NURBS tangent curves

Recommended Posts

Is there a secret to making NURBS curves that are tangent arcs?

 

I'm not really clear what the NurbsSetKnot does and how it affects the vertices.

You can think of the knot as the point where the mathematical function defining the curve changes (that would be the non-uniform part of Non-Uniform Rational Basis Spline). 

 

I think your best option is to create the arc via a 2D arc method, and then convert to NURBS.

Thanks, Josh.

 

Is there a way to ensure that two arcs or adjacent arc segments of a polyline are tangent?
