从用c语言编出程序要用文件输入数据。 绘制二次B样条曲线的表达式： P(0,2)(t)=P0*G(0,2)(t)+P1*G(1,2)(t)+P2*G(2,2)(t) 0<=t<=1-from using language out to document procedures with the input data. Drawing II B-spline curves of expression : P (0,2) (t) = P0 * G (0,2) (t) * G P1 (1,2

mfc编写的画图小程序，可以画出来曲线，贝塞尔和b样条(MFC prepared drawing applet, you can draw out the circle)
