I am using Lidar to measure the distance between the target point and the iPhone Pro. I am getting the correct distance only if I am greater than 70 cm away from the target point. I need that value to be accurate for distances below 70 cm as well. Is there any coding level issue or It's Lidar's limitations?

I have the following issue regarding running 2 AR service. I am trying to develop an app for my masters thesis. Case 1: I first scan the room using the roomplan api. Then I stop the roomplan api session and start the realitykit session. When the realitykit session starts, the camera is not showing anything but black screen. Case 2: When I had the issue with case one, I tried a seperate test app where I had 2 seperate screen for roomplan api and realitykit. There is no relation. but as soon as I introduced roomplan api, realitykit stopped working, having the same black screen as above. There might be any states that changed by the roomplan api, that's why realitykit is not able to access the camera. Let me know if you have any idea about it or any sample. I am using the following stack: Xcode - Latest; Swiftui; latest os in mac mini and iphone

Following along with video from here https://developer.apple.com/videos/play/wwdc2022/10127/?time=410 At 6:50 mark we set up setup previewVisualizer, but we're not actually shown the implementation of this type. I think it would be helpful as I am having a hard time showing white visualizing lines that appear when scanning.

Hello Community, I'm encountering an issue with the latest iOS 17 update, specifically related to RoomPlan version-2. In iOS 16, when using RoomPlan version-1, we were able to display stairs in our app. However, after upgrading to iOS 17 and implementing RoomPlan version-2, the stairs are no longer visible. Despite thorough investigation, I couldn't find any option within the code to show or hide stairs, or any other objects for that matter. It seems like a specific issue with the update rather than a coding error on our part. Has anyone else encountered a similar problem? If so, I would greatly appreciate any insights or solutions you might have. It's crucial for our app functionality to have stairs displayed accurately, and we're currently at a loss on how to address this issue. Thank you in advance for any assistance you can provide. Best regards

RoomPlan- Getting error for ceiling Height and floor Height from CapturedRoom. I am using RoomPlan version-2 Framework to scan houses. I need ceilingHeight and floorHeight. I am parsing the data of CapturedRoom successfully into Json and getting all keys and their value except "coreModel" of type: (RSFloorPlan) value. Does Apple support coreModel: RSFloorPlan yet? In "coreModel" key, there are some keys values of ceilingHeight and floorHeight. In the last I am getting encoded string as value of key "coreModel". CoreModel: qkgdxIDMaicOkpwW1I/h/V4C.........................7nCom3Lpu0CM= I will really appreciate your hard work.

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.

Hello, I used to be able to encode CapturedRoomData using JSONEncoder with the code below: // Encode CapturedRoomData func encodeRoomData(_ roomData: CapturedRoomData) -> Data? { print("#ECRD1 - Data: \(roomData)") do { let encodedRoom = try JSONEncoder().encode(roomData) print("#ECRD2 - Encoded: \(encodedRoom.description)") return encodedRoom } catch { print("#ECRD3 - Failed with error: \(error)") } return nil } A few weeks ago I noticed this approach is no longer working. The encoding fails and I get the following error printed: #ECRD3 - Failed with error: invalidValue(RoomPlan.CapturedRoomData, Swift.EncodingError.Context(codingPath: [], debugDescription: "Invalid data", underlyingError: nil)) Can anyone help me find the root of this problem? For reference, here’s what the printed CapturedRoomData looks like (with the keyframes omitted): #ECRD1 - Data: CapturedRoomData(keyframes: [...], coreAsset: <RSAsset: 0x283988bd0>, arFrameReferenceOriginTransform: simd_float4x4([[0.9995456, 0.0, 0.030147359, 0.0], [0.0, 1.0, 0.0, 0.0], [-0.030147359, 0.0, 0.9995456, 0.0], [0.38664898, 0.93699455, 0.38685757, 1.0]]))

start the session and took a scan everything looks perfect in the 3d while taking but after completing the scan, the 3d model that is presented on the screen is getting morphed within 4 sec gap . first it shows the correct one after 4 to 5 sec the usdz is getting morphed like all the straight walls are transforming into curved and if i have one walls getting some 2 to 3 walls with overlapping. not able to know why it is getting morphed like that. All I do was presenting the 3d model on the screen from the delegate method should Present - func captureView(shouldPresent roomDataForProcessing: CapturedRoomData, error: Error?) -> Bool { print("shouldPresentdelegate") if let error = error { print("shouldPresent error::",error) } return true } first it shows correct next in 4 to 5 sec its again reloads to another 3d form which is not correct at all . is there any reason behind this. can anyone please help me with this. your help is appreciated. Thankyou.

During scanning, I got this error and scanning process immediately quips without any output. I wonder what this error means and what caused it. Thanks.

Hello Everyone, I want to know whether roomplan gives us the complete info about the furniture sizing and alignment like how the object is being positioned in the room (wither forward/backward like that).

I'm trying to decipher this roomplan api data output. Dimensions: the simd3 is width and height and I think thickness in meters but the spacial information is not clear to me and I can't find any info on it. an insights on this? *** CAPTURED ROOM OBJECTS *** Walls: Identifier: 9F4BEEBB-990C-42F3-A0BC-912E1F770877 Dimensions: SIMD3(5.800479, 2.4299998, 0.0) Category: wall Transform: SIMD4(0.25821668, 0.0, 0.966087, 0.0) SIMD4(0.0, 1.0, 0.0, 0.0) SIMD4(-0.966087, 0.0, 0.2582167, 0.0) SIMD4(2.463065, -0.27346277, -0.5366996, 1.0) Identifier: A72544F5-068D-4F19-8FA4-60C1331003E3 Dimensions: SIMD3(2.28993, 2.4299998, 0.0) Category: wall Transform: SIMD4(0.966087, 0.0, -0.2582166, 0.0) SIMD4(0.0, 1.0, 0.0, 0.0) SIMD4(0.25821656, 0.0, 0.966087, 0.0) SIMD4(0.608039, -0.27346277, -3.0429342, 1.0)

It has been awhile since I looked at RoomPlan. I noticed when I was poking at the CapturedRoom, that there is binary data called coreModel... Does anyone know what this is? Is this related to ModelProvider? Thanks in advance.

I'm using RoomPlan to create a 2-d layout of a room. Because it's just a single room, I want to present it 'squared' up, see my picture First off, is there any options in the ARView that was used with the scan to sort of zero out the orientation so that it creates a room layout that is not on an angle? If not... Is there a well known mathematical formula to snap this to the closest 90 degrees? I tried just changing the rotation of each wall to snap to the nearest 90 degrees, but it wasn't quite good enough as they no longer joined together cleanly. Perhaps there's an algorithm for doing this while preserving the relative locations of everything?

Do I need an entitlement to use the ARWorldTrackingConfiguration and get that data in RoomPlan enhancements being done?

Is there any working sample code that demonstrates the 2nd multiroom approach, i.e., capture multiple rooms over more than one scan session using the ARWorldMap approach that's described in the WWDC presentation? I've tried working from the code snippets provided in the transcript but cannot get it working reliably enough.

Will Roomplan API be available for Vision OS? Currently its not available.

I am using the room plan api to implement the function of multiple space merging, but I found that after performing multiple space merging, the generated json would miss some of the newly added areas, but the usd file and plist file were complete.Does anyone have this problem? Look forward to official support this is my code: public func mergeScan(_ data:String,_ scanName:String,_ directoryName:String){ var capturedRoomArray: [CapturedRoom] = [] //解析主结构 let jsonURL = getRootURL().appending(path: "/\(directoryName)/\(scanName)/scan.json") guard let mainStructureRoom = try?loadCapturedRoom(from: jsonURL) else { return } capturedRoomArray.append(mainStructureRoom) // 添加子结构 if let subStructureRoom = try? loadCapturedRoom(from: data) { os_log("loadCapturedRoom string data success: %@", type: .error, String(describing: data)) capturedRoomArray.append(subStructureRoom) } os_log("merge scan capturedRoomArray: %@", type: .error, String(describing: capturedRoomArray.count)) //合并 Task { do { finalStructureResults = try await structureBuilder.capturedStructure(from: capturedRoomArray) }catch { print("Merging Error:\(error.localizedDescription)") return } do{ //保存 //导出json guard let finalStructureResults else { return } try exportJson(from: finalStructureResults, to: jsonURL) //导出usd let meshDestinationURL = jsonURL.deletingPathExtension().appendingPathExtension("usdz") //导出plist let metadataDestinationURL = jsonURL.deletingPathExtension().appendingPathExtension("plist") try finalStructureResults.export(to: meshDestinationURL, metadataURL: metadataDestinationURL, exportOptions: [.mesh]) } catch { print("Merge Error:\(error.localizedDescription)") return } } } func exportJson(from capturedStructure: CapturedStructure, to url: URL) throws { let encoder = JSONEncoder() encoder.outputFormatting = [.prettyPrinted, .sortedKeys] let data = try encoder.encode(capturedStructure) try data.write(to: url) } Note: Only json is missing the content of this or the next scan, usdz and plist are complete

I am scanning with ios17.2 on iphone12/ iPad with M1 attributes is always an empty array although I can see object categories and dimensions. They are not in the CapturedRoom object at the end or during the scan (printing the capturedRoom objects ), nor in the JSON export. what am I missing? Model provider can see them so it seems the data is in the unreadable "coreModel":"\/cCE2z0D7YOs5AV+590PFcMLD75UZjfuGUoGD8......"
