[vtkusers] convert polydata to unstructured grid

[Dominik Szczerba]

Hi,

I was wondering if there is a clean way to convert a general polydata surface 
to unstructured grid. Triangle filters will force simplices on output while I 
have quads in the surface mesh that I want to preserve. Of course I can 
achieve it by e.g. Threshold or Extract filters (thresholding nothing or 
extracting everything) but I was wondering if there is a better way.

regards,
Dominik
