摘要
阐述了电磁环境相关研究的迫切需求,阐述了开展电磁环境可视化研究的必要性和重要性。分析了电磁环境可视化的几种方法,并对直接体绘制、面绘制和切片法来实现电磁态势体数据的可视化进行了研究。在此基础上,开发了基于OpenGL的电磁态势3维可视化系统。该系统实现了电磁环境计算与可视化,表现了区域的地理环境、电磁场的分布等情况,为相关研究人员提供及时、全面、动态的电磁态势信息,为决策和控制提供依据和保障。
The pressing requirement for making research on electromagnetic environment was analyzed in this paper, the importance and necessity of studying on electromagnetic environmental visualization was also expatiated here. Then it made analysis on several methods for electromagnetic environmental visualization, furthermore studied on the visualization of realizing electromagnetic situation 3D datasets using direct volume rendering, surface fitting and slice rendering, and on the basis of it, a 3D visualization system for electromagnetic situation was devised. The electromagnetic environmental calculation and its visualization were realized in this system. The geographic environment and the electromagnetic field distribution which were shown in this system provided timely, and also provided a guarantee for battlefield decisions and controlments.
