Getting an object location

[Patrick]

Hey
i got a pretty similar problem, so i just add this here and hope you can help me
i want to locate both arms from my avatar, to get the distance from the Grabbing point (grabber is attached to avatars arms) to the object i want to grab.

ground = viz.addChild('ground_gray.osgb')
Heizung = viz.addChild('heiz1.osgb')
pyramid = vizshape.addPyramid(base=(0.2,0.2),height=0.2,pos=[-0.5,1.7,1],alpha=0.7)
torus = vizshape.addTorus(radius=0.1,tubeRadius=0.015,axis=vizshape.AXIS_X, pos=[0,1.7,1])
box = vizshape.addCube(size=0.1, pos=[0.5,1.7,1],alpha=0.8)
pyramid.texture(viz.addTexture('images/tile_slate.jpg'))
torus.texture(viz.addTexture('images/tile_wood.jpg'))
shapes = [Heizung,pyramid,torus,box]

these are my objects i want to grab and ground which is the base of the world

basicly what i want to do is to get the locations of both the box, pyramid, and torus shapes and from the grabber tool from my vizconnect program and give them out
