We are attempting to update the texture on a node. The code below works correctly when we use a color, but it encounters issues when we attempt to use an image. The image is available in the bundle, and it image correctly in other parts of our application. This texture is being applied to both the floor and the wall. Please assist us with this issue." for obj in Floor_grp[0].childNodes { let node = obj.flattenedClone() node.transform = obj.transform let imageMaterial = SCNMaterial() node.geometry?.materials = [imageMaterial] node.geometry?.firstMaterial?.diffuse.contents = UIColor.brown obj.removeFromParentNode() Floor_grp[0].addChildNode(node) }

We are using the RoomPlan API to capture data, which is stored in the 'CapturedRoom' variable in our code (referred to as 'finalResult'). We then attempt to save a USDZ file in the file manager. Sometimes it works, but other times, we encounter issues like the one below Coding Error: in _IsValidPathForCreatingPrim at line 3338 of usd/stage.cpp -- Path must be an absolute path: <> cannotCreateNode(path: "/9EE71ED0F8D6415496A7B9F0C3671DB0321") This is that code we are using for shaving CapturedRoom data func saveFileLocal() { if let finalResult { let fm = FileManager.default let documentsURL = fm.urls(for: .documentDirectory, in: .userDomainMask).first! //let documentsURL = URL.documentsDirectory let fileName = "\(UUID().uuidString).usdz" let fileURL = documentsURL.appendingPathComponent(fileName) do { try finalResult.export(to: fileURL) } catch { print(error) } } } Please help us.

I'm just curious if anybody knows if under the hood RoomPlan is applying any sort of sorting to the CapturedRoom.walls array. Like does RoomPlan try to sort the walls so they complete a loop? Or are walls simply appended to the back of the array as they are detected?

We are trying to save usdz file in file manager some time its saved but some time we are getting the error. Like: path.absoluteURL file:///var/mobile/Containers/Data/Application/6D14A430-47B4-45F2-9D0D-6C31588A6A03/Documents/2896837C-C7E0-4FA8-BFE2-21A59B26D801.usdz Warning: in SdfPath at line 151 of sdf/path.cpp -- Ill-formed SdfPath &lt;/2896837CC7E04FA8BFE221A59B26D801&gt;: syntax error Coding Error: in _IsValidPathForCreatingPrim at line 3338 of usd/stage.cpp -- Path must be an absolute path: &lt;&gt; cannotCreateNode(path: "/2896837CC7E04FA8BFE221A59B26D801") func saveFileLocal() { if let finalResult { let fm = FileManager.default var path = fm.urls(for: .documentDirectory, in: .userDomainMask).first! let fileName = "(UUID().uuidString).usdz" path.appendPathComponent(fileName) do { try finalResult.export(to: path.absoluteURL) } catch{ print(error) } } } func removeFiles() { var filePath = "" let fm = FileManager.default let path = fm.urls(for: .documentDirectory, in: .userDomainMask).first! do{ let content = try fm.contentsOfDirectory(atPath: path.path) for c in content{ filePath = path.appendingPathComponent(c).absoluteString if let url = URL(string: filePath){ try fm.removeItem(at: url) } } } catch{ print(error) } }

I am using the RoomPlanExampleApp to export a USDZ. When I open the USDZ on Reality Converter, I get this error Invalid Structure in USDZ file The root layer of the package must be a usdc file and must not include any external dependencies that participate in stage composition.

Is there a way to combine roomplan api with arkit+metalkit to get both pointcloud .ply output and roomplan 3d room model .usdz?

We want to be able to use our own prompt / coaching for RoomPlan I see that I can override the following method to see the RoomCaptureSession.Instruction and then add or our UI to coach the customer func captureSession(_ session: RoomCaptureSession, didProvide instruction: RoomCaptureSession.Instruction) { Logger.log(.info, category: .roomplan, message: "RoomCaptureSession.Instruction(\(instruction))") // Show coaching prompts } However, I don't know how to remove the coaching UI provided by the OS. If I disable coaching sessionConfig = RoomCaptureSession.Configuration() sessionConfig.isCoachingEnabled = false Then the callback above was not being called. I really want a willProvide method that I can return 'false' to say that I want to give my own UI instead of the UI provided by RoomPlan. Is there a way to provide my own ui for these RoomCaptureSession.Instructions? Thanks in advance

I need to generate a thumbnail from CapturedRoom, that is either a static frame of the PIP thumbnail that we see in the result after scanning. Ideally an image, but I could also use a simplified OBJ if that's a possibility. From documentation it looks like the only option is to export as USDZ. Is there a way to generate a static image file after room scan is processed? try finalResults?.export(to: destinationURL, exportOptions: .mesh)

I'm unable to debug on iPhone 12 running iOS 17 beta 3 via network. I'm running Xcode 15 beta 6 Device shows in devices and simulators and I can debug when connected with cable. However the "Connect Via Network" option is frayed out, oddly however the checkbox is ticked I'm developing a app using RoomPlan so network connectivity is a must for debugging Anyone else encountered this and know how to get around this problem Other devices running iOS 16 connect via network just fine

I'm trying to merge room with WorldMap: but my screen goes black when doing a scan, First: i load world map arWorldTrackingConfig.initialWorldMap = worldMap //arWorldTrackingConfig.planeDetection = [.horizontal, .vertical] arSession.run(arWorldTrackingConfig) if #available(iOS 17.0, *) { roomCaptureView = RoomCaptureView(frame: view.bounds, arSession: arSession) } else{ roomCaptureView = RoomCaptureView(frame: view.bounds) } roomCaptureView = RoomCaptureView(frame: view.bounds) roomCaptureView.captureSession.delegate = self roomCaptureView.delegate = self view.insertSubview(roomCaptureView, at: 0) and save when scan done: roomCaptureView?.captureSession.arSession.getCurrentWorldMap { worldMapData, error in if let error = error { return } if let worldMap = worldMapData { let fileURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("worldMapData") do { let data = try NSKeyedArchiver.archivedData(withRootObject: worldMap, requiringSecureCoding: true) try data.write(to: fileURL) } catch { print("error ARWorldMap: \(error.localizedDescription)") } } } the first scan is fine, but the next time, when the worldMap is saved and loaded, my screen goes black, does anyone have a solution or sample code?? -thank-

I am trying to find the size limitations for RoomPlan. Originally I was planning to get this data from the exceedSceneSizeLimit error. But it appears that errors are only given to the delegate once the captureSession is ended and it provides the final capture data to the delegate.

Is there a method to extract the iphone position and orientation? Or to get the trajectory of the iphone during the room scan?

Hi, I'm trying to implement the RoomPlan, could you tell me pls, which methods I can use to manipulate with resulted rendered room model: i.e. chenge the wall color by click etc. It can looks laughly but I didn't use this API before. If it doesnt have such functions please recoomend the api which I can use to manipulte scan results for such case: selecting a wall and change its color or marking it with some symbols which should be rendered on it. Thx

Is there an easy way from API to get surface area measurements?

I am building an app that uses the RoomPlan API, but I am hoping to change the UI, is it possible to, for instance, change the color of the lines that are displayed? Also, there only appears to be a way to turn off the live model, not translate it around the screen. Is it possible to do either of these things in IOS 17's RoomPlan?

Hey team, I was looking at the new Sections data in RoomPlan. It's really awesome! However, it looks like the polygons data is being stored as a SIMD2 instead of SIMD3. Is the data being cast incorrectly? (I see the Y axis seems to match the ground level). If so, would you mind fixing this bug? It would be great to see this data!

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.
