摘要
提出了一个从等高线地形图转换成三维真实感地形显示的快速算法，给出用深度标记法求出各点地形高度的插值算法，并对三维造型的快速显示作了探讨。实验证明本文造型方法速度快、精度高。
A fast algorithm is proposed which converts topographic map described by contour line into 3 D realistic topographic display. The interpolation algorithm for using depth labeling method to obtain the topographic height of every point in a region is given and fast display of 3 D modeling is discussed. Experiments show that the proposed topographic modeling is fast and accurate.
