引战配合仿真可视化过程中的碰撞检测技术

破片式战斗部主要依靠其释放的大量高速破片命中并毁伤目标,因此毁伤场中杀伤破片与目标间的命中统计是评估导弹毁伤效能的关键。从计算机图形学角度详细分析杀伤破片与目标交会的特点,在引战配合仿真可视化过程中综合利用了破片迹线模型、目标包围盒及空间剖分等有效措施,结合OpenGLPerformer在Vega平台下实现大规模杀伤破片与复杂目标间实时精确的碰撞检测,仿真结果表明碰撞检测技术在破片命中统计中的统计结果是真实可靠的。

Collision Detection in Visualization of Fuse and Warhead Coordination

Large scale of high speed fragments is the main element of the fragmentation warheads to destroy the targets.So it is extremely important to judge the hitting between fragments and the targets.Based on thorough analysis of the hitting characters between fragments and targets in accordance with the computer graphic viewpoint,this paper takes advantage of shot-line model,bounding box skill and space-separation skill to accomplish fast and high quality real-time collision detection between large amount of fragments and targets in the visual simulation of the coordinate of fuse and warhead used OpenGL Performer and Vega.The simulation result proves that it is practicable using collision detection skill to judge the hitting between fragments and targets.
