摘要
三维建模技术不仅是数字城市建设的重要技术手段,也是三维城市GIS的核心。本文详细阐述了AnGeo软件中的三维建模及可视化技术,通过对获取的地图数据的预处理、地物建模和纹理处理、三维地形产生等操作实现了城市三维可视化,为城市的数字化建设提供了有效的参考。
The 3D modeling technique is not only an important technical means of constructing digital,but also the core of3 DCity GIS.This paper describes the research in the software called AnGeo on 3D modeling,by acquiring preprocessing map data,terrain modeling as well as texture detail and producing 3Dterrain and other aspects to achieve a 3Dmodeling and visualization of a city,which offers an effective reference for the construction of digital cities.
