摘要
本文提出一种基于格网的等值线的生成算法。根据边界线与非封闭等值线间的关系,建立等值线间的拓扑关系,并以树结构方式存储,从而实现数据的可视化。
This article studying the contour algorithm based on contour tracing for grid data, from the relationship between boundary lines and unclosed contours, the topologic structure among contours can be built and stored in a tree structure to realize data's visibility.
