Method Detail

rendererDidAddNodeForAnchor

default void rendererDidAddNodeForAnchor(SCNSceneRenderer renderer,
                                         SCNNode node,
                                         ARAnchor anchor)

Called when a new node has been mapped to the given anchor.

Parameters:

renderer - The renderer that will render the scene.

node - The node that maps to the anchor.

anchor - The added anchor.

rendererDidRemoveNodeForAnchor

default void rendererDidRemoveNodeForAnchor(SCNSceneRenderer renderer,
                                            SCNNode node,
                                            ARAnchor anchor)

Called when a mapped node has been removed from the scene graph for the given anchor.

Parameters:

renderer - The renderer that will render the scene.

node - The node that was removed.

anchor - The anchor that was removed.

rendererDidUpdateNodeForAnchor

default void rendererDidUpdateNodeForAnchor(SCNSceneRenderer renderer,
                                            SCNNode node,
                                            ARAnchor anchor)

Called when a node has been updated with data from the given anchor.

Parameters:

renderer - The renderer that will render the scene.

node - The node that was updated.

anchor - The anchor that was updated.

rendererNodeForAnchor

default SCNNode rendererNodeForAnchor(SCNSceneRenderer renderer,
                                      ARAnchor anchor)

Implement this to provide a custom node for the given anchor. This node will automatically be added to the scene graph. If this method is not implemented, a node will be automatically created. If nil is returned the anchor will be ignored.

Parameters:

renderer - The renderer that will render the scene.

anchor - The added anchor.

Returns:

Node that will be mapped to the anchor or nil.

rendererWillUpdateNodeForAnchor

default void rendererWillUpdateNodeForAnchor(SCNSceneRenderer renderer,
                                             SCNNode node,
                                             ARAnchor anchor)

Called when a node will be updated with data from the given anchor.

Parameters:

renderer - The renderer that will render the scene.

node - The node that will be updated.

anchor - The anchor that was updated.
