說明

|
|
|
|
This node uses body tracking data from an :ref:`XRBodyTracker<class_XRBodyTracker>` to pose the skeleton of a body mesh.
|
|
|
|
Positioning of the body is performed by creating an :ref:`XRNode3D<class_XRNode3D>` ancestor of the body mesh driven by the same :ref:`XRBodyTracker<class_XRBodyTracker>`.
|
|
|
|
The body tracking position-data is scaled by :ref:`Skeleton3D.motion_scale<class_Skeleton3D_property_motion_scale>` when applied to the skeleton, which can be used to adjust the tracked body to match the scale of the body model.
