Polhemus Fastrak Vizard

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.

See the notes on the Polhemus page regarding the fastrak connection. In order for Vizard to connect to the sensors, PiMgr should not be running. The following code will print out the data each frame once a connection is made.

Code:
import viz
import vizact
viz.go()

polhemus = viz.add('polhemus.dle') 
sensor = polhemus.addFastrak()

def printData():
	pos = sensor.getPosition()
	ori = sensor.getEuler()
	print 'pos',pos
	print 'ori',ori

vizact.onupdate(0,printData)
Also, take a look at vizconnect for setting up up a configuration file that connects to the sensor.

thank you!

I am facing one more issue. Vizard movements are not the same as my movement along x,y,z in physical world. Is there some calibration required. How do I do it?
