三维图形的切割就是要把三维网格模型进行切割然后以等值线显示切面上的数值。运用适当的三维图形显示技术和可视化C++编成技术来实现的。(Three-dimensional graphics of the cut is to take three-dimensional grid model and then cut the contour values on the display section. Use of appropriate three-dimensional graphics display technology and visualization techniques to compiled C++ implementation.)
