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......"

how can we change the image quality, size, camera and cadence used during RoomPlan's scanning. We are getting the images from RoomCaptureSession.

Error: RoomCaptureSession.CaptureError.exceedSceneSizeLimit Apple Documentation Explanation: An error that indicates when the scene size grows past the framework’s limitations. Issue: This error is popping up in my iPhone 14 Pro (128 GB) after a few roomplan scans are done. This error shows up even if the room size is small. It occurs immediately after I start the RoomCaptureSession after the relocalisation of previous AR session (in world tracking configuration). I am having trouble understanding exactly why this error shows and how to debug/solve it. Does anyone have any idea on how to approach to this issue?

Is there a way to handle Roomplan ExceededSceneSizelimitError. in documentation also there is nothing . For me after taking just small small scans about 5 to 6 after the 7 th scan getting this error . only killing the app and restarting is working, if i come to back page and again go to start newscan also it is not working

We scan the room using the RoomPlan API, and after the scan, we obtain objects with a white color along with shadows and shading. However, upon updating the color of these objects, we experience a loss of shadows and shading. RoomPlan scan After Update

Has anyone had success with RoomPlan to scan an entire home? We use floor plan scanning technology for our real estate business and RoomPlan is great as it has instant results but we need the entire home with a staircase for total square footage purposes. Thanks in advance, Luke

Hi Is this possible to have RoomCaptureSession and ARSession together, as we need feature points

Hey guys, I hope you are all doing well! I am really stuck on a problem and I need help here. I am new to Swift but I need to use Swift to complete a project. I am trying to use this code https://github.com/jmousseau/RoomObjectReplicatorDemo/blob/main/RoomObjectReplicatorDemo/ViewController.swift with the RoomObjectReplicator library https://github.com/jmousseau/RoomObjectReplicator. However, the issue is that my app is currently using SwiftUI and not UIKit. Furthermore, I have ContentView and ARViewContainer. How can I implement the code but use ContentView and ARViewContainer along with SwiftUI? Thanks in advance!

A case occured where the Structure Builder is crashing with EXC_BAD_ACCESS and the error cannot be handled without the app crashing. I have two minimalistic models, one even reduced to the minimum of the "coreModel" itself. (See attachment) Each model alone in the StructureBuilder works fine. Using both causes the crash. Has anyone found a way to handle this error without the app crashing? override func viewDidLoad() { super.viewDidLoad() let capturedRooms: [CapturedRoom] = [ loadCapturedRoom(fileName: "appleModel1"), loadCapturedRoom(fileName: "appleModel2") ] buildStructure(capturedRooms) } func buildStructure(_ capturedRooms: [CapturedRoom]) { let structureBuilder = StructureBuilder(options: []) Task { print("----- START BUILDING STRUCTURE -----") do { let capturedStructure = try await structureBuilder.capturedStructure(from: capturedRooms) } catch { print("----- FAILED BUILDING STRUCTURE -----") } // Crashing with: EXC_BAD_ACCESS // This part will never be reached print("----- FINISH BUILDING STRUCTURE -----") } } func loadCapturedRoom(fileName: String) -> CapturedRoom { do { guard let jsonFileURL = Bundle.main.url(forResource: fileName, withExtension: "json") else { fatalError("JSON file not found.") } let data = try Data(contentsOf: jsonFileURL) return try JSONDecoder().decode(CapturedRoom.self, from: data) } catch { fatalError(error.localizedDescription) } } appleModel1.json appleModel2.json

when i start roomplan scanner,there reminder "Move device to start",and other reminder, now i use roomplan in china, i want use custom remider in my apps, how should i do?

Hi, I want to capture the real world colors and textures of the objects into RoomPlan scans. and export the model as USDZ. Is there a way to achieve this?

I am currently working on a project involving the merging of multiple scans into a single structure using Room plan json file. I am facing an issue and would greatly appreciate your assistance in resolving it. The problem I am encountering is as follows: "Cannot process multiFloorPlan: Invalid room location in structure" Captured room json file paths: [https://mimesisfbs.s3.ap-south-1.amazonaws.com/project_3dfile_json/2088a003-5712-4e9f-91eb-601b145ca98e-project_3dfile_json_file.json) [https://mimesisfbs.s3.ap-south-1.amazonaws.com/project_3dfile_json/10ccd0d9-7843-41bd-a021-a57781231059-project_3dfile_json_file.json) We are using same code as in example.

Hi all. Can anyone show the code for multiroom on swiftUI? And another question, is it possible to change the parameters (dimensions) of walls, doors, windows in an already scanned room by entering real dimensions from a laser tape measure? Because the scanned object has dimensional errors of up to 3 cm. Thanks.

I'm looking for the full sample code from WWDC23 session https://developer.apple.com/videos/play/wwdc2023/10192
