摘　　要：给出了一种在虚拟海战场景中的快速高效的海浪建模算法 ,该算法考虑了海浪的波级 ,引入了概率统计思想 ,并采用视点相关的海浪三角形网格来表示海浪模型 ,该算法支持虚拟海战场景中的实时漫游 ,不依赖于特定平台的恒定帧速的动态显示以及图像质量和几何面片数量的折衷 .应用证明算法很好地满足了虚拟海战场景的需要 .An efficient and fast ocean wave modeling algorithm has been proposed for virtual naval battlefield walkthrough. The algorithm considers the complex ocean wave conditions, introduces probability statistics and using view dependent continuous resolution triangle meshes for ocean wave presentation. we have integrated the algorithm in a virtual naval battlefield walkthrough that supports real time dynamics display at a constant frame rate independent of machine characteristics, and the tradeoff between the amount of detail in geometry and color. The algorithm has been improved to meet the requirement of virtual naval battlefield walkthrough very well.
