Hi,
Are you using the bird/intersense for head tracking? If so, then you can use the following code to use the bird position and intersense orientation for head tracking:
Code:
bird = viz.add('flockofbirds.dls')
isense = viz.add('intersense.dls')
#Create new tracker object that gets position from bird and rotation from isense
headTracker = viz.mergeLinkable(bird,isense)
#Link tracker to main view
viz.link(headTracker,viz.MainView)
