摘要
介绍了寻点与追逐同步的矩形网格等值线追踪算法,是在传统的矩形网格等值线追踪算法基础上加以改进,通过设计等值线追踪的回追功能,使等值点生成与等值线追踪同步进行,在追逐等值线的过程中计算等值点.由于回追功能,无论非闭合等值线还是闭合等值线,都能够从区域内任一等值点开始,快速追踪出该等值线.
This paper has it is introduced that the contour tracing algorithm of rectangular grid with synchronization of point's generation and contour tracing. It improves the traditional rectangular grid contour track algorithm by the function of contour tracing back. And contour point generating and contour tracing can work at the same time. With the function, either a non-closed contour or a closed contour can be quickly traced out from every point on it.
