基于MT方法的水声波束三维可视化实现

以往水声波束的可视化描述大多基于二维平面显示,不能很好地表达水声波束在水下空间的形态及其动态效果。为使水声波束能够以三维可视化的形式表现,提出了一种基于数据场绘制等值面Marching Tetrahedral法的水声波束三维可视化实现方法。以水声波束方程为基础,绘制出水声波束在水下空间的形态、单波束扫描以及多波束搜索效果,并通过对细分空间的优化处理,保证了三维可视化水声波束在视景仿真中的实时性。三维可视化效果表明,生成的三维水声波束显示效果逼真、流畅,能够提供更加直观生动的画面。

Abstract：

In order to reflect more vivid details of attack and defense of surface warfare scene simulation such as missile launch, missile hit, gun fire, radar search and decoy expand, several key technologies including system designing, component-based modeling, component-based model-driven were researched. A component-based modeling method was proposed which combined multi-granularity modeling and sub-model replace. This method could load component-based model dynamically by list configuring and memory mapping. The component-based surface warfare scene simulation system designed as a federate of a large distributed surface warfare simulation system federation could receive data of the corresponding federate such as missile, artillery, radar and jamming system, and then the component-based model in the 3D scene was driven.

Abstract：

In order to control the form of multi-fighters cooperative combat in formation, the military notion model was introduced. Several typical tree form team models （triangle, lozenge and leader-follower） based on geometry constraint were proposed on multi-fighters flying in formation. Through researching VR technology, a visual simulation testing model platform was built for making a plan of flight-testing mission. The simulation results indicate that the arithmetic can be well used on simulating flight, anti-tactics and valuating the flight models.
