摘　　要：通过等值线的绘制与填充过程分离的编程思想,先用OpenGL硬件加速的光栅化技术实现区域快速填充,然后利用MFC下的GDI绘图功能在相同的区域上绘制等值线。该方法不涉及到复杂的算法,用很简单的代码就能实现与商业软件视觉效果相媲美的等值线填充效果,且适用于离散区域为任意形状的多边形网格系统。This paper presents a programming idea of drawing and filling contours respectively. First the zone is filled by ta￣king advantage of rapid raster display of OpenGL, then on the same zone contourlines are generated by using GDI functions of MFC. Without any complicated algorithm, the program is easily realized, but provides excellent visual effects comparable with commercial software. In addition, the method can be applied to various grid systems.
