Hi,

I found that vtkProbeFilter, since vtk8.2 uses by default a vtkStaticCellLocator. That breaks some of my tests. So I propose either of these two options:

1. Modify vtkStaticCellLocator::FindCell() to use the this-\>DataSet-\>FindCell()
2. Modify vtkProbeFilter to not use vtkStaticCellLocator if no CellLocatorPrototype is used and use the DataSet-\>FindCell() method.
  - Merge Request: [https://gitlab.kitware.com/vtk/vtk/merge\_requests/5556](https://gitlab.kitware.com/vtk/vtk/merge_requests/5556)

I would like to apply the fix to 8.2 if possible.

I’m working in the Pull Requests in the meanwhile.

Cheers,
