Research On Computer Simulation Of Ship Waves

With the Chinese navy's increasingly powerful and increasingly prosperous shipping, research on ship waves was paid more attention. As the ship waves in-depth study Three-dimensional visualization become a new study. Ship waves of three-dimensional visualization of simulation are an integral part of the virtual sea environment. And build realistic Three-dimensional ship waves in the military, engineering, games, and advertising in a wider application. The study has important research value and application prospects.The paper in the following four aspects of the research field is performed. Firstly, the paper presents a method of simulating Three-dimensional waves based on random wave mode and wave spectrum, and then it uses the wave spectrum and fractal approach to control sea waves. Secondly, it's simulation of the ship waves. In the simulation of the ship waves, beginning with the classical Kelvin model and the ship waves' integral was divided into the bow and stern. In the integral the viscous impact of water around the bow to ship waves was taken into consideration. All of these make the ship waves simulation more realistic. In Solving the integral equation the convergence of high-speed Romberg integral method was used to realize the Three-dimensional visual simulation of the ship waves. Thirdly, introduce on the internal waves and turbulence formation mechanism, introduce on the Numerical Simulation of Turbulent commonly used model, to perform a simple model of turbulence and using MATLAB to simulate it. Finally, it's simulation of the simulation of the natural phenomena on the sea surface, using fractal approach to the simulation of the clouds, using OpenGL to simulation of the fog, using particle system to simulation of the rain and snow. All this simulation can enhance the fidelity and realistic of the sea environment.
