[vtkusers] 2 rendering windows same camera

[Benoit Regrain]

Hi,

To do this, you will use the vtkCommand class (or vtkCallbackCommand).

When you make an interaction in one frame, some event are sent by vtk. 
And when this event is sent, a callback function (when using vtkCallbackCommand)
or class (derived from vtkCommand) is called corresponding to sended event.

When seeing the documentation on the vtkCommand class, you have the list of 
all event that occur in vtk.

Cheers
Benoit

  Subject: [vtkusers] 2 rendering windows same camera


  Dear List: 

  I have 2 rendering windows controlled with the same camera. In this way, whenver I interact with the first window, the similar effect can be observed in the 2nd windows. however, i have to click first on the 2nd window in order to see the results (refresh) which is not what I expected. I want the results to be observable SIMULTANEOUSLY in the 2nd window. So, in real-time. Have any ideas please ? 
  Here is my relevant source code: 

  renderer->SetBackground(0.0, 0.0, 0.0); 
  renderer->AddVolume(volume); 
  renderer->GetActiveCamera()->Azimuth(20.0); 
  renderer->GetActiveCamera()->Dolly(1.60); 
  renderer->ResetCameraClippingRange(); 
  renwin->AddRenderer(renderer); 
  iren->SetRenderWindow(renwin); 


  vtkLight *pLight = vtkLight::New(); 
  renderer2->SetActiveCamera(renderer->GetActiveCamera()); 
  pLight->SetPosition(renderer->GetActiveCamera()->GetPosition()); 
  renderer->AddLight(pLight); 
  renderer2->AddLight(pLight); 

  renderer2->SetBackground(0.0, 0.0, 0.0); 
  renderer2->AddVolume(volume); 
  renderer2->ResetCameraClippingRange(); 
  renwin2->AddRenderer(renderer2); 
  iren2->SetRenderWindow(renwin2); 

  Thanks, 
  Radu.
