Hi,
There is no way to stop only one tracker, but you can stop all of them and then add one at a time. So to halt the ppt tracker you could do the following:
Code:
view = viz.get(viz.MAIN_VIEWPOINT)
#Stop all trackers
view.unlink()
#Add only the intersense tracker
view.link(intersense)
Then to resume the ppt tracker you would do this:
Code:
#Resume ppt tracker
view.link(ppt)
