Greater Seattle, Camp Pendleton with Kilo 2 and Combat Town 25 MOUT sites, and the Leschi Town combined arms collective training facility (CACTF) at Joint Base Lewis McChord (JBLM). MetaVR has provided this terrain to participants in the OBW LVC event who is running MetaVR visuals in their simulators. 

– Greater Seattle uses source imagery of one metre per-pixel resolution blended into and NED 1/3 (10m) 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. The models were extruded and textured from OpenStreetMap (OSM) data, exported from CityEngine in FBX format, and then converted to MetaVR’s model format. 

– The virtual Leschi Town training site of 25sqkm was built with 15cm per-pixel resolution USGS imagery blended with 1m per-pixel NAIP imagery surrounding the area up to Seattle. Elevation source is USGS 1m LIDAR blended with USGS NED 1/3 (10 metres). The virtual facility features 52 geospecific building models with interiors, multiple levels, and articulated windows and doors. These models, together with over 100 models of other cultural elements, were created from publicly available photos and videos and geolocated on the terrain footprints. Over 27,500 tree and vegetation models round out the scene. 

– High-resolution geospecific virtual Buckley Air Force Base (AFB) and the dense urban environment of Greater Denver, CO. The virtual terrain was built with 15cm per-pixel resolution USGS imagery blended into 1mpp underlying NAIP imagery and NED 1/3 (10m) elevation data. Airfield culture includes the runways, runway lights and signage, a geospecific control tower and 24 other geospecific building models, plus other cultural elements, geotypical volumetric trees, and light points. Geospecific culture models were created from publicly available photos and geolocated on the terrain. Surrounding the modeled Buckley AFB is terrain of Greater Denver, comprised of 439,379 geospecific building  models generated with CityEngine from OSM data. The terrain of the area, including the nearby Rocky Mountains, has over 4.5 million trees. For simulating night scenes, the terrain contains thousands of cultural light points. This terrain is also on display at the Immersive Display Solutions’ (IDSI’s) booth #1273 on the latest Sony Crystal LED (CLED) technology, which features exceptional black levels and a contrast ratio of more than 1,000,000:1 in a scalable 4.8×1.8m curved configuration. 

Other demonstrations in the booth include: 

– JTAC training. MetaVR and Battlespace Simulations’ (BSI’s) JTAC desktop simulation system (accredited by JFS ESC and STANAG) are set up for conducting close-air-support training exercises with Close Air Solutions, instructors with relevant domain knowledge. In addition to providing the out-the-window views and UAS HUDs, VRSG provides the simulated thermal views, simulated UAS video feed on the JTAC’s ROVER device, and emulated military equipment views. The training scenario takes place on MetaVR’s geospecific Kismayo 3D terrain and tests JTAC, UAS, and aircrew in a complex mission environment with 5-Line, 9-Line and Call-for-Fire interfaces generated from BSI’s Modern Air Combat Environment (MACE) software. The simulator’s 4m 220° curved display is provided by Immersive Display Solutions. 

– High-resolution geospecific 3D terrain of the Somalia port city of Kismayo. A relevant geospecific terrain for coordinated UAS and JTAC close-air-support training, this 3D terrain is populated with hundreds of geolocated, photo-specific culture models built from ground-level photographs taken on the streets of Kismayo. Demo scenarios include amphibious and close-air-support missions. The amphibious scenario highlights VRSG’s 3D ocean simulation and MetaVR’s growing collection of US naval models. 

– High-resolution geospecific 3D terrain of a mountainous region in Kabul province, Afghanistan. The modeled village of Khairabad includes 650 custom-built 3D structures that match footprints on the source imagery. Many structures have multiple damage states, demonstrated in scenarios that feature close-air-support missions with UAS overwatch and strikes, and pattern of life activity. These scenarios contain many of MetaVR’s newest military ground vehicles. 

– High-resolution geospecific 3D terrain and modeled airfields in Continental US plus Alaska and Hawaii (CONUS++). The CONUS++ demos include flythrough sequences on 27 modeled airports and airfields, with high-resolution imagery and geospecific and geotypical cultural content. 

– SUAS for collecting sub-inch geospecific imagery for real-time 3D terrain. The MetaVRC, MetaVR’s SUAS for imagery data collection, is on display. Built for autonomous aerial surveying, the MetaVRC captures 2cm per-pixel resolution images that can be used with accurate elevation data to compile terrain at 2cm resolution. The resulting synthetic environment can then be rendered in VRSG. 

All terrain was built in MetaVR’s round-earth METADESIC format with MetaVR Terrain Tools for Esri ArcGIS. All of MetaVR’s real-time demos were created with VRSG Scenario Editor, using substantial cultural feature, character, and land, sea, and air vehicle assets, and 3D character animations from MetaVR’s 3D content and animation libraries of over 7,000 models and over 1,400 animations.
