Properties
Offset applied to the elbow position as the controller is rotated upwards.
Declaration
public Vector3 armExtensionOffset { get; set; }
Property Value
Declaration
public Vector3 controllerPosition { get; }
Property Value
Position of the controller joint relative to the wrist before the arm model is applied.
Declaration
public Vector3 controllerRestPosition { get; set; }
Property Value
Declaration
public Quaternion controllerRotation { get; }
Property Value
Ratio of the controller's rotation to apply to the rotation of the elbow.
The remaining rotation is applied to the wrist's rotation.
Declaration
public float elbowBendRatio { get; set; }
Property Value
Declaration
public Vector3 elbowPosition { get; }
Property Value
Position of the elbow joint relative to the head before the arm model is applied.
Declaration
public Vector3 elbowRestPosition { get; set; }
Property Value
Declaration
public Quaternion elbowRotation { get; }
Property Value
the pose which represents the final tracking result of the arm model
Declaration
public Pose finalPose { get; set; }
Property Value
The game object which represents the "head" position of the user
Declaration
public XRNode headGameObject { get; set; }
Property Value
If true, the root of the pose is locked to the local position of the player's neck.
Declaration
