多机协同的分布式海上攻防视景仿真

Collaborative distributed ocean attack-defense scene simulation

基于高层体系结构,构建了在分布式网络环境下多机协同的海上攻防对抗仿真系统.根据舰载反舰导弹的攻防过程设计仿真模型.为逼真描述作战环境和态势进行视景仿真,采用改进的快速傅里叶变换算法进行海浪建模;利用粒子系统的基本原理,结合OpenGL的纹理映射技术,实现动态爆炸模拟.根据仿真模型设计各联邦成员,将三维视景仿真作为联邦成员加入仿真系统的联邦执行以实现多机协同渲染,从而大幅度提高了显示帧率,并使视景仿真可灵活扩展.

A simulation system of ocean attack-defense under distributed network environment was established via the high level architecture, whose model was designed according to the ship-based missile attack-defense process. Visual simulation was developed in order to demonstrate a real battlefield scene. The fastest fast Fourier transform in the west was utilized to simulate large-scale ocean water. Based on principles of particle system, dynamic explosion were simulated combined with texture map- ping technology of OpenGL. Federates were designed according to the simulation model. 3D visualization federate was designed to join the federation of system to cooperate rendering among PCs. Therefore the frames displayed per second be greatly improved and visual simulation extended flexibly.
