摘　　要：为了解决城市景观风貌设计中,二维CAD效果图难以反映三维景观的真实感,且简单的三维可视化不能满足设计人员对景观的空间分析需求,设计并开发了一个城市三维景观漫游系统。系统设计中,首先利用Google Sketchup对常用的景观模型建模并搭建三维模型库,然后开发一系统,自动调用模型库中的模型生成三维场景,并进行景观设计。系统具有通用性和适用性,可为城市规划相关部门在城市景观研究、设计、管理等方面提供具有真实感和空间参考的决策支持信息。In the design of urban landscape,it＇s difficult to use two dimensional CAD renderings 3D landscape reflecting the realistic,and simple three- dimensional visualization cannot meet the designers＇ needs in the space analysis. In order to solve these problems,a 3D urban landscape roam system was designed and developed. The urban 3D landscape roam system can meet the demand of design of landscape spatial analysis. In designing this system,firstly,use Google Sketchup to model for common landscapes and build a three- dimensional model base,then develop a system that automatically call models to generate a three- dimensional scene,and conduct the landscape design in the end. This system is generic and applicable for the urban planning departments,which can provide a realistic and spatial reference and decision support information in the area of city landscape research,design,management and so on.
