You can do something like this:

    writer = vtkPolyDataWriter()
    if best_distance == distance_before_align:
        writer.SetInputData(original_source_polydata)
    elif best_distance == distance_after_align:
        writer.SetInputData(source_polydata)
    else:
        writer.SetInputData(transform.GetOutput())
    writer.SetFileName('AlignedSource.vtk')
    writer.Write()
    writer.SetInputData(tpd.GetOutput())
    writer.SetFileName('Target.vtk')
    writer.Write()

This will give you the aligned source and target as VTK files that you could load into ParaView.
