Web12 nov. 2015 · Abstract In this paper, estimated curve Knot points are found for B- Spline Curve by using Niched (Celled) Pareto Genetic Algorithm which is one of the multi objective genetic algorithms. It is necessary to know degree of the curve, control points and knot vector for drawing B-Spline curve. Web1 jun. 2007 · In the knot placement, the knots are determined by averaging the parameter values of the dominant points, which basically transforms B -spline curve fitting into the problem of dominant point selection. We describe the properties of the knot placement including the property of local modification useful for adaptive curve refinement.
