利用Google SketchUp快速构建滑坡三维模型

Google SketchUp是直接面向设计创作过程的三维建模软件,功能强大,简单易用,并且可以与Google Earth结合应用。三维建模一直是滑坡灾害研究中的热点,本文首先介绍了利用SketchUp进行滑坡三维模型的构建思路;然后重点阐述了构建流程,包括滑坡表面地形的获取、滑动曲面的构建、滑坡三维体的生成以及三维模型的渲染;最后通过一个具体实例展示了用SketchUp构建的具真实感的滑坡三维模型、三维剖面以及将模型放置到Google Earth中等应用。结论表明使用SketchUp是进行滑坡三维建模的一种理想方法。

Rapid Construction of Three Dimensional Model of Landslide Using Google SketchUp

Google SketchUp is a kind of 3D modeling software which directly faces the creative design process,with the advantages of strong function and easy-to-use,and can be combined with Google Earth. 3D modeling is always the hotspot in landslide disaster research. This paper firstly introduces the train of thought about 3D modeling of landslide using SketchUp; and then puts its focus on 3D modeling processes which include getting topography surface of slide,constructing sliding surface,building 3D body of landslide,and rendering 3D model; at last,an example is given to show some applications about realistic 3D model of landslide,3D profile and to put 3D model to Google Earth. The conclusion shows that constructing 3D modeling of landslide using SketchUp is an ideal method.
