Several Key Technology Research In The Dynamics Ocean Environment Simulation

With the development of computer technology, Virtual Reality technology in the Simulation of Industrial, Military, Games, Film and Television have an increased application, and the simulation of dynamic marine environment is significative ,also it is one of challenging task.It is a dynamic system for the ocean simulation,so it means that you can not find its borders.Dynamic includes two meanings:first,the wave is drived by the real-time wind data,and the effect of ocean if different if the wind is metabolic.Secondly ,the illumination rendering effects of sea surface is influcended by the sky background .The reflected effects of sun and clouds is changed corresponding the sky background .The contents of this paper:1. With the research by Philips'wave spectrum model, extraction of marine data, wind data on the ocean surface, generate wave height field with the FFT, build the grid of sea surface.The ocean shape is changed by accommodating parameters of wave model.2. The grid of sea without borderline is using LOD technology ,and viewpoint mobility programs in roll to achieve the simulation of infinite ocean.3. The ocean environment with the influence of sky by using GLSL.4. The ocean surface interactive features such as floating and sinking ship effect,wake simulation and rain and snow.Papers based on the results of the existing ocean simulation to improve and optimize the object in order to form a dynamics ocean simulation system which can be applied in the military and the meteorological field.
