me.         


        

Answer 1

object.position is always local to the object. If you want to get the position in world space you need to get it from object.matrixWorld.

Try with this:

scene.add(objMesh);
scene.updateMatrixWorld(true);
var position = new THREE.Vector3();
position.getPositionFromMatrix( objMesh.matrixWorld );
alert(position.x + ',' + position.y + ',' + position.z);

Update:

The function getPositionFromMatrix() has been renamed to setFromMatrixPosition().
