The purpose of this thesis is to show the application of modern digital techniques to produce a high speed computational system that has the capability of producing a faster than real-time model for the visual systems associated with flight simulator systems. A distributed/multiprocessing system was chosen due to the increased reliability, flexibility and throughput of the computational process. The system also has the advantage of providing increased modularity and ease of expansion. This research is firstly concerned with the development of a high resolution graphics system (providing a 1024 by 1024 point screen resolution), and the techniques for the production of moving visual scenes observed by a pilot when flying over a region of terrain in a flight simulator. In particular, this work is concerned with the real-time simulation of the aerodynamics of the aircraft and considers the problems of designing and accessing a data base which represents a model of the terrain. There are three major design considerations for the real-time CGI (Computer Generated Imagery) system of the type required. The first is to ensure that all processing for each picture frame is performed within a specified time limit. Secondly, the picture must have a realistic appearance and requires realism functions to be performed in real-time. The third design consideration is the cost.
