MetaVR Delivers Virtual Ft. Wainwright Urban Warfare Training Site

MetaVR™ has delivered to Ft. Wainwright, Alaska, a 3D database of its Combined Arms Combat Training Facility, named after Pvt. Joseph P. Martinez.

Ft. Wainwright supports simulation training of dismounted infantry and UAV ground control, as well as training on the Stryker Battle Command Skills Trainer (BCST) vehicle simulators. The database is used to train infantry combined arms units for Military Operations in Urban Terrain (MOUT).

The 3D simulated urban warfare terrain database of Ft.Wainwright was created with MetaVR's terrain generation tools. The MOUT site area cultural features were modeled a 3D modeling application and exported to MetaVR's model format.

Included in the database are 16 hybrid photorealistic, photospecific MOUT building models with interiors and articulated doors. These models and models of other structures were created from perspectiveless digital photographs of the structures at the actual MOUT site. The building models have radiosity (soft shadows) applied to the geometry to increase their realism. The MOUT site details include an underground drainage system, which is modeled from tunnel entrances and includes the associated underground concrete pipe network. The database makes extensive use of cultural elements such as street signs, power transformers, street lights, curbs, bleacher seats, gas pumps, oil drums, fences, flag poles, portable restrooms, utility cables, a picnic table, and a surveillance camera. All models are in MetaVR’s model format.
