[vtkusers] set image as background

[Giancarlo Amati]

I correct... it happens that the last addRenderer prevails over the previous ones so...some how it happens that only the last one is effective.....

there must be something else.

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,
