[vtkusers] set image as background

[Giancarlo Amati]

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.
Giancarlo

I do no think so, unless you have multiple renderers at the same layer, which you do not want in this case.

David,
many thanks. Just a quick questions: does in make any difference the order I add each renderer to the renderwindow?

I would have two renderers, layer 0 and layer 1, both will cover the same viewport. Put what you want to be the background on a quad or a 2D image data in layer 0 and set layer 0's camera to show it exclusively. Then render the scene in layer 1. Layer 1's





 background will not be drawn, but objects in layer 1 will appear in front of the image from layer 0.

and the rendering my dataset as usual.

Kind regards.
