【摘要】 本文对利用以规则格网表示的地面数字高程模型绘制透视立体图的方法进行了讨论,以透视原理为基础计算出模型点对应的变换点坐标。在分析过去采用的单方向处理隐藏线的方法基础上,提出了双方向处理隐藏线的方法,并应用该方法绘制出了透视立体图。更多还原

【Abstract】 This paper discusses a method of drawing perspective maps from DEM with regulargrids. The translated coordinates of model points are obtained according to the perspec-tive principles. The method of processing hidden lines in two directions is put for-word after analyzing the method of that in one direction and a perspective map is drawnby this method.更多还原
