[vtkusers] delaunay constrained tesselation issue

[Sebastien MARAUX]

hello,

As you can see with the attached gif file, 
I meet problems doing a constrained
tesselation with vtkDelaunay2D :

inner polygons, whereas defined
as CW , seems to be unclosed,
ans it produces a face hole for each
inner polygon.

input data are a a vtkpolyData as input
and also the same vtkpolyData
as constraint.

the vtkPolyData contains 1CCW big
polygon closed (last point id = first
point id) and 2 CW smaller polygons
defining holes in the biggest one,
closed as well as I can see.
(3 VTK_POLYGONS type).

Is there somebody here who could
have an idea of what is happening ?

Thank you in advance 

Sebastien MARAUX
