摘要
以吉林省汪清林业局金仓林场为研究区域，利用地形图丰富的高程信息，在Arc/info、R2V等软件的支撑下生成DEM数据，并以此为基础在面向对象软件Visual C++下利用OpenGL生成了林场的三维立体图形，并能用交互方式实现图形的旋转、缩放。
This paper selects Jingcang Forestry Center of Wangqing forest department in Jilin province as research region, Under the support of the soft Arc/Info , R2V, DEM was created based on the abundant altitude information of the relief map, then utilize these data, Three-Dimensional showing of forestry center was built under the help of Visual C++ and OpenGL, and can be rotated and scaled with interactive manner.
