Demonstration of Virtual Dynamic Craters
Back to MetaVR Videos

This VRSG video shows MetaVR deformable virtual terrain with dynamic craters with solid particle effects rendered in Virtual Reality Scene Generator™ (VRSG™).

VRSG has the capability to dynamically deform terrain surfaces to represent craters resulting from munitions impact.  Users can associate various crater radius and depths with differing munition types.  On receipt of a detonation event, VRSG can dynamically hypertessellate the local terrain surface to the degree needed to capture the crater's shape.  This process happens in real-time without interruption to VRSG's 60 Hz update rate.  The newly formed crater will support missions functions such as elevation lookups and intervis queries.  For infrared (IR) modes, the crater will appear hot in the physics-based IR rendering, with incremental cooling over time, from the outer radius inward.

The synthetic 3D terrain is of the Prospect Square area of the U.S. Army Yuma Proving Ground (YPG). The 2 cm per pixel resolution imagery that MetaVR used to build the virtual Prospect Square was captured by the company's portable UAV. The MetaVRC portable UAV was built and flown by Swift Radioplanes in military controlled air space. With both the imagery and 2 meter elevation data, MetaVR compiled full-resolution (2 cm) terrain tiles of the area with MetaVR Terrain Tools for Esri® ArcGIS® in MetaVR’s round-earth Metadesic™ terrain format.
