Anybody try hand tracking provider in 2.0? I'm getting them in 11ms interval, as advertised, but they are duplicate. Here's a print of the timestamps. Problematic for me because I am tracking the last 5 position for a calculation and expect them to be unique. Can't find docs on this anywhere. I understand it's not truly 90 updates a second but predicted pose, however I expected the updates to include predicted poses.

I am using ArKit to create an augmented reality application in Unity. Following the addition of an object reference object Because it tracks the object in front of it slowly and inaccurately, the application does not update the screen quickly. How can I track objects more quickly?

it is my code let portal = Entity() portal.components[ModelComponent.self] = .init(mesh: .generatePlane(width: Float(size.width), height: Float(size.height), cornerRadius: 0.02), materials: [PortalMaterial()]) portal.components[PortalComponent.self] = .init(target: world) portal.components[PortalComponent.self]?.clippingPlane = .init(position: SIMD3(x: 0, y: 0, z: 0), normal: SIMD3(x: 0, y: 0, z: 0)) portal.components.set(HoverEffectComponent()) I added RealityView to multiple HStacks and implemented the portal effect. I found that the portal effect would cause confusion in the rendering level on some machines, as shown in the figure

I have an app on the App Store for many years enabling users to post text into clouds in augmented reality. Yet last week abruptly upon installing the app on the iPhone the screen started going totally dark and a list of little comprehensible logs came up of the kind: ARSCNCompositor <0x300ad0e00>: ARSCNCompositor (0, 0) initialization failed. Matting is not set up properly. many times, then RWorldTrackingTechnique <0x106235180>: Unable to update pose [PredictorFailure] for timestamp 870.392108 ARWorldTrackingTechnique <0x106235180>: Unable to predict pose [1] for timestamp 870.392108 again several times and then: ARWorldTrackingTechnique <0x106235180>: SLAM error callback: Error Domain=Slam Error Code=7 "Non fatal error occurred due to significant drop in a IMU data" UserInfo={NSDescription=Non fatal error occurred due to significant drop in a IMU data, NSLocalizedFailureReason=SlamEngineNodeGroup Failure: IMU issue: gyro data stream verification failed [Significant data drop]. Failed on timestamp: 870.413247, Last known timestamp: 865.350198, Delta: 5.063049, System timestamp: 870.415781, Delta between system and frame: 0.002534. } and then again the pose issues several times. I hoped the new beta version would have solved the issue, but it was not the case. Unfortunately I do not know if that depends on the beta version or some other issue, given the app may be not installed on the Mac simulator.

Hey Everyone, this is like my first post here in the apple forum. I need your help to understand better Reality Kit and file exports, but let me explain. I'm trying to create a little 3D Object editor, and it looks like to work pretty well using RealityViews and managing materials on the Entity. I'm currently working with all the Beta Apis and I would like to export my entity into an .usdz or a .obj file. I've found a method that allows me to create a .Reality File let path = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0].appendingPathComponent("model.reality") try await self.appState.parentEntity.write(to: path) but I now I don't know how to convert it into a .usdz or a .obj file, or otherwise any standard 3d format. Do you have any idea on how could I do? Thankyou so much! Have a nice day ^^

We can use the CreateML App to build object tracking model in Xcode 16, but is it possible to use CreateML framework as well? No documentation of Create ML object tracking is found yet. The latest documentation I can found is Xcode 15. https://developer.apple.com/documentation/CreateML?changes=latest_minor Really apricated the new feature of object tracking, thank you Apple Team.

I am using Model3D to display an RCP scene/model in my UI. How can I get to the entities so I can set material properties to adjust the appearance? I looked at interfaces for Model3D and ResolvedModel3D and could not find a way to get access to the RCP scene or RealityKit entity.

Does visionOS 2 still prompt the user with a permission alert when a full immersive space is presented? In visionOS 1, the first time an app presented an immersive space, the user was prompted with an alert to grant permission. openImmersiveSpace would return an error code if the user opted not to grant permission. In visionOS 1, it was important to handle this case correctly. In visionOS 1, the Settings > Developer menu had an option to reset the immersive user's space permission prompting state so developers could test this interaction flow. In visionOS 2, I no longer see the full immersive space permissions alert. I can't remember if I saw it once, the first time visionOS 2.0 beta was installed, or if I never saw it at all. The Settings > Developer menu no longer has an option to reset the permission prompting state. I can't find any way to test the interaction flow in my app to make sure that it will work correctly for users. Does visionOS 2 no longer ask for full immersive space permission at all? I can't find this change documented anywhere. If visionOS 2 does prompt the user for permission, is there any way to reproduce and test this interaction flow so I can make sure my app handles it correctly? Thanks for taking the time to answer this question.
