right-hand to left-hand coordinate System for a cave setup

I have a vicon tracking system (right-hand-coordinate-system) and I want to use this system in a cave environment. So I have to swap the position und orientation data of my vicon-body-object (“ViewTracker”).
For a “viz.link” object no problem, but how can I do this for the cave setup tracker-object?

Code:
Vicon = viz.add('vicon.dle', 0, ViconIP)
ViewTracker = Vicon.getBody(0)

cave = vizcave.Cave()
cave.addWall(PowerWall)

cave.setTracker(ViewTracker)   #ViewTracker.swapPos([3,2,-1])??? 
caveorigin = vizcave.CaveView(viewtracker)


origintracker = viztracker.KeyboardMouse6DOF()
originlink = viz.link (origintracker, caveorigin)

There are a few ways to accomplish this. I would suggest using the filter.dle plug-in:
Code:
#Create filter extension
filter = viz.add('filter.dle')

#Swap position of view tracker
ViewTracker = filter.swap(ViewTracker,pos=[3,2,-1])
