XRHandTracker
=============

**Inherits:** :ref:`XRPositionalTracker<class_XRPositionalTracker>` **<** :ref:`XRTracker<class_XRTracker>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A tracked hand in XR.

.. rst-class:: classref-introduction-group

Description
-----------

A hand tracking system will create an instance of this object and add it to the :ref:`XRServer<class_XRServer>`. This tracking system will then obtain skeleton data, convert it to the Godot Humanoid hand skeleton and store this data on the **XRHandTracker** object.

Use :ref:`XRHandModifier3D<class_XRHandModifier3D>` to animate a hand mesh using hand tracking data.
