Abstract
Abstracthis thesis focuses on the construction of particle-based ocean waves, which can be applied to interact with the boat in physical simulation. The goal is to construct a real-time physical dynamic system of boat motion simulator for virtual reality application. We introduce a new method to create ocean waves with particle-based fluid. First, in order to simulate wind-driven ocean surface, we use a wind force model to simulate the effect of actual wind, and let the force act on the particle-based fluid to create waves animation. Additionally, fluid dynamics of waves are also influenced with gravity force or viscous force. The particle-based fluid simulation is based on SPH (Smoothed Particle Hydrodynamics) method, which is introduced in this thesis. Second, we consider the issue of drawing fluid surface, and present a new method to construct the surface with physically simulated cloth. Then we can create the interaction between solid, fluid, force, and surface to simulate the dynamics of the boat, and we can get more realistic results. Finally, this simulation can also be integrated with the 6 degree-of-freedom motion platform to build a ship motion simulator.eyWords: virtual reality, particle-based, ocean waves, wind, smoothed particle hydrodynamics (SPH), fluid surface, ship motion simulator
