Two options:

1. on live Node (say, Shape3D) use getLocalToVworld() and you will get accumulated Transform3D for the node. This will give you position of the center of local coordinates.

2. Use getVworldBounds() on live Node to get BoundingSphere, so you can get coordinates of the center of your object.

Transform3D loc = new Transform3D();
Vector3f q1 = new Vector3f();
bRoteGroup.getLocalToVworld(loc);
loc.get(q1);
return(new float[] {q1.x,q1.y,q1.z});

i still get 0,0,0 Sad

Can you make a test case, so I can take a look?

This is strange that getLocalToVworld does not work. Are you sure that you are doing this on live Node?
