带有颜色填充的等值线画法研究

摘要

Based on the analysis of some common contour rendering algorithms and some experiences, a new model for rendering a color-filled contour map with scattered data is developed. It is simple, effective, more precise, more flexible and can fill the map with color easily to make the map express more. All the details are provided in the article.%本文分析了常规的等值线绘制算法的缺点,根据经验提出了一种由离散数据生成等值线的算法,不但简单有效,又能达到更好的精度,而且适应能力更强,并且能方便地实现颜色填充,丰富了等值线图的表达能力.文中给出了具体算法的实现原理和过程.
