Hi, How can I check the value set for defaultSize in WindowGroup?

Hello, I'm here. I am posting this in the hope that you can give me some advice on what I would like to achieve. What I would like to achieve is to download the USDZ 3D model from the web server within the visionOS app and display it with the Shared Space volume (volumetric) size set to fit the downloaded USDZ model. Currently, after downloading USDZ and generating it as a Model Entity, Using openWindow, The Model Entity is created as a volumetric WindowGroup in the RealityViewContent of the RealityView using openWindow. The Model Entity generated by downloading USDZ is added to the RealityViewContent of the RealityView in the View called by openWindow. The USDZ downloaded by the above method appears in the volume on visionOS without any problems. However, the size of the USDZ model to be downloaded is not uniform, so it may not fit in the volume. I am trying to generate a WindowGroup with openWindow using Binding with the appropriate size value set to defaultSize, but I am not sure which property of ModelEntity can be set to the appropriate value for defaultSize. The attached image does not have the correct position and I would like to place the position down if possible. I would appreciate your advice on sizing and positioning the downloaded USDZ to fit in the volume. Incidentally, I tried a plane style window and found that it displayed a USDZ Model Entity that was much larger in scale compared to the volume, so I have decided not to support a plane style window. If there is any information on how to properly set the position and size of the USDZ files created by visionOS and RealityKit, I would appreciate it if you could also provide it. Best regards.

Feedback has been received, but when viewing Model3D, Entity, Model Entity, and AR Quick Look in the latest visionOS simulator, they appear dimmed. https://feedbackassistant.apple.com/feedback/13235272 image: https://ibb.co/GVLBKv7

Hi, I am currently developing a Full Space App. I have a question about how to implement the display of Entity or Model Entity in front of the user. I want to move the Entity or Model Entity to the user's front, not only at the initial display, but also when the user takes an action such as tapping. (Animation is not required.) I want to perform the initial placement process to the user's front when the reset button is tapped. Thanks.

I heard that iPhone 15 Pro or iPhone 15 Pro Max can shoot spatial video. However, I also know that the iPhone 15 Pro does not support spatial video shooting at first. When the iPhone 15 Pro becomes able to shoot spatial video, can the shot spatial video be played back on the visionOS simulator? When played back, is the video playback represented in three dimensions as a spatial video also performed in visionOS simulator? I would like to play back the spatial video shot with the iPhone 15 Pro using the VideoPlayerComponent of RealityKit. I am concerned that if the visionOS simulator does not support the operation verification of the shot spatial video, it will take a long time to verify it because I do not have an Apple Vision Pro device.

Hi, I implemented it as shown in the link below, but it does not animate. https://developer.apple.com/videos/play/wwdc2023/10080/?time=1220 The following message was displayed No bind target found for played animation. import SwiftUI import RealityKit struct ImmersiveView: View { var body: some View { RealityView { content in if let entity = try? await ModelEntity(named: "toy_biplane_idle") { let bounds = entity.model!.mesh.bounds.extents entity.components.set(CollisionComponent(shapes: [.generateBox(size: bounds)])) entity.components.set(HoverEffectComponent()) entity.components.set(InputTargetComponent()) if let toy = try? await ModelEntity(named: "toy_drummer_idle") { let orbit = OrbitAnimation( name:"orbit", duration: 30, axis:[0, 1, 0], startTransform: toy.transform, bindTarget: .transform, repeatMode: .repeat) if let animation = try? AnimationResource.generate(with: orbit) { toy.playAnimation(animation) } content.add(toy) } content.add(entity) } } } }

Hi, I have one question. How do I issue MagnifyGesture's onChange event in the visionOS simulator? I have tried various operations, but the onChange event does not work. https://developer.apple.com/videos/play/wwdc2023/10111/?time=994 @main struct WorldApp: App { @State private var currentStyle: ImmersionStyle = .mixed var body: some Scene { ImmersiveSpace(id: "solar") { SolarSystem() .simultaneousGesture(MagnifyGesture() .onChanged { value in let scale = value.magnification if scale > 5 { currentStyle = .progressive } else if scale > 10 { currentStyle = .full } else { currentStyle = .mixed } } ) } .immersionStyle(selection:$currentStyle, in: .mixed, .progressive, .full) } } Thanks.

Hi Scene Phases, but no event is issued when Alert is executed. Is this a known bug? https://developer.apple.com/videos/play/wwdc2023/10111/?time=784 In the following video, the center value is obtained, but a compile error occurs because the center is not found. https://developer.apple.com/videos/play/wwdc2023/10111/?time=861 GeometryReader3D { proxy in ZStack { Earth( earthConfiguration: model.solarEarth, satelliteConfiguration: [model.solarSatellite], moonConfiguration: model.solarMoon, showSun: true, sunAngle: model.solarSunAngle, animateUpdates: animateUpdates ) .onTapGesture { if let translation = proxy.transform(in: .immersiveSpace)?.translation { model.solarEarth.position = Point3D(translation) } } } } } Also, model.solarEarth.position is Point3D. This is not a simple Entity, is it? I'm quite confused because the whole code is fragmented and I'm not even sure if it works. I'm not even sure if it's a bug or not, so it's taking me a few days to a week to investigate and verify.

The source code for visionOS's WWDC23 session, Take SwiftUI to the next dimension, suddenly makes extensive use of GestureState. However, there is no sample code that shows the full extent of GestureState, nor is there any explanation of its use in the video. I cannot proceed with understanding unless you share information about this. https://developer.apple.com/videos/play/wwdc2023/10113/?time=969 URL of the capture of the part of the video where GestureState is used.

Hi, I watched the WWDC23 session video, "Create 3D models for Quick Look spatial experiences." https://developer.apple.com/videos/play/wwdc2023/10274/ In the video, I understood that the scale of models displayed using visionOS's AR Quick Look is determined by referencing the "metersPerUnit" value in USDZ files. I tried to find tools to set the "metersPerUnit" in 3D software or tools to view the "metersPerUnit" in USDZ files, but I couldn't find any. I believe adjusting the "metersPerUnit" in USDZ is crucial to achieve real-world scale when displaying models through visionOS's AR Quick Look. If anyone knows of apps or tools that can reference USDZ's "metersPerUnit" or 3D editor apps or tools that allow exporting with the "metersPerUnit" value properly reflected, I would greatly appreciate the information.

Hello, I am writing to you today to inquire about my application for the Apple Vision Pro Developer Kit. I submitted my application three times, but each time the application page displayed the text "%%USE_I18N_STRING_ERROR%%". After I submitted my application, the page I was redirected to said "We'll be back soon". I am not sure if my application was successful. I have not received any email confirmation. Would you be able to check the status of my application and let me know if there is anything else I need to do? Thank you for your time and consideration. Sincerely, Sadao Tokuyama https://twitter.com/tokufxug https://www.linkedin.com/in/sadao-tokuyama/

Hi, I have one question. The following shadow is shown on the simulator whether it is set in the ContentView of the Window in visionOS or not. https://developer.apple.com/documentation/SwiftUI/View/shadow(color:radius:x:y:) Even if I define the shadow in the ContentView and change the color, radius, x, and y, there is no change at all. I think that shadow is not enabled. Is this because it is a visionOS simulator? Best regards. Sadao Tokuyama https://1planet.co.jp/ https://twitter.com/tokufxug

Hi, If you write the sample code for the gesture in the following document and try to execute it, an error will occur. https://developer.apple.com/documentation/visionos/adding-3d-content-to-your-app Value of type '(@escaping (TapGesture.Value) -> Void) -> _EndedGesture' has no member 'targetedToAnyEntity' Is something missing? XCode 15.0 beta 2 (15A516b) visionOS 1.0 beta import SwiftUI import RealityKit import RealityKitContent struct SphereSecondView: View { @State var scale = false /*var tap: some Gesture { TapGesture() .onEnded { _ in print("Tap") scale.toggle() } }*/ var body: some View { RealityView {content in let model = ModelEntity( mesh: .generateSphere(radius: 0.1), materials: [SimpleMaterial(color: .yellow, isMetallic: true)]) content.add(model) } update: { content in if let model = content.entities.first { model.transform.scale = scale ? [2.0, 2.0, 2.0] : [1.0, 1.0, 1.0] } } .gesture(TapGesture().onEnded .targetedToAnyEntity() { _ in scale.toggle() }) } } #Preview{ SphereSecondView() } Best regards.

Hi, I have a question about Immersion Style. It is about progressive. I understand that by specifying progressive in Immersion, it is possible to mix mixed and full, but when is this used, for example, as in the WWDC23 movie where the person watching the movie on the screen gradually switches the room to space, or in the Digital Crown where the person is watching a movie on the screen and the room gradually changes to space? For example, when a person is watching a movie on the screen and the room gradually changes to space, as in the WWDC23 movie, or when the room gets darker and darker as the Digital Crown is adjusted, or when the room goes completely dark? Please let me know if you have a video, sample code, or explanation that shows an example of progression. By the way, is it possible to get the event of operating the Digital Crown from the application? Thanks. Sadao Tokuyama https://1planet.co.jp/ https://twitter.com/tokufxug

Hi, I run full immersive in the visionOS simulator and enable full immersive, but pass-through is still enabled. same behavior as mixed. Is there a bug in the visionOS simulator that prevents the pass-through with full immersive from being disabled? Thanks. Sadao Tokuyama https://1planet.co.jp/ https://twitter.com/tokufxug
