| 摘 要： | 随着三维数字城市建设的兴起和不断发展,3D GIS技术逐渐被人们所重视,多种三维建模软件也已被大量应用在三维数字城市的设计和创建中。首先通过与传统建模软件的对比,分析了Cityengine城市引擎软件在快速批量建模和与GIS软件数据交互方面的优点,同时也指出了Cityengine在建筑物室内场景方面缺乏对建模规则的研究。因此本文利用二维GIS几何数据作为模型的底面基础数据,借助Cityengine软件特有的CGA语法编写规则文件,对Cityengine平台下创建建筑物室内三维场景的方法进行了初步探究。通过对该方法的研究旨在使三维室内外场景形成良好的整体,弥补之前Cityengine只能对大场景进行外部批量建模而缺乏对内部模型研究的不足,扩展Cityengine在三维建模领域的应用范围,为智慧城市的创建设计以及可视化分析提供了新的手段。

| Abstract: | With the rise and development of three-dimensional digital city construction,3D GIS technology has been paid more attention by people,a variety of three-dimensional modeling software has been widely used in the design and construction of three-dimensional digital city.In this paper,firstly,by comparing with the traditional modeling software,it shows that Cityengine has advantage in the rapid batch modeling and GIS data exchange,and also has pointed out its lack of research on Cityengine modeling rules in indoor scene.This paper use the GIS two-dimensional geometric data as the basic data of a model,using Cityengine software's CGA grammar to compile the rules file,and has carried on the preliminary exploration on the Cityengine platform to create 3D building indoor scene.The research on this method aims at making the 3D indoor and outdoor scenes to form a good overall,making up the shortcoming that Cityengine can only do the external batch modeling for large scenes before,but lack of study of internal model,extended application range of Cityengine in 3D modeling field,provide a new means to create smart city and its visual analysis. |
