The example below links the hand to a keyboard tracker and keeps it in the reference frame of the main view:
Code:
import viz
viz.go()
import vizinfo
vizinfo.add("To move the hand use 'a/d' left/right, 'w/s' forward/back, 'r/f' up/down")
import viztracker
keyTracker = viztracker.KeyboardPos()
hand = viz.addAvatar('hand.cfg')
ground = viz.addChild('tut_ground.wrl')
link = viz.link(keyTracker,hand)
link.preTrans([0.2,0,1])
link.postMultLinkable(viz.MainView)
