[vtkusers] Re : Visualize the same object in 2 different windows

[C. Hiba]

Hi JohnMark. I'm Hiba.
Thank you for your help but i'm not sure that code will resolve my problem.
I visualize a 3D image in the first renderWindow of my application. I want to "import" the same image to the second renderWindow by clikcing in a buttom for example.
=> read the image form the first window and visualize it in the second
I hope i explained more the problem and i'm waiting for your help.
Thank you

Hi,
  I don't know what's your name. maybe you need two renderers in the same render window, and then you could render two different volumes in them.
  you can do like this :
  vtkRenderWindow * renWin = vtkRenderWindow::New();
  vtkRenderer * ren1 = vtkRenderer::New();
  vtkRenderer * ren2 = vtkRenderer::New();
    renWin->AddRenderer(ren1);
    renWin->AddRenderer(ren2);
    
    // your original pipeline
    ... ...
 
    ren1->SetViewport(   0,   0,  0.5,  1);
    ren2->SetViewport(0.5,   0,     1,  1);
    ... ...
    renWin->Render();
  
  using this, you could divide the whole render window into two parts, and then you could do what you want to in the two different renderer. 
  hope this could help you.
  Mark
