碩士 === 淡江大學 === 資訊工程學系 === 85 === A simulator is the system that combines the technologies of computer graphics, multimedia and mechanical control to create a virtual environment. In order to let the user fully immerse into this synthetic environment, system must be able to process computer image, sound effect and mechanical control in real time. As the increasing complexity and higher realism of virtual world requested by the user, the need of high performance computing becomes demanding. Such as mainframe and special purpose computer are traditionally used to construct a simulator, whereas those computers are expensive. As the evolution of computer technology, both PC and workstation are gaining more power with less cost. Therefore, coordinating multiple PCs or workstations over network to construct a distributed computing environment to meet the requirement of high performance of computation is the trend of recent research. Analyzing the tasks of a simulation systems, potential parallelism exists among following modules: graphics render, user interface, sound effect, virtual world manager, high fidelity models and dead reckoning models. The motivation of this thesis is to design a distributed computing environment to fully explore these potential parallelism with pipeline mechanism to speedup the simulating process. The simulation system presented in this thesis, which is based on RTI (Run- Time Infrastructure) of HLA (High Level Architecture) purposed by Department of Defense, is actually built over distributed PCs. The goal of this presented system is attempting to approach parallel computation with distributed computation environment as required by high performance computing. Further, different components can be mounted on this system to form another simulation for other purposes. In other word, the system presented in this thesis provides a way to construct a modulized simulation system easily.
