等值线抽取中交点连线二义性问题的研究

科学计算可视化是一门新兴的学科，网格序列法是其中二维标量场上学值线抽取的一种主要方法，如何解决交点连线的二义性问题是该方法的一个关键性问题本文提出了解决该问题的一个新方法，它克服了现有方法中所存在的缺点，在不增加采样点的前提下，较好地解决了二义性问题。

Research on the Problem of Duality in Intersection Linking in Contouring Methods

Visualization in scientific computing is a new branch of computer science. The grid sequence method is one of the major methods used to take out contour lines from two dimensional scalar field. The key problem to this method is the duality in intersection linking. This paper presents a new technique which has overcome the shortcomings of the two existing methods. This technique solves the problem better with no need of more sampling data.
