I have seen how I can place points on a VTK object using seed widget from : http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/vtkSeedWidget
I have also seen how I can rotate an object from : http://www.cmake.org/Wiki/VTK/Examples/Cxx/Qt/SideBySideRenderWindows
I am wondering how I can combine this so I can rotate the object when I drag, and place points when I click
