| Summary: | 碩士 === 國立臺灣大學 === 電機工程學研究所 === 96 === The goal of this thesis is to construct a real-time physical dynamic system of speed boat driving simulator for virtual reality application. We present several new methods to promote the last simulator system both physically and graphically. The simulation system is divided into three subsystems, the ships dynamics system, the hydrodynamics system, and two ways coupling between them. We apply hydrodynamic and mechanics to simulate the ocean surface and ship model respectively. In this thesis, the following factors about wave decays are taken into consideration: waves propagating velocity due to sea floor terrain, wave generated by object floating on the ocean, and reflection of wave due to conflict with the ship. On the other hand, the ship would be affected not only by buoyancy but also viscosity, current, wave and damping. We render the ocean surface by Graphics Process Unit (GPU) hardware to reach the visual realism. Finally we integrate this algorithm with a 6 DOF platform and construct a virtual ship driving simulator. By this way, we can achieve the desired realism, and complete the virtual reality environment.
