Third-Order Non-Uniform Rational B-Spline Curve Fitting Based on Method of Accumulating Chord Length

YE Li,XIE Ming-hong (College of Mechanical Engineering and Automation,Huaqiao University,Quanzhou 362021,China)  
According to a given set of data points of the third-order non-uniform rational B-spline(NURBS) curve,the parametrization method of accumulating chord length which is more effective is used to construct the knot vectors to obtain the B-spline basis.All of the control points are calculated using the matrix of the control points with powers to fit the required curve finally.The final result reveals that data distribution according to the chord length can be shown by this method.This method can be used in parameter calculation during construction of the knot vector of any order NURBS curve,and can be better fit for engineering practice.
