Abstract
Spatial knowledge, often used in military operations, is a significant component of military skills. It includes knowledge of the relationships of one object to others, the movement of objects relative to others the relationship of the human to each of the objects, and this involves perception and awareness of the humans' position within the situation. Key ingredients include both time and distance perceptions by the human'Recently, the military have been exploring the use of virtual environment technology; the focus for training systems has been on simulation of the environment and behavior of the objects from a mathematical modeling perspective.This paper will examine two of the major factors involved in Performance Metrics for use within Virtual Environments the focus of this research will be performance measurement of the training environment using US Naval case studies, implementing geometric modeling.
