Contour 等值线搜索和显示算法。VC++编成，使用OpenGL等-Contour contour algorithm to search and display. VC organization, such as the use of OpenGL

基于VC+OPENGL,关于cassini椭圆函数的等值线生成,涉及等值线插值问题.-OpenGL-based VC, cassini elliptic function of the contour generation, isogram involving interpolation.

该程序是Cassini椭圆函数的等高线曲线，再VC++MFC环境下用OpenGL绘制，本程序采用的方法是利用插值法求得等高曲线和单元边线的交点，函数在50*50的单元栅格上采样。,The program is Cassini cnoidal contour curves, and then VC++ MFC with OpenGL rendering environment, the procedure adopted is to use obtained by interpolation co

在Visual C++中采用网格序列法实现等值线生成,为MFC 可执行文件；-In VC sequences using a grid method to achieve contour generation
