摘　　要：三维可视化能够有效地描述和表达错综复杂的地下管网。目前地下管网三维可视化平台研发过程大多以Skyline为基础平台,存在成本高、管网加载和显示效率欠佳的问题。本文基于开源的三维图形渲染引擎OSG,设计并研发了管网信息可视化平台,有效节省了购买基础平台的成本。同时,该平台能够实现管网本体与多源地上数据的一体化三维高效展示,并具备丰富的专业管网分析功能,在地下管网三维可视化应用领域中具有显著的经济效益和实用推广价值。3D visualization can effectively describe and express intricate underground pipe networks. In view of the current threedimensional visualization of underground pipe network,the software platform research and development mostly base on Skyline platform,which is very expensive and inefficient on data loading and display. This paper designs and develops the pipe network visualization platform based on open source 3 D graphics rendering engine OSG,which not only can save the cost of purchasing the base platform effectively,but also can display the 3 D underground pipe network and multi-source data efficiently. The platform has abundant pipe network analysis functions as well.It will has significant economic benefits and practical promotion value in the field of 3 D visualization of underground pipe network.
