等值线是一种离散数据的图形表示方法，在水利、土木、地质、石油勘探等工程和技术领域内广泛的应用。常规的等值线绘制通常采用网格法，其绘制的步骤一般为：离散数据网 格化；等值点的计算；等值线的追踪；光滑和标记等值线等。等值线图的显示方式一般有两种：(1)等值线显示，即采用线条上加注数值标记的方式显示数据，这种方式的特点是简捷；(2)采用彩色填充的方法来显示数据，既用不同的颜色来显示不同的数据，这种方法的特点是比较直观。两种方法的计算机实现也各不相同，一般来说，它们都需要将数据进行要用 到的网格网格化。第一种方法必须进行等值线的追踪、光滑和标记等值线。而第二种方法可以在追踪出等值线的基础上进行，也可以不做等值线的追踪直接在网格数据上进行操作。 方法实现的难易程度各不相同

  • yjyj8181 :
    用这个画了个地下水的等值线图.还不错,就是有几个小bug,一在匹配节点的时候没有做微量偏差,二在填充颜色的时候有个判断有问题,导致填充不完整.如有需要修改后源代码的同学,可以发邮件到27148861@
