| 摘 要： | 提出了一种效率较高的等值线图扫描转换色彩填充算法。先求出扫描线与各等值线的交点．然后给出一系列判据确定各交点之间的颜色，利用OpenGL绘图功能实现等值线图的填充。该方法易于编程实现，适用于任何形状的等值线图，通用性强。

| Abstract: | An efficient algorithm of contour map color filling by scanning conversion is proposed.At first, got the cross points of a scan line and relative contour lines,then decided the colors of line segments among these cross points by a series of rules, finished the color filling of contour map using OpenGL graphical functions.Program implementation method of this algorithm was easy and suitable to fill any type of contour maps. |
