Regarding getting yaw, pitch, roll separately frm 'vizconnect.getEuler('trac') functn

[rajnishv]

Jeff,
One more query ,i want to re-apply the same yaw ,pitch to the head tracker but i have to restrict the roll value of the head tracker so that roll doesn't work using the code,but i m not able to get it:

#----------Start----------------
def restrictRollFromTracker():
headTracker=vizconnect.getTracker('headtracker')
eulrHeadTracker=headTracker.getEuler()
yaww=eulrHeadTracker[0]
pitchh=eulrHeadTracker[1]
headTracker.getNode3d().setEuler([yaww,pitchh,0],viz.ABS_PARENT )

vizact.ontimer(0,restrictRollFromTracker)


But i m not able to retrict the roll value of the tracker again.Pls help.
#-----End---------------



Waiting for ur reply.
Thanx & Regards!!!

In this case you don't need to get the yaw, pitch, and roll values. Just get a handle to the tracker link and use the link.setEuler operator:

trackerLink = vizconnect.getTracker('headtracker').getLink()
#Keep the incoming yaw and pitch, but zero the roll
trackerLink.setEuler([None,None,0])
