海战场态势实时三维显示系统研究与实现

针对当前舰载指挥控制系统只能基于二维图形、图标显示战场态势的问题，提出和开发了基于UDP的海战场态势实时三维显示系统，将虚拟现实技术应用到作战指挥控制系统中，用三维视景实时显示战场态势变化过程、战场态势发展以及双方兵力对抗过程。系统对战场实体位置进行了从经纬度坐标到直角坐标的转换，并为战场实体建立了简单的行为模型。为满足实时渲染和实时显示的需要，系统对模型、场景范围、显示方式等都做了优化处理，减少计算量，同时减少对硬件的依赖。

Research and realization of sea battle-field situations real-time display system

Today,the C~3I(Command,Control,Communications and Integration) System installed on warships can display sea battle-field situations only by 2D graphics and icons based on two dimensions.In this paper a real-time display system for sea battle-field situations was presented and developed,which introduced Virtual Reality technology into C~3I System,and used 3D scene to display changes and development of battle situations as well as force counterwork process of both sides.The system converted location of battle entity from longitude and latitude coordinates(geographical coordinates) to rectangular coordinates,and established simple action model for it.For real-time render and display,the system optimized model,scene scope and display fashion to decrease computing and the dependency on hardware.
