利用VC++编程实现样条曲线的绘制实例，源代码编译于VC++6.0，通过测试发现本示例程序距真正的“手绘”曲线还有一段距离，甚至说它是全自动的，也就是选择生成选项后，程序是自动生成的曲线，可以对生成的曲线进行位置移动，倍数放大等，但不能用鼠标手动去改变它们的形态，源代码收集于国外，仅供学习参考。(Using VC++ Programming-spline curve drawing examples, source code in VC++6.0, to pass the test procedures found in this example from the real " hand-painted" curve is still some time before, or even that it is fully automated, is the choice of generation options, the process is auto-generated curve, the curve can be generated for the location of the mobile, such as a multiple of amplification, but not manually with the mouse to change their form, source code are collected in foreign countries, only to learn the reference .)
