The Visualization Toolkit (VTK) is an open-source, freely available software system for 3D computer graphics, image processing, and visualization. It consists of a C++ class library and several interpreted interface layers including Tcl/Tk, Java, and

最基本的3维8节点线性有限元程序，读取ANSYS的cdb文件，输出采用Paraview的vtk文件。 可以输出节点位移和应力云图。(Basic linear 3D 8 nodes brick finite element code. Use ANSYS cdb file for input and Paraview vtk file for output. Displacement and Stress contour is available.)

这是一个基于QT和VTK开发的一个三维可视化界面，可以用面绘制实现序列DICOM的三维重建。(This is a 3D visualization interface based on QT and VTK, which can be used to realize 3D reconstruction of sequence DICOM.)
