该程序利用vc++实现了曲线的绘制，实现功能如下：画圆，画金刚石模型，Bezier曲线的绘制，B样条曲线的绘制，手绘beizer和B样条曲线-Use of the program vc++ Achieved Curve to achieve the following functions: drawcircle, painting diamond model, Bezier Curve, B-spline curve drawing, hand-painted beizer and B-spli

绘制Bezier曲线,通过人际交互的方式获取控制点，然后生成Bezier线-draw Bezier curve
