三维地形表面的可视化实现

Visualization of 3-D Terrain Surface

三维地形的可视化研究是当前对港口、航道等进行地形演变、泥沙淤积等分析研究的前沿课题 ,是快速、及时地再现地形三维信息及综合分析的有效途径。文中介绍了如何通过微软VB开发平台实现地形表面的三维可视化 ,并实现三维图形的缩放、旋转与输出。

Study on visualization of 3 D terrain surface is the leading subject in the analysis of fluvial process and sedimentation of harbors and waterways.It is an effective way to reproduce 3 D terrain information fast and promptly and to make comprehensive analysis.It's introduced how to use Microsoft VB developing platform to realize the visualization of 3 D terrain surface and to realize the zoom,rotation and output of the graphics.
