To get the absolute position, traverse the scenegraph and add all the vectors together that precede the target object. ie. Call it on the root, then the child of the root, etc.
No that is not correct. The transforms can be rotated and/or scaled, in that case it will not work to just combine all the positions.
Instead you should call getLocalToVworld(t) on the node to get its absolute transform, then extract the position from that.
