Description

Describes the state of a node tracked by a XR system. .

acceleration	Sets the vector representing the current acceleration of the tracked node.
angularAcceleration	Sets the vector representing the current angular acceleration of the tracked node.
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.

TryGetAcceleration	Attempt to retrieve a vector representing the current acceleration of the tracked node.
TryGetAngularAcceleration	Attempt to retrieve a Vector3 representing the current angular acceleration of the tracked node.
TryGetAngularVelocity	Attempt to retrieve a Vector3 representing the current angular velocity of the tracked node.
TryGetPosition	Attempt to retrieve a vector representing the current position of the tracked node.
TryGetRotation	Attempt to retrieve a quaternion representing the current rotation of the tracked node.
TryGetVelocity	Attempt to retrieve a vector representing the current velocity of the tracked node.
