利用de Boor算法绘制B样条曲线
运用计算机图形学的知识,采用4阶B样条基函数,节点向量取为[0,0,0,0,1/4,2/4,3/4,1,1,1,1]
先绘制控制多边形,再用分段直线段绘制B样条曲线(Using the knowledge of computer graphics, the 4 order B spline basis function is used, and the node vector is taken as [0,0,0,0,1/4,2/4,3/4,1,1,1,1].
First, draw the control polygon and draw the B spline curve by piecewise straight line segments.)
