摘    要:一般的等值线图形采用函数值跟踪算法,该法对内部封闭等值线的起点确定比较麻烦。笔者采用面向对象的程序设计方法给出适用于任意形状单元的等值线图的通用扫描线生成方法,采用VC6.0中的MFC实现了三点三角形、六点三角形、四点四边形、八点四边形和九点四边形的计算结果图形显示。并给出了算例。

关 键 词:面向对象  计算机图形学  等值线图  数据可视化  扫描线法

Abstract:The tracing method is applied to generate the contour graph, it is difficult to find the start point of the interior closed contour beam. This paper presents a general scanning beam method which can be applied to generate color contour graph for elements with arbitrary shape by the object-oriented programming. We give visualization of the elements of triangle the element with 3 Points, triangle element with 6 Points, quadrilateral element with 4 Points, quadrilateral element with 8 Points, quadrilateral Element with 9 Points and the example by the MFC of Visual C++ R6.
Keywords:object  oriented  computer graphics  color contour graph  visualization
