摘要 非均匀有理B样条曲线(NURBS)是一种优秀的插值方法,通过研究NURBS曲线导数形式,并将其导数信息转化为NURBS曲线的控制点信息,从而对曲线插补过程进一步控制。最后使用VC++和MATLAB进行新型算法的开发,仿真的结果表明,加入导数信息的NURBS算法得到的曲线总体上更加协调,可以更容易把握曲线的设计。 NURBS is an excellent method of interpolation.To better take charge of the interpolation,we integrated the information of the derivative into the control points,by studying the derivatives of the NURBS curve.We used VC++and MATLAB to develop the new algorithm.The simulation proves the algorithm makes the total curve more harmonic and it's easier to design the curve.
