[vtkusers] Re : vtkHardwareSelection on vtkUnstructuredGrid

[R M]

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

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.
