In order to improve the training quality, three-dimensional simulation fighting view in wartime is implemented by Microsoft Visual Studio .NET2003 software and VR technology. Through the VR engine system, many functions such as mission edit and mission layout of unit battle, three-dimensional simulation fighting drilling can be come out, and presents some key technologies: state control technology, visual demonstration technology, campaign efficiency of unit battle. The result demonstrates that the system can fulfill the requirement of real time and some battle functions as mission layout, real time scout, emulating simulation. The result reflects good impression in the reality degree and mutuality.
