An Ocean Wave Simulation Research Based on Controllable FBM Model

Tower simulation system which is a realistic 3D real-time simulate training system has been traded widely, and it brings new requirements, simulating sea and water realistically in real-time. The paper studies classical sea simulation model all of the world, educes the conclusion that those classical models can´t meet the requirements which are fast computation, realistic vision, the capacity to control ocean, square-built offing. According to requirements, the article introduces a controllable FBM model to simulate ocean. The leading thought is combining height field of FBM model with Gerstner models´ linearly. It is proved that the controllable FBM model has good randomicity and fast computation, at the same time, since it combines 3D Gerstner model, it becomes a model which can control the ocean easily and can produce different ocean states, to show the effect of wind. Compare with other models, the controllable FBM model can produce more real waves, fluent film, obvious wind direction, no less than six levels of state of the sea.
