海洋环境视景仿真方法研究

针对海洋工程领域仿真可视化的需求,系统研究了海洋环境的视景仿真方法。以三维图形高层开发环境——Vega软件为开发平台,基于honguet-Higgins海浪模型和纹理映射实现了动态海面仿真;基于“Environment Effect”仿真模块生成了海空效果,并设计运动路径,在场景中添加了飞翔的海鸟;利用三维建模、雾化、粒子系统等方法模拟了水下空间效果,利用Creator创建了海底地形模型,通过循环纹理映射实现了海底闪烁光斑的显示;对舰船尾流特效进行了仿真,并概述了各种海洋特效的仿真方法。应用于基于微机平台的虚拟海洋战场实时视景仿真软件中,生成的图像逼真,帧频高于30帧／秒。

Research on the Methods of Ocean Scene Simulation

For the requirements of simulation visualization in the field of ocean engineering, the methods of ocean scene simulation are studied synthetically. Based on high level 3D development environment -Vega,the dynamic offing is realized by using Longuet-Higgins wave model and texture mapping technology; based on the "Environment Effect" module, the sky is simulated, and some flying birds are added to the scene through designing moving path; using 3D modeling, fog function and particle system, the underwater scene is created; the flickering seabed terrain is modeled using Creator in addition to the circular texture mapping; the stern wake is simulated and the simulation methods of ocean special effects are summarized. The results show that the image is realistic and the frame rate is above 30 Hz.
