Development of a Three Dimensional Terrain Display for a Light Infantry CombatModel

摘要

As an augmentation to field training, the author identifies a need for an easilyavailable light infantry platoon combat model that presents a realistic view of the battlefield environment. To meet this need, the author examines the feasibility of developing a realistic three dimensional display of a terrain representation on a personal computer. The target computer provides only limited graphics support with an Enhanced Graphics Adapter and all graphics routines are implemented in software. Three methods of terrain representation are examined, and the Dynamic Tactical Simulation (DYNTACS) terrain model is chosen for implementation. The DYNTACS representation uses a specialized triangle drawing procedure written in assembly language, the painter's algorithm for hidden surface removal, and Defense Mapping Agency Digital Terrain Elevation Data. The implementation obtains a display rate between 1.2 and 1.5 seconds on a 80386 based 25 MHz computer. The author concludes that with the addition of enhancements that provide the capability to display cultural features, and model the target acquisition process, the program could be developed into a light infantry platoon combat model or a research tool for examining effects of human factors effects on tactical decision making.
