[vtkusers] Re:Delaunay triangle degeneration avoidance

[Ruby Shamir]

Hi,
 
The black triangles are not holes (my background is not black).
 
However, I think it is because it could not decide the normal direction.
 
I solved this by repeating the Delaunay triangulation on the data. After
the first time I decimated, took the largest connected component and
smoothed the data.
 
Then the triangulation was better (without black triangles, and with
fewer degenerate triangles).
 
Thank you for the answer,
 
 Ruby
