广州市“数字绿化”仿真应用的城市园林景观3维可视化技术研究

摘要

广州市大力开展“数字绿化”管理平台建设,依托其中的广州市林业和园林局3维实景展示项目,以仿真应用为目的,研究基于CAD设计施工图和普查获取的城市园林景观GIS数据的3维可视化技术,具体叙述了相关的技术方法和流程.%" Digital Greening" management platform is under development in Guangzhou city. Relying on the background of 3D virtual exhibition projects of Guangzhou Administration of Forestry and Gardening, and the purpose of simulation applications, this paper studies on the 3D visualization technology of urban landscape based on detailed engineering CAD drawings and census survey GIS da ta, especially explains in details the corresponding 3D visualization methodology and processes.
