Hi Jean-Noel,
Thank you very much for the assistance. I was able to retrieve the
camera data and use it in my filter.
For everyone else here is the working block of code to get camera data
directly.
pqView *view = 0;
pqActiveObjects* tempInstance = &( pqActiveObjects::instance() );
view = tempInstance->activeView();
vtkCamera* camera = vtkSMRenderViewProxy::SafeDownCast(
view->getViewProxy() )->GetActiveCamera();

I forgot to mention that "this->viewProxy" is a vtkSMRenderViewProxy*

You can access the active camera this way :
pqView *view = 0;
view = pqActiveObjects::instance().activeView();
this->viewProxy = 0;
this->viewProxy = vtkSMRenderViewProxy::SafeDownCast(
view->getViewProxy());
vtkCamera* camera = viewProxy->GetActiveCamera();
Hope it helps =)

Hello,
I have been working on a c++ paraview filter and would like to
modify output data based on the camera view
direction/location. For example, I may want to highlight data
closer to the viewer and remove far away data. Is it possible
to access some of this information (like camera location, view
direction, etc.) from a filter? I've seen some information on
accessing this data in python, but I want to get it in a
compiled c++ filter.
Thank you,
Alex
