机群作战视景仿真系统的设计与实现

针对空间战场三维图像显示技术的需求,该文采用MultiGen Creator作为建模工具,Vega作为实时仿真驱动软件,在SGI图形工作站上开发了虚拟机群作战视景仿真系统,设计了系统软硬件体系结构,解决了地形分块、地形LOD（Level of Detail,层次细节）等大规模地形管理以及与飞行仿真系统的广播内存实时网络接口连接等技术,实现了空间战场环境、特效的逼真显示.仿真结果表明,该系统满足仿真实时性和逼真度指标要求,增加了飞行视景仿真的＂沉浸＂感.

Design and Realization of UAV Fleet Fighting Visual Simulation System

Aimed at the need of display technique of 3D image in the space battlefield,the paper adopted MultiGen Creator and Vega,developed UAV fleet fighting visual simulation system on the SGI graphics workstation,designed the architecture of hardware and software,solved the technique of mass terrain management such as terrain class,terrain LOD(Level of Detail),realized the IO in the real time network and the display of the space battlefield.The result of our research can meet the requirement of space battlefield visual simulation,and increase the immersion in the visual simulation.
