Hi,<br>I feel surprised about the conversion from PolyData to UnstructuredGrid<br>posts: I didn't see them!<br><br>I have a quite fast solution, I don't know it is suitable for you:<br>just pass your polydata in a vtkThreshold, with thresholds being set<br>
to actual min and max values of any of your data array. If you don't<br>have any array, just add a vtkGenerateIndexArray before the threshold<br><br>note: you can easily check this pipeline with paraview:<br>
Sphere Source -> Generate Point Ids -> Threshold<br><br>HTH<br>Jerome<br><br><div class="gmail_quote">2010/3/19 Oliver Rudolph <span dir="ltr"><<a href="mailto:oliver.rudolph@iisb.fraunhofer.de">oliver.rudolph@iisb.fraunhofer.de</a>></span><br>

<br>
There had been several postings on conversion from vtkPolyData to<br>
vtkUnstructuredGrid in the past with no really accessible solutions<br>
except the global statement "write a filter on your own".<br>
<br>
Now, I was confronted with doing quite the same conversion and found a<br>
rather quick solution doing some 3D delaunization. Although this is not<br>
yet stable in all situations there are, "normal" input as I had been<br>
confronted with up to know, worked well.<br>
<br>
Maybe you have suggestions for improvement or other approaches to this<br>
problem. So far, please find attached the source files, maybe you'll<br>
want to add them to the vtk codebase (which would make me a little proud :)<br>
<br>
<br>
Best regards,<br>
