Importing Vicon Tracker Data

Hello,

I found the same issue for Version 3.0. I'm using Vizard 4.0 in the 90days Trial Version.

I want to get the data of segments and markers tracked with Vicon Tracker 2.0 (32Bit). I had some warnings and errors. They were solved by opening the port 800 in the Windows Firewall at the Vizard PC.

If I run the following code, a new window opens, and Shows the World Viz logo on a black Background. The Interactive window stops at loading the Basketball.osgb.



import viz

viz.go()

# Add a world
scene = viz.addChild('dojo.osgb')
ball = viz.addChild('basketball.osgb')
ball.setPosition([1,1,1])

vicon = viz.add('vicon.dle',0,'192.168.10.1')
body = vicon.getBody(0)
marker = vicon.getMarker(0)

print body.getName()
print marker.getName()

************************************************** ****************************
** Loading ‹bung_Vizard_1.py
************************************************** ****************************
Loading File: dojo.osgb
Loading File: basketball.osgb


On the Nexus PC I allowed Tracker to send and recieve data through the Firewall. In an other post somebody said to allow "kinematic data" as an Output. I don't know where to find that.

Thank you for your help!

The vicon plug-in works with a protocol used by earlier versions of Tracker. You should be able to use vrpn to read body data from tracker in Vizard once you specify the correct VRPN source.

Code:
import viz
import vizact
import vizshape

viz.go()

VRPN_SOURCE = 'Tracker0@localhost'

viz.move([0,-1,-5])

axes = vizshape.addAxes(length=0.5)

vrpn = viz.add('vrpn7.dle')
headtracker = vrpn.addTracker(VRPN_SOURCE)
headtracker.swapPos([-1,3,-2])

viz.link(headtracker,axes)

def showData():
	print headtracker.getPosition()
	print headtracker.getEuler()
	
vizact.ontimer(1,showData)

Hello Jeff,

thank your for your reply. First I used your code with 'Tracker0@192.168.10.1'. I thought Tracer0 referes to Vicon Tracker. Finally I tried to Import one Object I'm tracking with Tracker called Flasche (=bottle) instead of Tracker0. Now it works well.

So I have to Import every object I want to use, separately?

Code:

import viz
import vizact
import vizshape

viz.go()


VRPN_SOURCE = 'Flasche@192.168.10.1'
scene = viz.addChild('dojo.osgb')
viz.move([0,-1,-5])

axes = vizshape.addAxes(length=0.5)

vrpn = viz.add('vrpn7.dle')
flasche = vrpn.addTracker(VRPN_SOURCE)
flasche.swapPos([-1,3,-2])

viz.link(flasche,axes)

def showData():
print flasche.getPosition()
print flasche.getEuler()

vizact.ontimer(1,showData)



Thank you very much!

ChrisMa

Yes, you must connect to each rigid body separately.
