Abstract : In developing line of sight target acquisition software two approaches have been explored. The first was an object based system (Young and Whitney). Next, and more recently, has been the implementation of a database driven simulation. The heart of this implementation is the Perspective View Generator (PVG) developed for the US Army by Wolfgang Baer. This implementation suffers from two fundamental shortcomings: low frame rates and unrealistic representation of target vehicles. This paper concentrates on using more powerful, multiprocessor work stations to improve frame rates. The paper also addresses possible methods for representing vehicles in this multiprocessor environment.
