[vtkusers] Question about center,position and origin ?

[Dženan Zukić]

As per documentation<http://www.vtk.org/doc/nightly/html/classvtkDataSet.html>GetCenter()
returns the center of the bounding box.
As per docs <http://www.vtk.org/doc/nightly/html/classvtkProp3D.html>GetPosition
gives position (like your picture) and GetOrigin() is center of
rotation.
