该资源包括两个压缩文件，一个是由mfc生成dialog，然后通过鼠标拾取样条曲线的编辑点，该例程从网上下载的，在此对原作者表示感谢；还有一个是根据上面的例子，由事先确定的点，计算出插值点，通过opengl绘图，显示插值效果，例子比较简单，有很多函数未用到，没有加限制条件，改变控制点时，不能超过（0，0），（2，2）。-The resources include two compressed files, a dialog is generated by the mfc spline curve editing point and then picked up by the mouse, the routine is downloaded from the Internet, thanks to the author of the original work in this　there is a based on the above example , can not exceed, by a pre-determined point, the calculated interpolation point, the OpenGL graphics display interpolation effect, the relatively simple example, there are many functions not used, there is no restriction conditions, to change the control point (0,0), ( 2,2).
