| 摘 要： | 本文对由规则格网数字高程模型生成带灰度的格网面片透视图的方法进行了研究，并实现了这种透视图的自动生成。提供了交互功能，可随意改变观察位置、方向，光线照明方向，投影比例尺和高差夸大系统。此外，还对生成高度真实感地形透视图提出了建议。

| Abstract: | A automatic plotting method of intensity-shaded terrain porspoctive graphy is studied. An experiment is performed by this method,which has an interactive function,and the view position, view direction,lumination direction of light,projection scale and zoom coefficient of the difference of elevation can be changed as one pleases.Besides,the authors make a suggestion on how the automatic plotting of terrain perspective graphy with high level of reality can be realized. |
