摘　　要：三维虚拟校园是校园信息化重要组成部分。目前,国、内外基于GIS的三维虚拟校园构建方法都存在周期长、成本高、不可重用等缺点,本文提出了一种基于CityEngine规则的三维虚拟校园构建方法。具体步骤包括:(1)三维虚拟校园场景构建;(2)基于CityEngine平台,利用GIS矢量数据,通过建立CGA规则构建校园建筑物、道路和其他附属设施三维模型。基于CityEngine规则的三维虚拟校园构建,能充分利用现有GIS数据,快速和批量构建三维模型,提高三维虚拟校园的效率和节约建设成本。Three dimensional virtual campus is an important part of campus information. At present, there are many disadvantages such as long period, high cost and non reusable in the construction of 3D Virtual Campus Based on GIS. In this paper, a method of constructing 3D Virtual Campus Based on CityEngine rules is pro- posed. Specific Steps include： （1） Construction of 3D virtual campus scene; （2） Based on CityEngine plat- form, using GIS vector data, through the establishment of CGA rules to build campus buildings, roads and other ancillary facilities three - dimensional model. The construction of 3D Virtual Campus Based on CityEngine rules can make full use of the existing GIS data, construct 3D models quickly and in batches, and improve the efficien- cy and cost of construction.
