> I understand your concern. The wiki page does document this very well. But
typically the interactor styles help you choose what  type of interaction
you want to do. If you want head tracking use the vtkVRStyleTracking which
uses tracking data 'cspad.head' and changes the property
RenderView1.HeadPose (in the state file)

If your scene has a  slice and you want to manipulate the slice then you
can use  vtkVRStyleGrabNTranslateSliceOrigin style. It basically takes
tracker inputs and a button to change the slice origin
(CutFunction.Origin). So you can press button and move the wand to move the
slice plane.

I will be updating the document with more info about the interactor styles.

 thank you for your help
