摘　　要：虚拟海战场仿真中,大规模动态海面的实时生成、各种作战平台的模拟是关键问题。基于海浪统计学模型,采用快速傅立叶逆变换、层次细节技术和与视点相关的可见性预判断技术,实时生成动态海面,依据蒲氏风级与浪高的对应关系,模拟不同等级海浪;采用3DM AX建模软件实现了舰艇、潜艇、飞机、导弹等作战平台的仿真;最后,采用粒子系统实现自然环境中的雾、雨、雪,以及舰船、飞机、导弹的尾迹的仿真。视觉效果较好。Real-time and visibility rendering of large scale ocean,emulate every combat platform are key questions in Virtual battlefield simulation.Based on statistical wave models,this paper firstly realized a real-time rendering algorithm of ocean surface by used technologies of inverse Fast Fourier Transformation(FFT),Lever Of Detail(LOD) and view-dependence visibility estimation and also classified ocean wave according to the correlation of wind and wave height.Use 3DMAX to realize the emulation of naval ships,submarine,plane,missile and so on.At last,realize the simulation of fog,rain,snow,and wake of ship,plane,missile with particle system.The visibility is well.
