No. If you watch the WWDC demo you will see how the window over the sink is an arch style but the scan uses a bounding rectangle to define it. It still does a pretty decent job and if you remember from Calculus, you can still get the area under a curve if your rectangles are small enough. :-)

Please note that my request above is for RoomObjects only. The Surface detection is perfect as is for Door, Window, Wall and Opening.

I was able to get it to work using a fresh ARKit project from Xcode 14 Beta 2 and what was presented at WWDC like so: import UIKit import RealityKit import RoomPlan import ARKit class ViewController: UIViewController {     var roomCaptureSessionConfig: RoomCaptureSession.Configuration = RoomCaptureSession.Configuration()     @IBOutlet var arView: ARView! //    var previewVisualizer: Visualizer!     lazy var captureSession: RoomCaptureSession = {         let captureSession = RoomCaptureSession()         arView.session = captureSession.arSession         return captureSession     }()         override func viewDidLoad() {         super.viewDidLoad()         captureSession.delegate = self     }     override func viewDidAppear(_ animated: Bool) {         super.viewDidAppear(animated)         captureSession.run(configuration: roomCaptureSessionConfig)     } } extension ViewController: RoomCaptureSessionDelegate {     func captureSession(_ session: RoomCaptureSession,                         didUpdate room: CapturedRoom) {         print(room) //        previewVisualizer.update(model: room)     }     func captureSession(_ session: RoomCaptureSession,                         didProvide instruction: RoomCaptureSession.Instruction) {         print(instruction)   //    previewVisualizer.provide(instruction)     } } That will really fill up your console pretty quickly and turn your phone into a nice hand warmer if you're not careful. :-)

I had this same reaction. It's at 6:50 into the RoomPlan demo presentation. When I got the compiler error for Visualizer I was thinking I missed an import, then I played the video a few times and barely caught the 'custom class example' comment.

I'm not sure if you are aware but USD is an Open Source standard with a C++ library and Python wrappers. Here is the tool to install: https://download.developer.apple.com/WWDC_2022/USDPython_0.66/USDPython0.66.zip Here are the Open Source tools to work with the file format: https://graphics.pixar.com/usd/release/toolset.html# Here is the GitHub page Pixar shares the source code for this USD toolset and file format code details: https://github.com/PixarAnimationStudios/USD

You can download the demo app presented at WWDC 2022 from this link: https://developer.apple.com/documentation/roomplan/create_a_3d_model_of_an_interior_room_by_guiding_the_user_through_an_ar_experience/ There is a blue download button at the top of the docs. You will also need Xcode 14 beta, Mac OS 12.4 (min. OS required by Xcode) and a PHYSICAL iPhone/iPad with a LiDAR sensor. So an iPhone 12/13 Pro or the latest iPad Pro models that have LiDAR.

I get this error as well but only when I try to do an 'incremental' by clicking the 'RESUME' button in Xcode to run a PreviewProvider SwiftUI View. Hopefully this gets fixed soon as this used to work and is very valuable when doing SwiftUI dev work.
