摘要
OpenSceneGraph(开放场景图,OSG)是当前流行的三维仿真引擎,具有开源可控的优点。利用OSG建立弹道导弹火力打击模型可为开展复杂导弹攻防体系仿真提供支撑。为此,提出一种以导弹发射点和打击点经纬坐标以及弹道高点高度为输入参数的弹道计算模型,并对其三维可视化方法中弹道曲线标绘、导弹尾焰与命中毁伤特效等关键技术进行了研究。仿真结果显示,与STK软件的计算结果相比,本模型的弹道计算误差较小,几乎可以忽略不计,同时可视化效果较为细腻逼真。
Open Scene Graph(OSG)is a current popular 3D simulation engine with open source controllable advantages.OSG is used to build a ballistic missile fire strike model,and to provide support for the simulation of complex attack and defense systems.A ballistic calculation model based on the latitude and longitude coordinates of the missile’s launching point and striking point and the height of the ballistic high point is proposed.The key techniques of ballistic curve plotting,missile tail flame and hit damage effects are studied in 3D visualization.The simulation results show that the error of ballistic calculation results between this model and STK software is almost negligible,and the visualization effects are quite delicate and realistic.
