Here's my 0.02 worth...  just as VTK is not a numerical linear algebra pkg,
neither is it a (CAGD) modeling pkg.  However, I see in the 4.0 classes that
there are ruled surface and swept surface classes.

I know that the Rhino modeling pkg is quite popular (a commercial pkg):

and, there's also:

As an aside, I would also recommend Gerald Farin's book(s).  (I studied under
him and am biased I suppose).
