摘要
以地形的等线图为原始信息,在一定简化条件下,经过数据处理,将每个地形元素的空间位置及灰度在计算机上显示,得到地形的三维图象.并能随着视点及视线的变化,实现地形图的动态三维显示.
Processing the base information of contonx map by simplify method,we can display both spacewise and grey scale of each of topographical elementon the computer monitor,and get the 3D sense of topography with the change ofview point and direction.
