passing coordinates

[piyush]

how to pass the coordinates of position of sensor from
PPT to vizard file.?

[Jeff]

First get a handle to the PPT tracker in Vizard via VRPN:
vrpn = viz.add('vrpn7.dle')
tracker = vrpn.addTracker('PPT0@hostname',0)

Then you can print the position data every frame or write it to a text file:
def printPPTData():
print tracker.getPosition()

vizact.onupdate(0,printPPTData)
