So, since I have not yet find any solution, my question is: what vtkMapper
should I use to display vtkMultiBlockDataSet of unstructuredGrid in order to
select cells or points and extract this selection ?
Thank you

Objet : [vtkusers] vtkHardwareSelection on vtkUnstructuredGrid
Hello,
Here's my problem, I want to select cells from vtkUnstructuredGrid using
vtkHardwareSelector but this does not work.
I have seen on this link
http://www.vtk.org/doc/nightly/html/classvtkHardwareSelector.html#details that
"If you need to select other data types, consider using vtkDataSetMapper and
turning on it's PassThroughCellIds feature, or using vtkFrustumExtractor".
But where I enable the PassThroughCellIds feature and how should I use
vtkFrustumExtractor.
I have tried with vtkAreaPicker using vtkDataSetMapper but no result.
Thank you for your help.
