基于CAD和Creator的城市三维快速建模方法研究

提出一种城市三维快速建模方法,即利用现有城市基础地理信息资源,借助CAD和Creator软件平台,通过开发各种人机交互的辅助工具,结合特定的技术流程来实现既准确又美观的城市快速建模技术方法。文中以实际地块建模为例,详细描述了地块中建筑、地面、道路、小品等各类对象建模的具体建模方法,该方法既提高了城市三维建模的效率又保证了城市三维模型真实、美观的效果。

Research of City 3D Modeling Method Based on CAD and Creator

This paper presents a three-dimensional city modeling method, namely the use of the existing urban basic geographic information resources, with the help of CAD and Creator software platform, through the development of various auxiliary tool for human-computer interaction, combined with specific technical processes to achieve both accurate and beautiful city 3 d fast modeling techniques. An actual plot is used to modeling as an example, detailed describes the plot in the building, ground, road, and other kinds of objects modeling specific modeling method, This method can not only improve the efficiency of city 3 d modeling and 3 d model to ensure the city real and beautiful effect.
