Simulation of 3D dynamic seas based on OpenGL

摘要

In this paper, we analyzed the dynamic display of 3D seas simulation. And we proposed a method of dynamic simulation using OpenGL. First, we build a three-dimensional grid of sea level, and establish the mapping between horizontal and vertical coordinates, so that we can use LOD to improve efficiency. Second, we use a plurality of superposed sine-waves of different directions to initialize the height of each grid point, to make sure the different forms of each column of the waves. After that, we use the timer function in MFC to circulate the height value one by one in the column to simulate moving waves. The experimental simulation has proved that a photorealistic model of waves can be reached using sets of superposed sine waves of different directions, and the technique of LOD optimizes computing efficiency. So real-time performance is improved without effecting the quality of modeling result.
