MetaVR Visuals Used in Convoy Simulation Training

MetaVR™ real-time visual systems are in use for convoy training on the Warrior Skills Trainer (WST) at Ft. Hood, TX , Ft. Carson, CO, Ft. Stewart, GA, and Ft. Riley, KS. The WST simulator is comprised of several simulation models that enable units to train for convoy-related tasks. Each MetaVR delivery included Humvee models in the 3D content military entity library.

The above images show a rendering of a convoy simulation using the MetaVR Virtual Reality Scene Generator™ (VRSG™), on a database created by MetaVR. The terrain represents a built-up urban area outside the Baghdad airport that includes narrow passages between buildings and ongoing construction. All models are from the baseline model set of the 3D content library delivered with VRSG. In the inset view, troops are engaged in simulated convoy duty using a customer supplied terrain database.

The images above show the Warrior Skills Trainer (WST) on the right being used to prototype troop configurations within the vehicle. The inset image on the left shows the view that a driver would see from inside the HMMWV with the complete interior modeled. This view is from inside the third vehicle from the front of the convoy scene shown at the top of the page. Above WST image courtesy of III Corps.

WST provides a field initiated prototype training environment for units to practice convoy Tactics, Techniques and Procedures (TTP) before live training or as refresher training.

The WST consists of three simulators of High-Mobility Multipurpose Wheeled Vehicles (HMMWVs) in which trainees drive through a virtual representation of Baghdad and surrounding areas, in a manner similar to driving in a video game. Trainees can communicate with each other and with their facilitator in the simulation control area through headset communication networks.

As described on Ft. Carson's web page about its Convoy Skills Trainer, HMMWV driving, communications and other capabilities are supported by the JCATS simulation. All friendly, enemy and non-combatant events that occur while driving are produced by JCATS and its interaction with the virtual driving system; this system consists of the National Simulation Center’s “Commander’s Workstation” and MetaVR VRSG. Each HMMWV has joysticks for rotating the driver's view, a laptop with software to track the driver's movement in the simulation and a corresponding map to help navigation. Each HMMWV is also equipped with a mixture of two simulated individual weapons and a simulated crew-served weapon provided by the Engagement Skills Trainer (EST), which trainees use to engage the enemy in a gunnery scenario linked to the driving scenario.

Based upon soldier feedback, MetaVR subsequently worked with Cubic Corporation to upgrade its Engagement Skills Trainer (EST) visuals to use VRSG visual systems. The small-arms training simulation, which features human animated characters, had been running as a standalone application on EST-2000 devices. Part of the upgrade effort entailed networking the EST system such that it would integrate with the WST convoy trainer.

As result of the integration, training with networked convoy and gunnery simulations occurs in a seamless, more realistic manner; for example from within a scenario a convoy driver and other vehicle occupants can react defensively and return fire if the vehicle is under attack.

The following diagram depicts a proposed upgrade for the WST convoy simulator. This second generation implementation of the WST device, as proposed by Ft. Hood, is in operation at Ft. Carson CO, with 12 MetaVR visual systems. (Diagram courtesy of III Corps.)
