MFC程序包含绘制直线、圆、Bezier曲线、B样条曲线四种绘制类型，能够动态修改曲线控制顶点，从而改变曲线形状。能够绘制相应的伯恩斯坦基函数图象。-The MFC program includes draw straight lines, circles, Bezier curves, B-spline curve four draw type, able to dynamically modify the curve control points, thus changing the sha

Bezier曲线和B样条（BSpline）曲线绘制，用VC++自带API函数实现-Bezier curves and B-spline (BSpline) curve drawing, API function comes with VC++
