Discussion

The value for this key is an SCNNode object. Hit-testing searches only the child node hierarchy under this node. When hit-testing takes place in the screen space of an SCNSceneRenderer object with the hitTest(_:options:) method, the default value is the presented scene’s root node. When hit-testing is in a node using its hitTestWithSegment(from:to:options:), the default value is the node.
