摘要
对预制破片式战斗部导弹拦截飞行器目标过程的实时可视化仿真研究,并针对相关问题提出了解决方法。提出一种特性模型的概念,将目标几何信息和事实信息相关联,进而通过破片与目标的几何关系得到侵彻条件;利用射线算法对破片进行碰撞检测,并设计实现了模型的在线编辑方法。最后通过一个可视化示例校验了以上各方法的有效性。
Real-time visual simulation of the process of missile fragments damaging aircraft target is studied.In order to solve problems met while developing the simulation system,several methods are proposed.To solve the problem of how to get the physical information,such as material,of fragments and target from 3D visual models,a model called attribute model is proposed.Besides,the target mesh is modified and colored after fragments hit target,thus the authenticity in visualization is enhanced.An instance of damage assessment of fragmentary warhead attacks aircraft is also designed and implemented to verify methods proposed above.
