[vtkusers] Properly using vtkTransformFilter & vtkTransform...

[Sebastien Auclair]

Hi !

Me again with my philosophical questions !

If we're using vtk not only to display but to modify data, is using
vtkTransform & vtkTransforFilter the correct approach ?
(As explained at page 80 of "The visualization Toolkit; User's Guide" from
Kitware)

If yes, should we create our own sub-class of vtkRenderWindowInteractor to
call these transformation classes ?
Is there an example of that ?

For instance, we need to implement a scaling operation on shapes created
from grids (Rect, struct or Unstruct...). I suppose that we will disconnect
the scaling operation as implemented by the regular
vtkRenderWindowInteractor ...(Which only operates on the vtkActor3D....)

Again, where can we find a code example for such CAD application and needs ?

Thanks in advance !
