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 research on the target process of the pre-made fragment warhead missile interceptor vehicle is proposed, and the solution to the related problems is proposed. A concept of characteristic model is proposed, which associates the target geometric information with the factual information, and then obtains the penetration conditions through the geometric relationship between the fragments and the target. The ray algorithm is used to detect the fragments and the online editing method is designed and implemented. Finally, a visual example verifies the validity of the above methods.
