| 摘 要： | 针对钢结构桥梁的三维可视化问题,提出利用VTK的三维建模功能,同时利用C#语言实现了钢结构桥梁的节点单元数据的三维可视化。研究VTK的数据表达方式,实现模型的拉伸、旋转等建模;结合四元数法,实现模型的旋转几何变换。实验结果表明,通过VTK实现钢结构桥梁节点单元数据三维建模是可行的;该可视化平台具有很好的可移植性和扩展性,并且可以方便的依靠底层数据对模型进行有限元分析等开发工作。

| Abstract: | A 3-D modeling method, taken advantage of VTK, combined with C#, was proposed to solve the 3-D visualizing problem of steel structure bridges. Data expression of VTK was researched, geometric transformations of model such as stretching, rotation were implemented through VTK and quaternion algorithm. Experiment showed it was practical to implement 3-D model building via VTK. In addition, the visualization platform was with portability and expansibility, finite analysis for model was available with underlying data. |
