[vtkusers] vtkDelaunay2D too slow

[Schober Beatrix [STEMMER IMAGING GmbH]]

Hi all,

I have a laser point cloud  (txt file with xyz values) of which I generate a vtkPolyData with points. I am running Delaunay2D on it to get a surface.

For 360.000 points vtkDelaunay2D takes around 2 minutes. As this number of points is a small point cloud, this is too long for a customer application.

Any hints, how to increase computation speed?

Thank you very much in advance!
