com.jme3.math.Quaternion.lookAt()
lookAt is a convienence method for auto-setting the quaternion based on a direction and an up vector. It computes the rotation to transform the z-axis to point into 'direction' and the y-axis to 'up'. @param direction where to look at in terms of local coordinates @param up a vector indicating the local up direction. (typically {0, 1, 0} in jME.)

                localLocation.divideLocal(spatial.getParent().getWorldScale());
                tmp_inverseWorldRotation.set(spatial.getParent().getWorldRotation()).inverseLocal().multLocal(localLocation);
                spatial.setLocalTranslation(localLocation);


                if (useViewDirection) {
                    localRotationQuat.lookAt(viewDirection, Vector3f.UNIT_Y);
                    spatial.setLocalRotation(localRotationQuat);
                }
            } else {
                spatial.setLocalTranslation(getPhysicsLocation());
                localRotationQuat.lookAt(viewDirection, Vector3f.UNIT_Y);
