XRHandModifier3D
|

================
|
|
|
|
**继承：** :ref:`SkeletonModifier3D<class_SkeletonModifier3D>` **<** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
|
|
|
|
用于从 :ref:`XRHandTracker<class_XRHandTracker>` 数据驱动手部网格的节点。

描述
|
|
----
|
|
|
|
该节点使用来自 :ref:`XRHandTracker<class_XRHandTracker>` 的手部跟踪数据来设置手部网格的骨架。
|
|
|
|
通过创建由相同 :ref:`XRHandTracker<class_XRHandTracker>` 驱动的手部网格的 :ref:`XRNode3D<class_XRNode3D>` 祖先来定位手部。
|
|
|
|
当将手部跟踪位置数据应用于骨架时，它会根据 :ref:`Skeleton3D.motion_scale<class_Skeleton3D_property_motion_scale>` 进行缩放，可用于调整跟踪的手部以匹配手部模型的缩放。
