Research and realization of sea battle-field situations real-time display system
海战场态势实时三维显示系统研究与实现

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.
