[vtkusers] Fill vtkSpline contour

[Enzo Matsumiya]

Hello,

I have a set of points which are used to construct splines
(vtkCardinalSpline) on my scene.
I'm using vtkLineSource + vtkCardinalSpline + vtkSplineFilter to display
it, and it's working fine.

They form some sort of closed contours.

Now I need to fill this structures in some way. I have tried using
vtkDelaunay3D, based on this example:

http://www.paraview.org/Wiki/VTK/Examples/Boneyard/Cxx/PolyData/ConvexHullDelaunay3D

It really fills some of my structures, but it doesn't do it correctly. I
think the problem might that I have some structures that are apart from
each other, but inside the same actor.

How else could I achieve this?


Thanks in advance.
