基于CityGML的城市建筑物三维建模研究

The Research of 3D Urban Buildings Modeling Based on CityGML

城市建筑物三维建模是虚拟3D城市建模的基础和重要组成部分。本文对基于CityGML1.0(City Geography Markup Language 1.0,城市地理标记语言)的城市建筑物三维建模技术进行了深入的研究,主要内容包含了CityGML1.0的简介、城市建筑物三维建模的方法和内容等,并给出了一个实际建模的例子,最后对CityGML在城市建筑物三维建模上的应用和发展进行了预测。

3D urban buildings modeling is the foundation and important part of virtual 3D city modeling.This paper deeply researches the technology of 3D buildings modeling which based on CityGML1.0（City Geography Markup Language 1.0）,It mainly contains introduce of CutyGML1.0,the methods and content of 3D urban buildings modeling methods and etc.It also gives an actual modeling example.Finally this paper forecasts the application and the development of CityGML in 3D urban buildings modeling.
