虚拟现实环境中运动复杂目标的图形电磁计算

Graphic electromagnetic computing for moving complex targets in virtual reality environments

利用NURBS曲面对虚拟现实环境中的目标进行几何建模。通过对入射场进行Lorentz变换 ,得到运动坐标系下的入射场 ,进而求得运动坐标系下的散射场。对运动坐标系下散射场再进行Lorentz反变换 ,就可得到静止坐标系下散射场。

Objects in virtual reality environments are modeled in geometry by NURBS curves.Firstly, through lorents transfer incident field is changed in locomotive coordinates, then scattering field in locomotive coordiantes can be gotten. Secondly, through lorents inverse transfer scattering field in locomotive coordinates is changed into the scattering field in stationary coordinates.Finally, the RCS of the locomotive object can be received.
