Hi Yoshimi, The Clean to Grid filter internally invokes vtkCleanUnstructuredGrid which can merge duplicate points, but they need to have coincident coordinates. In contrast, very old versions of ParaView also merged very close points, but that is not true any more, see closed issue http://www.paraview.org/Bug/view.php?id=9728
It is actually very simple to derive a (c++-based) plugin from vtkCleanUnstructuredGrid that provides a filter that merges points within a distance of less than a (configurable) fraction of the length of the diagonal of the bounding box of the data set. But in order to be able to use said plugin you would need to compile ParaView from source. Not sure whether you would want to go to such lengths.
