摘　　要：主要介绍了地形从模型到可视化对象生成的原理和基本步骤,利用这些原理、步骤,可以不借助任何基础引擎实现地形的可视化,为3D开发者提高地形可视化技术和应用能力,提供了一定的理论和经验基础。In this paper, the principles and basic approaches to building the visualization objects from models of the terrain are introduced. With them, the visualization of terrain can be realized depending on no basic engine,which establishes the theory and experience foundation for 3D developers in the fields of improving their technique and application abilities to realize the terrain visualization.
