摘要
三维城市模型作为城市三维地理信息系统的重要组成部分,已广泛应用于城市规划、城市建设、建筑设计等领域。随着计算机图形学技术以及虚拟现实技术的不断发展,为快速、自动化生成高精度的三维城市模型提供了条件。本文基于OGRE引擎,阐述了三维城市建模技术的整体架构及关键技术,开发了自动化建模工具及三维可视化平台,实现了城市建筑自动建模及模型实时渲染显示。
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.
