基于Google SketchUp的虚拟城市三维景观构建技术研究

Research on modeling 3D landscape of virtual city based on Google SketchUp

虚拟城市是现代城市信息化发展的产物,越来越广泛地应用于城市规划、建设和管理之中。如何高效、快速地构建三维景观是建立虚拟城市的关键技术。基于Google SketchUp的虚拟城市三维景观构建方法,其操作简单,效率高,大大降低构建大规模三维景观所花费的时间和精力,从而可以降低工程的成本,加快城市三维景观技术的推广。这种方法可以广泛应用于各高校校园景观建设,住宅小区的整体效果三维演示,中小城市的三维景观建设以及各种城市规划工作中。

Virtual city is the production of information development of modem city. It is more and more widely applied for city＇s plan, construction and management. Reconstructing 3D landscape with high speed and efficiency becomes a key technology during the process modeling 3D landscape of virtual city based Google efficiency is high, greatly reduces the time and landscape SketchUp is the energy spends, thus may reduce the cost of the project, of building virtual city. The method of a new way, its operation simple, the which constructing the large-scale 3D speeds up the promotion of technology of modeling 3D landscape. This method may widely apply to various universities campus landscapeconstruction, the residential district overall effect 3D demonstration, 3D landscape construction of small city, as well as each kind of urban planning work.
