Displaying render information in `vtkRenderer`


I am displaying some 3d file in a vtkRenderer and I wish to know if there is a utility in the framework to directly dispay a metrics/information element in the renderer?

I saw the framerate data is available, but maybe I need to do that by myself? Asking in case I did not find in the example.

On iOS using c++.



You can use vtkCornerAnnotation to display FPS in a render window. You can find a complete implementation in CTK (https://github.com/commontk/CTK/blob/master/Libs/Visualization/VTK/Widgets/ctkVTKAbstractView.cpp).

Thankis you very much!
