A bit of progress.

The number on the image is the order (aka degree+1) of the curve used in the Nurbs.

I hope you are ready to handle the knot vectors, because I gave up the
user-friendliness of opened/clamped/closed

nu7 is similar to the rational bezier that was previously available. (because with 7
control points, at order 7, the nurbs (with the knot vectors that were provided) is a
single rational bezier)

nu3 is more similar to your provided picture, or it could be nu4.



Still to do: implement the computation of normal (I found a nice formula, but I lack
the time to code it), not used so far.

Also attached is the SDL scene with what is the equivalent of Jar-Jar in front of the
Chamber:
I do not know yet who is Palpatine, but there is a big step towards the dark side of
the Force.

Because the nurbs is transformed into a mesh (in the SDL so far).
