ARSCNViewobject rendering the scene.
The anchor for which a node is requested.
A new SceneKit node, which ARKit will add to the scene and update to follow its corresponding AR anchor.
Depending on the session configuration, ARKit may automatically add anchors to a session. ARKit also calls this method to provide visual content for any
ARAnchor objects you manually add using the session's
You can implement this method to provide a new
SCNNode object (or instance of an
SCNNode subclass) containing any attachments you plan to use as a visual representation of the anchor. Note that ARKit controls the node's visibility and its
transform property, so you may find it useful to add child nodes or adjust the node's
pivot property to maintain any changes to position or orientation that you make.
If you return
nil from this method, no node is added to the scene.
Alternatively, if you do not implement this method, ARKit creates an empty node, and you can implement the
renderer: method instead to provide visual content by attaching it to that node.
