Description:
|
The method used is equivalent to checking if the convex hull of the curve straddles any knots. It determines if the given
bs2_curve straddles any of the knot lines of the given
bs3_surface, meaning that the curve inherits the continuity degree of the B-spline surface (otherwise its infinitely continuous). It doesn't matter if occasionally it does straddle some knots when it doesn't, but the converse error is not acceptable.
