WebFor example, if a degree 3 NURBS curve with 7 control points has knots 0,0,0,1,2,3,4,4,4, then the curve has uniform knots. The knots 0,0,0,1,2,5,6,6,6 are not uniform. Knots that are not uniform are called non‑uniform. The N and U in NURBS stand for non‑uniform and indicate that the knots in a NURBS curve are permitted to be non-uniform ... WebDescription. draw_nurbs returns the contour ContOut and control information ( Rows, Cols, and Weights) of a NURBS curve of degree Degree, which has been created interactively by the user in the window WindowHandle. For additional information concerning NURBS curves, see the documentation of gen_contour_nurbs_xld.
