| nodeStates | A list that is populated with VR.VRNodeState objects. |
Describes all presently connected VR nodes and provides available tracking state.
Not all VR/AR platforms provide complete tracking data. Use the properties VR.VRNodeState.positionAvailable, VR.VRNodeState.rotationAvailable, etc. to determine whether specific data is available for a tracked node. Also, this method will clear any members of the List passed before populating it.
