[Paraview-developers] Camera Parallel Projection enable by default

[Yumin Yuan]

Or, you may be able to do the following from your own application/plugin

  vtkSMRenderViewProxy* viewproxy = mypqRenderView->getRenderViewProxy();
  pqSMAdaptor::setElementProperty(viewproxy->GetProperty("CameraParallelProjection"),
1);
  viewproxy->UpdateVTKObjects();
