I am making an app with RoomPlan using the official sample code. A model of the room is generated as it is scanned, and when the scan is complete, chairs and other objects are aligned parallel to the desk. I wanted to stop this behavior, so I decided to use the option beautifyObjects. import UIKit import RoomPlan class RoomCaptureViewController: UIViewController, RoomCaptureViewDelegate, RoomCaptureSessionDelegate { @IBOutlet var exportButton: UIButton? @IBOutlet var doneButton: UIBarButtonItem? @IBOutlet var cancelButton: UIBarButtonItem? @IBOutlet var activityIndicator: UIActivityIndicatorView? private var isScanning: Bool = false private var roomCaptureView: RoomCaptureView! private var roomCaptureSessionConfig: RoomCaptureSession.Configuration = RoomCaptureSession.Configuration() private var roomBuilder: RoomBuilder! private var processedResult: CapturedRoom? private var finalResults: CapturedRoom? override func viewDidLoad() { super.viewDidLoad() // Set up after loading the view. setupRoomBuilder() setupRoomCaptureView() activityIndicator?.stopAnimating() } private func setupRoomBuilder() { let beautifyObjectsEnabled = UserDefaults.standard.bool(forKey: "beautifyObjectsEnabled") if beautifyObjectsEnabled { roomBuilder = RoomBuilder(options: [.beautifyObjects]) } else { roomBuilder = RoomBuilder(options: []) } } private func setupRoomCaptureView() { roomCaptureView = RoomCaptureView(frame: view.bounds) roomCaptureView.captureSession.delegate = self roomCaptureView.delegate = self view.insertSubview(roomCaptureView, at: 0) } override func viewDidAppear(_ animated: Bool) { super.viewDidAppear(animated) startSession() } override func viewWillDisappear(_ flag: Bool) { super.viewWillDisappear(flag) stopSession() } private func startSession() { isScanning = true roomCaptureView?.captureSession.run(configuration: roomCaptureSessionConfig) setActiveNavBar() } private func stopSession() { isScanning = false roomCaptureView?.captureSession.stop() setCompleteNavBar() } // Decide to post-process and show the final results. func captureView(shouldPresent roomDataForProcessing: CapturedRoomData, error: Error?) -> Bool { Task { do { let capturedRoom = try await roomBuilder.capturedRoom(from: roomDataForProcessing) DispatchQueue.main.async { self.finalResults = capturedRoom self.exportButton?.isEnabled = true self.activityIndicator?.stopAnimating() } } catch { print("Error processing room data: \(error.localizedDescription)") } } return true } // Access the final post-processed results. func captureView(didPresent processedResult: CapturedRoom, error: Error?) { finalResults = processedResult self.exportButton?.isEnabled = true self.activityIndicator?.stopAnimating() } @IBAction func doneScanning(_ sender: UIBarButtonItem) { if isScanning { stopSession() } else { cancelScanning(sender) } self.exportButton?.isEnabled = false self.activityIndicator?.startAnimating() } @IBAction func cancelScanning(_ sender: UIBarButtonItem) { navigationController?.dismiss(animated: true) } // Export the USDZ output by specifying the `.parametric` export option. // Alternatively, `.mesh` exports a nonparametric file and `.all` // exports both in a single USDZ. @IBAction func exportResults(_ sender: UIButton) { let destinationFolderURL = FileManager.default.temporaryDirectory.appending(path: "Export") let destinationURL = destinationFolderURL.appending(path: "Room.usdz") let capturedRoomURL = destinationFolderURL.appending(path: "Room.json") do { try FileManager.default.createDirectory(at: destinationFolderURL, withIntermediateDirectories: true) let jsonEncoder = JSONEncoder() let jsonData = try jsonEncoder.encode(finalResults) try jsonData.write(to: capturedRoomURL) try finalResults?.export(to: destinationURL, exportOptions: .parametric) let activityVC = UIActivityViewController(activityItems: [destinationFolderURL], applicationActivities: nil) activityVC.modalPresentationStyle = .popover present(activityVC, animated: true, completion: nil) if let popOver = activityVC.popoverPresentationController { popOver.sourceView = self.exportButton } } catch { print("Error = \(error)") } } private func setActiveNavBar() { UIView.animate(withDuration: 1.0, animations: { self.cancelButton?.tintColor = .white self.doneButton?.tintColor = .white self.exportButton?.alpha = 0.0 }, completion: { complete in self.exportButton?.isHidden = true }) } private func setCompleteNavBar() { self.exportButton?.isHidden = false UIView.animate(withDuration: 1.0) { self.cancelButton?.tintColor = .systemBlue self.doneButton?.tintColor = .systemBlue self.exportButton?.alpha = 1.0 } } } The func captureView(shouldPresent roomDataForProcessing: CapturedRoomData, error: Error?) is mainly changed. I have confirmed in the debugger that the roomBuilder options are changed according to the buttons in the UI. Anyone who knows more about the behavior of this option, please give me an advice.
