大规模海浪交互模拟

提出了一种仿真拥有交互物体的大规模海洋场景的有效方法。首先采用复合动态网格来仿真海面网格；其次，采用基于频谱统计的FFT算法对非交互波浪进行仿真，求得非交互波浪的高度场；接着，以船行波为例，重点分析了交互波产生的位置和时机，通过引入仿真引擎和求解二维波动方程来实现对交互波的仿真，求得交互波的高度场。最后对两种波的高度场进行叠加，从而实现对海洋场景的整体仿真。实验结果表明，能在保证实时绘制的前提下达到较好的真实感，适用于拥有交互物体的大规模海洋场景的仿真。

Simulation of the Large-scale Ocean Scenes with Interacting Objects

This paper presents an effective method to simulate the large-scale ocean scenes with interacting objects.Firstly,multiple moving grids was used to simulate the ocean surface grid.Secondly,FFT algorithm based on statistical measurements of frequency spectrum was used to simulate non-interactive wave and obtain its height field.Thirdly,as for the boat wave,an emphasis on the analysis of the creating position and occasion of the interactive wave were given,realizes the simulation of interactive wave and obtai...
