I am creating an AR app for iOS 11 and I want to find the surface of vertical objects like a wall or any object with height. I can see there is a property for planeDetection horizontally which calls a delegate method:

- (void)renderer:(id <SCNSceneRenderer>)renderer didAddNode:(SCNNode *)node forAnchor:(ARAnchor *)anchor

So is any way to detect surface vertically?
