Mismatched Translation Between Real Motion and Display

[Jeff]

It should not be necessary to make any modifications to the coordinate system in Vizard. Try testing with the following script after specifying the correct hostname:

import viz
viz.go()

viz.addChild('piazza.osgb')

opto = viz.add('optotrak.dle',0,'192.168.0.114') 
body = opto.getBody(0)

viz.link(body,viz.MainView)

This video tutorial is quite old but it may help with the optotrack setup.
