[vtkusers] set image as background

[Giancarlo Amati]

Yup, it's roughly the same structure my code has.
But apparently whatever is the order or the AddRenderer..... the one containing the image seems prevailing over the other one 

Many thanks anyway!

mmm now it get confusing because that's the style of my code:

this is the declaration:
    vtkSmartPointer<vtkRenderer> L0= vtkSmartPointer<vtkRenderer>::New();

    vtkSmartPointer<vtkCamera> camL0 = vtkCamera::New();




    vtkSmartPointer<vtkRenderer> L1 = vtkSmartPointer<vtkRenderer>::New();
    vtkSmartPointer<vtkCamera> camL1 = vtkCamera::New();
    

    vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();



    renderWindow->SetSize(720,576);
 

Than I create a plane with texture the image I load up and then... I add the plane to L1;
L0->AddActor(Scene);
L1->AddActor(texturedPlane);

renderWindow->AddRenderer(L0);



renderWindow->AddRenderer(L1);

and I call start() of the interactor.

but I just got my Texture rendered..but not the 3D Model. so what u mean with Layers?

Regards.

I tried to make a demo of this:http://www.vtk.org/Wiki/VTK/Examples/BackgroundImage

However, it seems like one renderer covers up the other. For now it is just trying to display an ImageActor in backgroundRenderer and then a sphere in sceneRenderer.Thanks,
