Three-Dimensional Dynamic Visualization of Regional Building Seismic Damage Simulation Base on SketchUp and OSG
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 simu-lation 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.
