Nurbs algorithm
WebDe Boor's algorithm also works for NURBS curves. We just multiply every control point by its weight converting the NURBS curve to a 4D B-spline curve, perform de Boor's algorithm on this 4D B-spline curve, and then project the resulting curve back by dividing the first three components with the fourth and keeping the fourth component as its new ... Web21 okt. 2024 · Curve and surface fitting technology is one of the key technologies of 3-dimensional modeling and 3-dimensional design technique. Based on the B-spline method and the corresponding boundary conditions, the method and steps of a cubic NURBS curve and surface fitting were presented in this paper. And then the algorithm was verified by …
