<brief_description >
A tracked hand in XR.
</brief_description>
<description >
A hand tracking system will create an instance of this object and add it to the [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 [XRHandModifier3D] to animate a hand mesh using hand tracking data.
