Abstract


With the increasing prosperity of China 's navy is growing stronger and maritime research ship wave arouse more and more attention . With the in-depth study of ship waves , ship waves Dimensional Visualization of new research topics . The three - dimensional visual simulation of ship waves is an integral part of the virtual marine environment , and to build a realistic three-dimensional ship waves have a wide range of applications in the military , engineering, games, advertising , and has important research value and application prospects . Thesis completed the work of the following four aspects : First, in the introduction of basic knowledge of the wave and the current wave analog common method based on three-dimensional visualization of the waves from the random wave structure model using the wave spectrum and fractal of simulation ; ship wave simulation . The ship wave from the classical Kelvin model simulation boat The traveling wave integral into the boat bow and the ship stern two boat bow portion of the water viscous ship waves consider inside , simulation more real ship waves ; in solving the integral equation the faster convergence Romberg integration method , and ultimately to achieve a three-dimensional visual simulation of ship waves ; third , introduces the mechanism of the formation of internal waves and turbulence ship within wave tail track . Introduction of turbulence on the basis of numerical simulation model commonly used to establish a simple model using MATLAB simulation model ; Finally, the simulation of natural phenomena of the sea environment . Fractal simulation use of OPENGL simulation of clouds , the sea fog , rain, snow simulation using the particle system , the simulation of the sea environment can enhance the fidelity and realism of the sea .
