查询词典 vector analysis

The results are displayed vividly in virtual scene which is established with program language of Visual C++ and OpenGL. At present flow field simulation manner mostly has time delay, deficient controllability, so this paper brings forward the methods of drawing flow velocity vector graphics with OpenGL in the 3D virtual scene to simulate and analyze flow field. At the same time cross section and flood analysis are completed. Accordingly, it assists flood flow field visualization and provides the more effective analysis method for the flood mathematics model research and application.
