地形可视化仿真建模技术研究与实现

Research and Realization of Simulation Modeling Technology in Terrain Visualization

在地理信息的三维可视化的研究中,TIN是构建DEM最常用的方法,为了使生成的TIN模型更具有真实感,提出了基于VB与DirectX表面绘制的方法,并通过实例验证了该方法的可行性。

TIN is a general way for building DEM in research of 3D geographical information visualization. In order to make TIN model closer to reality, this paper puts forward a surficial drawing approach based on VB and DirectX. At last it is tested, and it is productive.
