| 摘 要： | 给出一种面向对象的建筑物建模方法.该方法使用单纯分子地物模型对建筑物进行描述,建模时将建筑模型分解为若干形状简单的分子地物,通过树结构和双向循环链表的形式对其进行整合,简化了数据表示,便于以建筑物为单元进行操作.且在不同对象间引入结合度概念,探讨了不同分辨率查询问题.

| Abstract: | An object-oriented building modeling method is presented, in which 3D buildings are described by several simple molecule objects. These molecule objects can be integrated through the use of tree structure and circle chain tables so as to simplify the data structrue. In addition, a concept of integrating order is introduced to effectively solve the problem of queries with different resolutions. |
