Ship capsize accidents in extreme weather condition are difficult to predict, even though they cause a great number of casualties. When a ship capsizes, the most exigent decision-making and rescue schemes should be made to reduce the casualty. Numerical methods have been developed in ocean engineering to analyze the cap-size phenomena and to predict the possible capsizes. Visual simulation is adopted to proceed the evaluation of ship capsize accidents since it can augment the visual experience, facilitate the rescue measures, and easily validate the experimental results. The visual simulation can augment the physical evaluation of ship motion, and validation of the experimental results. However, engineering simulations of ship motion have less fascinating visual effect (VFX) compared with those in movie industry. In this thesis, visual simulation methods are pro-posed to generate the ocean surface which interacts with a passenger ship, and to add wave properties such as splash and wake using particle simulation method, to render the wave and its relevant stormy features, and finally to compose the visual effects together. The simulation can reduce the production time and cost of stormy wave with VFXs. The wave simulation is based on the modified Tessendorf grid method of wave simulation, and SPH particles are adopted to simulate the wave properties such as splash. Lastly, the integrated rendering is to produce the scene of ship motion in storm condition.
