[vtkusers] Frustum and vtkInteractorStyleRubberBand3D question

[R M]

Hello,

I use vtkInteractorStyleRubberBand3D in order to extract cells of my geometry using the frustum.
The lonely things I haveseen in vtkInteractorStyleRubberBand3D is the start and end position of the rectangle.
So, How can I create the frustum to extract my geometry ?

With vtkInteractorStyleRubberBandPick I have use vtkPlanes* frustum = static_cast<vtkAreaPicker*>(this->GetInteractor()->GetPicker())->GetFrustum(); 
Like in the example http://www.vtk.org/Wiki/VTK/Examples/Cxx/Picking/HighlightSelectedPoints
But with vtkInteractorStyleRubberBand3D it doesn't work.

Any idea for creating a frustum when using vtkInteractorStyleRubberBand3D ?


Thank you
