| 摘 要： | 在现有二维数据的基础上进行快速的三维精细化建模是当前GIS领域的一个重要研究方向。本文给出了CityEngine参数化规则建模的流程和方法，解释了规则函数的原型及其作用，阐述了建筑物、道路、绿化和水体的三维精细化规则建模的具体步骤，并以山东科技大学校园三维为例，在CityEngine平台上构建了整个校园的三维场景。参数化建模能够通过参数更改模型的细节特征，实现了实时、动态的三维建模，弥补了传统建模方法的不足，对大规模城市快速精细化三维建模具有重要的指导意义。

| Abstract: | 3D fast fine modeling based on the existing 2D data is an important research direction in the current field of GIS.In this paper the procedures and methods of CityEngine parametric modeling by rules are presented,the rules function prototype and effects are introduced,and the procedures of 3D fine ruling modeling on buildings,roads,vegetation and water are elaborated.An entire 3D campus scene on CityEngine platform is built b taking the Shandong University of Science and Technology as example.Parametric modeling can change the specific features of modelsby adjusting the parameters,realize the real-time dynamic 3D modeling,and make up the shortcomings of traditional modeling methods.It is significant for 3D rapidly large-scale urban fine modeling. |
