I want to know are depth map and RGB image are perfectly aligned(do both have the same principle point)? If yes then how the depth- map is created. The depth map on iphone12 has 256x192 resolution as opposed to an RGB image (1920x1440). I am interested in exact pixel-wise depth. Is it possible to get the raw depth map of 1920x1440 resolution ? How is the depth-map is created at 256 x 192 resolution? Behind the scenes does the pipeline captures it at 1920 x1440 resolution and then resize it to 256x192? I have so many questions as there are no intrinsic, extrinsic, and calibration data given regarding the lidar. I would greatly appreciate it if someone can explain the steps from a computer-vision perspective. Many Thanks

Hi, since iOS 15 I've repeatedly noticed the console warning »ARSessionDelegate is retaining X ARFrames. This can lead to future camera frames being dropped« even for rather simple projects using RealityKit and ARKit. Could someone from the ARKit team please elaborate what causes this warning and what can be done to avoid it? If I remember correctly I didn't even assign an ARSessionDelegate. Thank you!

Hi everyone! I am working on AR app and wanted to implement object occlusion because it removes drift pretty much from the object. This working great with RealityKit sample But I am unable to replicate such behaviour it with scenekit. Because scenekit does not offer object occlusion. Can we say scenekit is getting depricated, and we should re-write app in RealityKit (which is obviously a big task)?

Hi community, I have a pair of stereo images, one for each eye. How should I render it on visionOS? I know that for 3D videos, the AVPlayerViewController could display them in fullscreen mode. But I couldn't find any docs relating to 3D stereo images. I guess my question can be brought up in a more general way: Is there any method that we can render different content for each eye? This could also be helpful to someone who only has sight on one eye.

How do you force quit apps on the Vision Pro simulator? I've read online you can double press the digital crown on a real Vision Pro device but there is no such button on the simulator. So far I've tried Pressing the home button twice (⇧⌘H) Pressing the Siri button twice (⌥⇧⌘H) None of them works I'm on Xcode 15.0 beta 5 (15A5209g) & visionOS 1.0 beta 2 (21N5207e)

I’d like to use ARKit world tracking and display both the back camera feed and the front camera feeds, using the front feed as as a PIP. This would work great for an internet streaming use case. However, it’s impossible. As soon as ARKit is told to use one mode, the camera for the other side freezes/doesn’t work. This page also says you have to pick one camera to show: https://developer.apple.com/documentation/arkit/arkit_in_ios/choosing_which_camera_feed_to_augment?language=objc A question to the developers: why is this limitation in-place? Are there any work-arounds for the use case of ARKit world tracking + displaying the back camera feed + displaying the front camera feed as an overlay? It’s possible to do this with plain camera initialization without ARKit. (There’s an official example.) With ARKit, it no longer works. It’s strange that I cannot access the front feed via one of the other frameworks, but I guess that ARKit blocks that.

I've been using the MacOS XCode Reality Composer to export interactive .reality files that can be hosted on the web and linked to, triggering QuickLook to open the interactive AR experience. That works really well. I've just downloaded XCode 15 Beta which ships with the new Reality Composer Pro and I can't see a way to export to .reality files anymore. It seems that this is only for building apps that ship as native iOS etc apps, rather than that can be viewed in QuickLook. Am I missing something, or is it no longer possible to export .reality files? Thanks.

Reality Composer is no longer available in XCode 15 Release. Is this intended or will be available in later releases? Do I need to revert to Xcode15 Beta8 to get Reality Composer?

What will be the pros and cons if unreal engine is used in apple vision pro? What are the issues that unreal will face in future on apple vision pro? What will be the specifications required for unreal to work on vision pro?

How do we author a Reality File like the ones under Examples with animations at https://developer.apple.com/augmented-reality/quick-look/ ?? For example, "The Hab" : https://developer.apple.com/augmented-reality/quick-look/models/hab/hab_en.reality Tapping on various buttons in this experience triggers various complex animations. I don't see any way to accomplish this in Reality Composer. And I don't see any way to export/compile to a "reality file" from within Xcode. How can I use multiple animations within a single GLTF file? How can I set up multiple "tap target" on a single object, where each one triggers a different action? How do we author something similar? What tools do we use? Thanks

I want to open a view in my App that contains a Model3D view and I want that object to rotate continuously around the Y axis while it is visible. Is it possible to animate the rotation of a Model3D view? I've tried this code, but the object just sits there and doesn't rotate. import RealityKit import RealityKitContent import SwiftUI struct QuantumComputerArea: View { @State var degreesRotating = 0.0 var body: some View { VStack { Model3D(named: "quantumComputer") { phase in switch phase { case .empty: ProgressView() case let .failure(error): Text(error.localizedDescription) case let .success(model): model .resizable() .scaledToFit() .offset(x: -75, y: 0) .rotation3DEffect(.degrees(degreesRotating), axis: (x: 0, y: 1, z: 0)) @unknown default: fatalError() } //phase } //Model3D .onAppear { withAnimation(Animation.linear(duration: 10).repeatForever(autoreverses: false)) { degreesRotating = 360 } } } //VStack } //View } //View I'm probably missing something simple but if anyone has any suggestions (including use a RealityView) I'd be grateful for the advice.

I tried to show spatial photo on my application by swiftUI's Image but it just show flat version of it even I Use Vision Pro, so, how can I show spatial photo to users, does there any options for this?

We are building an AR experience for deployment on iphones. We are using Unity but it looks as if Reality Composer Pro has better features for spatial audio. I am not sure if Reality Composer Pro can only be used for Vision Pro or can it also be used for deployment on Iphone or ipad.

Is there any way to detect if an entity is being looked at in a RealityView. I know it is possible to add a "HoverEffectComponent()" which will highlight the entity a little when you gaze on it, but there doesn't seem to be any way to call a function from this. There is also no GazeGesture or anything similar.

I am working with MeshAnchors, and I am having troubles getting to the classification of the triangles/faces. This post references the MeshAnchor.Geometry, and that struct does have a property named "classifications", but it is of type GeometrySource. I cannot find any classification information in GeometrySource. Am I missing something there? I think I am looking for something of type MeshAnchor.MeshClassification, but I cannot find any structs with this as a property.

Hello Community, I'm encountering an issue with the latest iOS 17 update, specifically related to RoomPlan version-2. In iOS 16, when using RoomPlan version-1, we were able to display stairs in our app. However, after upgrading to iOS 17 and implementing RoomPlan version-2, the stairs are no longer visible. Despite thorough investigation, I couldn't find any option within the code to show or hide stairs, or any other objects for that matter. It seems like a specific issue with the update rather than a coding error on our part. Has anyone else encountered a similar problem? If so, I would greatly appreciate any insights or solutions you might have. It's crucial for our app functionality to have stairs displayed accurately, and we're currently at a loss on how to address this issue. Thank you in advance for any assistance you can provide. Best regards

Rendering the scene onto a RenderTarget with twice the resolution of the Drawable, and then downsampling to the Drawable, causes the image to appear distorted. Modifications were made on the Xcode VisionOS template Foveation should be enabled by default struct ContentStageConfiguration: CompositorLayerConfiguration { func makeConfiguration(capabilities: LayerRenderer.Capabilities, configuration: inout LayerRenderer.Configuration) { configuration.depthFormat = .depth32Float configuration.colorFormat = .bgra8Unorm_srgb let foveationEnabled = capabilities.supportsFoveation configuration.isFoveationEnabled = foveationEnabled let options: LayerRenderer.Capabilities.SupportedLayoutsOptions = foveationEnabled ?

I am planning to build a VisionOS app and need to get access to the persona (avatar). I have not found any information regarding integration possibilities in the docs. Does anyone know if and how I can access the user's persona? Other applications like Zoom and Teams for VisionOS use the persona, so I think it is basically possible. Apparently (if it's not fake) there is also a chess game with integrated persona: https://www.youtube.com/watch?v=mMzK8C3t14I Any help is very welcome, thanks.

I made an animation in Blender using geometry nodes that I exported to USDC file (then I used Reality Converter to convert to USDZ) and I can see the animation when viewing from the finder but does not play after importing to RCP. Any idea how I can play the animation? Or can the animation be accessed through Xcode? Thanks!

I’ve submitted the following feedback: FB13820942 (List Outline View Not Using Accent Color on Disclosure Caret for visionOS) I’d appreciate help on this to see if I’m doing something wrong or indeed it’s the way visionOS currently works and it’s a suggested feedback.
