Follow-up Comment #6, bug #45295 (project octave):
Hi,
thanks for your replies.
@Carlo: What I've done is the following; take the initial NURBS surface,
insert knots until i have Bezier patches and then extract those patches.
Bezier patches have C_inf continuity. This should also be true for the
rational case.
@Rafa: I have had the same impression. I wasn't sure though. I was a bit
irritated by the NaN and Inf entries and the issued warnings.
In order to resolve this issue, maybe outputting a warning would be the best
way to go. What do you think?
Sven
