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></blockquote><div><br></div><div>It is always annoying when you have to use a filter for a non-intended use. Maybe we should wrap this vtkThreshold method of converting polydata to unstructuredgrid in a filter for this purpose like Oliver suggested? </div>
