NPSNET: an accurate low-cost technique for real-time display of transient events: vehicle collisions, explosions and terrain modifications

Abstract

This work concentrates on a method for real-time collision detection and how to resolve that collision when it had occurred. The results of this effort are only a small part of the overall system, NPSNET. The collision detection mechanism is integrated into the overall system to create realism involving collisions. The original NPSNET system did not contain a collision detection and response module. The collisions to be detected include explosions such as missile contact with a vehicle, one vehicle running into another such as a jeep and a tank, and terrain modifications such as an artillery round hitting the ground and creating a crater. The overall system complements the DoD large-scale networking system, SIMNET. The NPSNET system is portable and able to run on any graphics workstation that has the GL libraries.
