Hello all!

For the same geometry design project as I mentioned before, I'm interested
in *sampling curves*.

*Question 1:* Does it exist any CGAL algorithm for sampling curves
independently from their traits class? ... Or at least, for sampling both
polylines and bezier curves.

*Question 2:* Actually, any reference about any CGAL 2D curve sampling
method is welcome :o)

From this point of my message, there is no more about my questions. The
following lines are for anyone wanting a bit more of details about my
motivation. Given a curve (the big one looking like a tentacle in the
attached image), I want to place other curves along it. (the little ones
there)

This kind of method looks simple, but permits to create nice NPR effects
with "graftal" methods, which consist in pasting fur / grass / any elements
along silhouette curves of objects. For this purpose, it is important to
control the distribution of these elements... And the sampling method,
consequently.

In this example, my curve is under Bézier's representation and I sample it
with uniform parametrization intervals. Most basic method ever. For getting
more various and controlled results, I would like to allow access to better
curve sampling algorithms.

Thanks for any help!
