Iterative Least Square Optimization for the Weights of NURBS Curve

Algorithm 2

Pseudocode version of fitting skinned surface with proposed method.

 {u direction fits}

 Set the number of knots in the u direction and generate a uniform knot vector.

 for i = 1 to l do

  Fit the ith row data points and get a NURBS curve in the proposed method.

 end for

 { direction fits}

 Set the number of knots in the direction and generate a uniform knot vector.

 for i = 1 to m do

  Fitting the ith column control points of every NURBS curve in 4 dimensions.

 end for

 {generate surface}

 Generate the NURBS surface using the control points obtained in direction fitting and the knot vectors of u and direction.
