摘　　要：为了模拟大规模动态水面场景,首先采用控制参数叠加来实现水域表面的流动性,其次使用Gerstner波叠加来实现水域表面波峰和波谷的不规则性.利用视野范围的特点,对不同视点的水域表面细节数据进行分析,采用基于视点的LOD技术绘制场景网格.针对动态水域引起的波形与网格的"裂痕"问题,采用权值叠加法,实现场景构建的实时性.利用GPU矩阵式并行计算特点,将场景构建的功能移植到GPU中进行计算,提高绘制效率.In order to simulate realistic the large-scale water scene with dynamic, firstly the flow water surface was achieved using the superposition of controlling parameter. In order to realize the craggedness of wave crest and the gentle of water trough, the superposition of Gerstner wave is used to achieve the irregular surface of the water. The details of data for water scene is analyzed by the LOD technology based on render scenes grid using the characteristics of view field. The construction of real scene is realized. The problem of caused by fluctuated water the waveform and grid is the crack problem. The method to solve is the weight su- perposition. Using the calculation of GPU matrix parallel, the construction of scene features is explants into GPU to improve rendering efficiency.
