it is unable to track position but runs without any errors import viz viz.go() piazza = viz.addChild('maze.osgb') viz.MainView.move([3,2,8]) vrpn = viz.add('vrpn7.dle') posTracker = vrpn.addTracker('PPT0@WORLDVIZ-PC',0) #Connect to Intersense on local machine running Vizard isense = viz.add('intersense.dle') oriTracker = isense.addTracker() #Create a 6DOF tracker by merging position data from PPT with #Orientation data from Intersense headTracker = viz.mergeLinkable(posTracker,oriTracker) #Link viz.MainView with headTracker headlink = viz.link(headTracker, viz.MainView) #Once the user is facing PPT north pressing the 'r' key will align #Intersense's coordinate system with PPT's coordinate system vizact.onkeydown ('r', oriTracker.reset) data=headlink.getData() print data |
