Problem reading VRPN info from ZSpace

Your while loop is blocking the main update loop, so the tracker will never update. You should never use time.sleep in the main thread. Instead, register a function to be called every 0.25 seconds and print the tracker values within that function:

import vizact
def PrintValues():
    print glasses.getPosition()
    print glasses.getQuat()

vizact.ontimer(0.25,PrintValues)

Thanks! That did the trick.
