The Graphics and Video Laboratory of the Naval Postgraduate School (NPS) is in the process of constructing a three dimensional (3D) virtual world called NPSNET [Zyda91]. NPSNET is a low-cost, commercial workstationbased 3D visual simulator that utilizes SIMNET terrain databases and networking [Garv88]. NPSNET is programmed utilizing off-the-shelf SGI IRIS graphics workstation, rather than the platform specific nodes of SIMNET. Part of the work in constructing the NPSNET world is detecting and resolving collisions in real-time. Such collision detection and resolution has been accomplished and integrated into the latest version of NPSNET, NPSNET-2. The detection of vehicle- weapon, vehicle-vehicle and vehicle-stationary nonvehicle collisions is performed throughout the virtual world.
