Hello fellow developers, When attempting to merge single rooms into one model, the resulting floorplan I got appears to have rooms stacked on top of each other. I am using a single ARSession for all the scans, to my understanding, the world coordinate system remains consistent during a continuous ARSession. I can't figure out why the rooms are overlapping or positioned vertically on top of each other in the generated floorplan. I am uncertain whether this issue stems from my own code implementation. I did the following modification to the sample code Initiated an ARSession in RoomCaptureViewController private var arWorldTrackingConfig: ARWorldTrackingConfiguration = ARWorldTrackingConfiguration() private var arSession: ARSession = ARSession() Pass ARSession to roomCaptureView private func setupRoomCaptureView() { arSession.run(arWorldTrackingConfig) roomCaptureView = RoomCaptureView(frame: view.bounds, arSession: arSession) roomCaptureView.captureSession.delegate = self roomCaptureView.delegate = self view.insertSubview(roomCaptureView, at: 0) } Pause the ARSession after completion of scanning one room private func saveSession() { isScanning = false roomCaptureView?.captureSession.stop(pauseARSession: false) setCompleteNavBar() } @IBAction func saveScanning(_ sender: UIBarButtonItem) { if isScanning { saveSession() } else { cancelScanning(sender) } self.exportButton?.isEnabled = false self.activityIndicator?.startAnimating() } Any experiences or insights are greatly appreciated.
