Abstract: As an important part of 3D GIS, 3D city model has been widely used in urban planning, urban construction, architectural design and other fields. With the development of computer graphics technology and virtual reality technology, it provides the conditions for fast and automatic generation of high precision 3D city model. This paper is based on the OGRE engine, describes the overall architecture and key technology of 3D city modeling technology, developed the automatic modeling tools and 3D visualization platform, 3D City Modeling and automatic 3D city model real-time rendering display.

Key words: 3D city modeling, automatic modeling, OGRE, 3D visualization
