SketchUp在虚拟小区规划中的应用研究

The Research on the Application of SketchUp in Virtual Community Planning

摘要: 针对由于构建城市三维模型工作量巨大、费用昂贵、须具备较高的制作技巧，虚拟现实技术无法广泛应用的城市规划的现状，本文以SketchUp为平台，以规划设计的总平面图、立面剖面图和方案效果图为基础数据，研究如何快速、高效、低成本的制作出浸沉感好、交互性强和构想性优越的三维场景。本文采用了SketchUp基于CAD底图和效果图两种建模方法，并通过丰富景观模型、三维模型“瘦身”和设置光影效果三种手段进一步优化三维场景，提出利用Google Earth平台调整规划方案的设想。该研究充分显示了SketchUp结合虚拟现实技术应用于城市规划的优越性。

Abstract: Because of the huge workload, high fee and complex production skills on the establishment of 3D urban model, Virtual Reality technology cannot be applied widely in urban planning. To face this problem, this paper focuses on how to create good sense, strong interactivity and superior im-mersion 3D scenes more efficiently and with lower cost. This paper adapts two modeling methods of SketchUp based on CAD map and effectiveness, through three means of enriching the landscape model, downsizing the 3D model, and setting light effect to further optimize the 3D scene; this pa-per also puts forward a suggestion that takes advantage of Google Earth to adjust the planning project. This study shows the advantages of Virtual Reality combining SketchUp in urban planning application.
