Abstract
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.
