摘要
使用B样条基函数给出NURBS曲线的参数定义式,提出一种确定节点序列{ti}n+ki=0的实用方法.详细地讨论了权因子在NURBS曲线造型上的微调作用以及在实际问题中的应用.
Apply B spline basic function to give parametric formula of NURBS curve, raise a practical method of determing knot array. It discusses carefully the trimming affect of weighted factor in NURBS curve's designing, and introduces the application in practial problem.
