摘　　要：针对现有震害模拟可视化方法建模环节存在的不足,设计一种基于SketchUp草图大师的区域建筑三维建模方法。该方法解决了传统建模方法中过于依赖原始数据和模型维护困难的问题,实现区域建筑建模的灵活性和模型的可维护性。利用OSG三维渲染引擎和Qt框架搭建震害模拟三维动态可视化平台,完成区域建筑震害模拟的三维动态可视化。以福建省福州市台江区某区域为例,对该区域进行三维建筑建模和震害模拟结果的动态可视化展示。结果表明:所提建模方法和平台具有可行性。A regional building three-dimensional(3D)modeling method based on SketchUp sketch master is designed to solve the shortcomings in the modeling segment of existing seismic damage simulation visualization methods.The method overcomes the problems of traditional modeling methods overdependent on original data and model maintenance difficulties,the flexibility of regional building modeling and the maintainability of the models are achieved.A 3D dynamic visualization platform for seismic damage simulation is constructed using OSG 3D rendering engines and Qt framework,the 3D dynamic visualization of regional building damage simulation is accomplished.Taking Taijiang District,Fuzhou City,Fujian Province as an example,3D building modeling and dynamic visualization displays of seismic damage outcomes are carried out.The results show that the modeling method and platform are feasible.
