Ocean Wave Reality Reaserch In The Virtual Reality

During the current computer simulating, it is the focus that generating reality object in computer vision fields, and in the area, the computer simulation of ocean wave is the most typical. While the force in the real world is certainly complicated, it’s hard to define their physical modal, so it raises the difficulty of the research during the ocean reality study. The work gives a method to generate ocean wave. Firstly, the trochoid function compose the physical model. And then, the grid system based on particle is proposed to cover the model. For the purpose of showing the real efficacy of ocean wave, the grid system is optimized, and based on this, the Split-Union method is proposed. The experiment shows that the method can simulate the ocean effectively.In the improving field of the gird surface, the article proposed a midpoint movement method, through the adding of the random movement factor, the surface of the model become cursory. This method is used to increases the concavity of the model surface. The adding of the movement factor is corresponding to the Gaussian distribution and let the model more realistic.In the regard of the combination of the gird and particle, the article use a method like the perturbation factors. It is used to split the ocean wave model in high-dimensional, which generate the bit-cylinder in the node of the model surface gird. The particle move randomly in each cylinder. The article proposes a method of eight-neighbor gird model and improve the delicate degree of the article’s movement. Through finding the mid-point of the micro-facets, the model can add the direction of the particle’s moving choice in controlling, Besides, it can avoid the high load of subdividing the gird excessively. It can improve the reality of the ocean wave model.Besides, the romance to the ocean light is illustrated by the detailed research. During this part, the refraction and the absorb of the light is analyzed. To be added, the cloud and atmosphere is added to the experiment for increasing the reality of the ocean wave.At last of the experiment, the drawing by Opengl of the experiment is given and it shows the fine efficacy of this ocean generating process.
