在分析现有三维空间对象的几何表示方法和面向对象方法的基础上，从三维空间的角度去理解和表达现实世界中的地物、地理现象及其空间关系。提出一种基于面向对象和VRML的地理实体三维建模方法，以三维建筑物模型构建为例的验证结果显示，该方法可以快速的进行三维重建，为不规则、非对称性地理实体三维建模及地理实体的面向对象三维可视化的实现提供了新方法和新思路。

Based on analyzing the geometric representation method of the existing 3D spatial objects and object -ori-ented method ,this paper aim to understand and express the objects ,geographic phenomena and their spatial relationships in the real world from the 3D space perspective ,and present a object-oriented-based and VRML 3D modeling method for geographical entity.By taking the 3D building modeling as a example ,the results suggests that the method can complete the 3D reconstruction quickly ,and provide a new method and new thinking to construct the 3D model and realize the ob-ject-oriented 3 D visualization for irregular and asymmetric geographic entity .
