Hi yeonchool,<br>
<br>
vtkActor.SetPosition() simply effects where your actor is rendered, but do<br>
not modify any coordinates of the underlying polydata physically.<br>
Therefore you should use SetCenter() like you do or better apply a<br>
vtkTransformFilter to modify point coordinates actually.<br>
<br>
You may have a look at the doxygen manpage for vtkTransfromFilter, where<br>
this behaviour is explained.<br>
<br>
with best regards<br>
