I’m in the midst of updating my python code to use vtkHardwareSelector instead of vtkCellPicker to select cells because of slowness with vtkCellPicker as my models get larger. With vtkCellPicker, it was easy to get the correct cell ID. With vtkHardwareSelector, I get a cell ID, but its not one that’s in the original unstructured grid. I assume this is because it’s returning the corresponding PolyData cell ID. How do I get back to the original unstructured grid cell ids?
It looks like this issue is similar to one that was asked without an answer here: How to select a hexahedral cell using HardwareSelector
Thanks for any help,
