Polhemus Fastrak Vizard

[harshad]

import viz
polhemus = viz.add('polhemus.dle')
sensor = polhemus.addFastrak()
data = sensor.getData()
print(data)

--------------------------------------

getData() function returns empty list.


I wish to interact with a virtual environment made in Vizard. I am using polhemus fastrak. Please provide step by step guide to interface sensor with vizard.
