VTKjs release memory

Hi,
I would like to ask which is the correct method to release memory allocated by a volumeMapper.
I have a genericRenderWindow with just an actor (vtkVolume) and its mapper (vtkVolumeMapper). When I build the scene I see the memory growth, but when I destroy the context (actor.delete() and renderWindow.delete() ), the memory does not decrease.
Any hint that can put me in the right direction?
Thanks in advance,
Mattia

Did you try calling mapper.delete() ? Also in general you don’t know when the gc will actually run. I’m not sure that’s the case here or not.

Hi Sebastien and thanks for your suggestion, I had missed that!
Sorry for late answer too
