网络接口部件(NIU)中坐标转换算法的实现

The Research and Implementation of Coordinate Transformation in Network Interface Unit

为使NIU能提供把不同地域的仿真器联接到DIS中的能力 ,其主要功能之一就是坐标系统转换。本文介绍了DIS标准坐标系及其它几种相关坐标系 ,并在不同坐标系之间建立了坐标转换关系 ,讨论了不同坐标系中姿态的不同表示方法及其转换关系 ,同时在NIU中用C + +实现了所有算法。

One of the NIU's primary functions is coordinate system conversion in order to provides us the ability to connect different areas simulators to DIS. This paper introduces the standard of coordinates on DIS and the other relative coordinates , and establishes the coordinate transformation among the different coordinate systems . The orientation representations in different coordinate system and the orientation transformation are also discussed . At the same time, the algorithms have been realized with C++ in our NIU.
