保持颜色一致性的动态电磁环境绘制算法

针对电磁环境绘制的研究现状，提出了保持颜色一致性的动态电磁环境绘制算法。明确了绘制中的颜色一致性原则：同一数据值对应同一颜色，绘制图像序列中颜色变化与数据变化保持一致。在颜色一致性分析的基础上，对静态电磁环境的绘制方法进行了修改，使其能够在绘制动态电磁环境时保持颜色的一致性。必要时，颜色与数据值的对应关系可以交互调整或自动调整，以适应数据场的值域变化。实验表明，算法能够在保持颜色一致性的情况下绘制动态电磁环境，直观显示其变化情况，便于用户观察和理解。同时算法可并行执行，在统一计算设备架构下具有较高的执行效率，利于算法的使用。

Rendering algorithm with color coherence for dynamic electromagnetic environment

After studying the existing state of the art, we firstly propose an rendering algorithm with color coherence for dynamic electromagnetic environment. The definition of color coherence for rendering is that the same value in different data frames corresponds to the same color and the change of colors in different rendered images follows the changing data. Based on the definition, the algorithm of rendering static electromagnetic environment is improved to render dynamic electromagnetic environment with color coherence kept. If needed, the relationship between mapping data and colors is edited by user interaction or the principles defined for the algorithm to follow the change of data. The experimental results show that the dynamic electromagnetic environment can be rendered with color coherence kept by the algorithm and the change of data is shown in the rendering images, which is helpful for user to understand the electromagnetic environment. Furthermore, parallel implementation of the algorithm using compute unified device architecture gets a high efficiency, which is good for using it.
