	angularVelocity		Sets the vector representing the current angular velocity of the tracked node.
	nodeType		The type of the tracked node as specified in XRNode.
	position		Sets the vector representing the current position of the tracked node.
	rotation		Sets the quaternion representing the current rotation of the tracked node.
	tracked		Set to true if the node is presently being tracked by the underlying XR system, and false if the node is not presently being tracked by the underlying XR system.
	uniqueID		The unique identifier of the tracked node.
	velocity		Sets the vector representing the current velocity of the tracked node.
