| 摘 要： | 大规模城市三维建模一直是三维城市建设发展的关键,本文按照基础数据的分类方法,研究地理实体要素中各类模型构建规律,抽象出点、线、面状要素,利用符号匹配、规则构建及三角网构建方式进行批量建模。该方法实现了对地理实体要素三维表达的快速构建,具有较强的实用性。

| Abstract: | Three dimensional modeling of large scale city is always the key of three-dimensional city construction and development.According to the classification method of basic data,construction of laws of various models of geographical entity elements,abstract point,line,surface elements,using models matching,rule-made and triangulation method for batch modeling.This method achieve to construction of geographic entities three-dimensional expression,has a strong practicability. |
