[vtkusers] (constrained) delaunay2D issue

[Sebastien MARAUX]

Moreover, why does vtkDelaunay2D handle this polygons 
such badly.

I think it could be considered as a bug , isn't it ?
Is there a way to fix it, even with a 1 day dev.

Or I would like to understand why this polygons are 
triangulated like this ?

  Hello

  I am using Delaunay2D for triangulating polygons 
  (representing dB levels around airports).

  I prefer this way to tesselate method as it can deal with 
  holes.

  For a special dB level, I can have several polygons defining islands and holes (depending on polygon orientation).

  So I set the polydata as input and as source, so that holes are taken off the object.

  1. there is an issue using this method with most of my 
  polygons : I can obtain "wrong" triangles being holes instead 
  of filled (see enclosed) How can I fix it ?

  2. Is there other ways of dealing with holes, based on 
  tesselate, which would be faster than  this delaunay 
  method?

  Thank you in advance
