Thank you for the response..<br><br>I am reading this : <a href="http://www.vtk.org/doc/release/5.6/html/a02007.html">http://www.vtk.org/doc/release/5.6/html/a02007.html</a> that I think is what I need. Because I don't have all the mapper and actor part and as it is said there, if I am not understanding wrong, vtkTransfrom work on the actor and rendering part, and vtkTransformPolyDataFilter directly on the rotation of the figure itself :<div>
