Is there documentation or could anyone tell me about the algorithm behind the sample method please? Following the example and doing
result = mesh_orig.sample(data_to_probe)
where data_to_probe contains cell_array data, gives a point_array in result.
Is this new data computed from by nearest neighbor values, average of all points of data_to_probe that lie within each cell of mesh_orig, weighted average of the fraction of cells that lie within the new cells, linear interpolation onto the nodes of mesh_orig, or something else entirely?
I reviewed vtkResampleWithDataSet.cxx, but it was not at all obvious what was happening with all the inheritance and it does not appear that any actual resampling happens within this file.
