摘　　要：针对现有电磁环境绘制研究中未考虑频段信息的情况,提出了一种多频段电磁环境绘制算法。基于光线投射算法实现,对传递函数进行了多频段设计,各频段颜色可以交互设置,同时定义了频段颜色增强因子,能够提高不同频段的颜色对比效果。最后,在统一计算设备架构下并行实现本算法,完成了实时交互的多频段电磁环境绘制。实验证明该算法能够方便、有效的展示电磁环境的频段信息,同时用户可以交互控制绘制及频段对比结果,便于观察和理解电磁环境。A multiband rendering algorithm for electromagnetic environment rendering is proposed,where-as previous work on electromagnetic environment rendering does not take into consideration.Based on ray-cast-ing algorithm,a multi-band transfer function is proposed in which colors used for band data are different and controllable.A color enhancement factor is defined to improve the contrasting effect of different bands in the fi-nal image.The proposed algorithm is implemented on GPU using compute unified device architecture,and is a-ble to render the electromagnetic environment at interactive frame rates.The experimental results show that the rendering results can clearly display bands information of electromagnetic environment.Furthermore,users can interactively control the rendering results for a better electromagnetic environment observation.
