数字城市3维景观仿真技术探讨

Discussion on 3D Scene Imitation Simulation of Digital City

根据作者的具体实践指出了数字城市3维景观仿真具有信息交互性、分布性、实时浏览和景观再现以及景观真实性等功能特性,从数字城市3维景观仿真的数据获取、数据管理和数据处理以及地理实体到3维景观的转换等方面分析了实现数字城市3维景观仿真的技术思路,并对数字城市3维景观仿真建立工程中的一些关键技术,如景观背景变换、3维对象信息查询、天气效果的实现以及地形构建等进行了探讨。

This paper discusses the characters and the technology method of 3D scene imitation simulation of digital city. At the same time it also discusses some key techniques in construction engineering of 3D scene imitation simulation of digital city, such as scene background changing, informational inquiry of 3D scene objects, reality of atmospheric effects and construction of 3D terrain.
