I noticed that tracking moving images is super slow on visionOS. Although the anchor update closure is called multiple times per second, the anchor's transform seems to be updated only once in a while. Another issue might be that the SwiftUI isn't updating more often. On iOS, image tracking is pretty smooth. Is there a way to speed this up somehow on visionOS, too?

Hello, I’m trying to move my app into vision OS, my app is used for pilot to study the airplane system, is a 3d airplane cockpit build with scene kit and I use sprite scene to animate the cockpit instruments . Scenekit allow to apply as material a sprite scene , so I could animate easy all the different instruments and indication there, but I can’t find this option on reality compose pro , is this possible? any suggestions I can look into to animate and simulate instruments.

I am having problems getting button input from an Xbox game controller. I have the visionOS 2 beta on my Apple Vision Pro, and I am trying to use an Xbox game controller with a RealityView following the instructions from the WWDC session Explore game input in visionOS. The notification about a game controller is picking up the game controller, finds GCInputButtonA, and I am setting closures for touchedChangedHandler, pressedChangedHandler, and valueChangedHandler that just print an os_log statement. buttonA.valueChangedHandler = { button, value, pressed in os_log("Got valueChangedHandler") } At the end of RealityView, I have the modifier RealityView { content in // stuff } .handlesGameControllerEvents(matching: .gamepad) But I am never seeing the log message appear in the console when I press the 'A' button (or any other button). Any ideas what I might be doing wrong? The Xbox controller is pretty old. Settings is reporting it as version 9.0.3

Hi everyone, I'm working with Core ML for object tracking and have successfully trained a couple of models. However, when I try to use the reference object file in the object tracking sample code from the WWDC video, it doesn't work. I'm training the model on a single-color plastic spherical object. Could this be the reason for the issue? I also attempted to use USDZ 3D assets that resemble the real object. Do these need to be trained with the Object Capture app to work properly? Speaking of the Object Capture app, my experience hasn't been great. When I scanned my spherical object, the result was far from a sphere—it looked more like a mushy dough. Any insights or suggestions would be greatly appreciated!

Hi, With this code on iPad Pro (11-inch) (4th generation), when capturing in area mode and pressing the "Next" Button, an overlay with a white dot in the center appears. Everything else is blurred out and the app is stuck. It does seem to work well on iPhones though. Thanks!

Does anyone have code for realistic shaders for the Sun and Earth for a cosmology app in visionOS? Thanks

Hi, I am trying to train an object tracking model on MacBook Air with a M2 silicon. The .usdz file used to train is captured by iPhone 14 pro. However the training process takes too much time. it stay at 0.0% for about an hour and a half. I wonder if there is any other methods to generate reference objects.

Hi fellows, I am developing a conceptual prototype to explore how Apple Vision Pro can be applied in Real Estate selling. But I encounter an problem and to consult with the developer community. When rendering a massive 3D entity, sometimes it work fine but sometimes my Vision Pro device automatically reboot (all the running apps are shutdown and then Apple logo appears to reboot) while running the app. I have a 1:1 3D entity imported into the Reality Composer Pro, and I managed to develop a simple rendering Vision Pro app. It works great after I finally made it work and see the 1:1 building in front of me. You can see the full demo video for details: https://www.icloud.com/iclouddrive/0d5QA-sYSehmLF9rEMXsCUyDg#REPtt02_Demo_v1.1 But sometimes when rendering the 1:1 building, my Vision Pro device suddenly reboot. So far I have no clues on its root cause. It might be caused by the not-enough-memory or for safety concern? (since the 3D entity is big and might block a big area of the view) Can any one or even an official provide some guidance here and identify the root cause? Thx much!

We deliver an SDK that enables rich spatial computing experiences. We want to enable our customers to develop apps using Swift or RealityComposer Pro. Composer allows the creation of custom components from the add components button in the inspector panel. These source files are dropped into the RealityComposer package and directory. We would like to be able to have our customers import our SDK components into their applications RealityComposer package and have our components be visible to be applied by our customer into their scene compositions. How can we achieve this? We believe this will lead to a risk ecosystem components extensions for RealityComposer Pro.

I learned Sharplay from the WWDC video. I understand the creation of seats, but I can't learn some of the following contents well, so I hope you can help me. The content is as follows: I have set up the seats. struct TeamSelectionTemplate: SpatialTemplate { let elements: [any SpatialTemplateElement] = [ .seat(position: .app.offsetBy(x: 0, z: 4)), .seat(position: .app.offsetBy(x: 1, z: 4)), .seat(position: .app.offsetBy(x: -1, z: 4)), .seat(position: .app.offsetBy(x: 2, z: 4)), .seat(position: .app.offsetBy(x: -2, z: 4)), ] } It was mentioned in one of my previous posts: "I hope you can give me a SharePlay Button. After pressing it, it will assign all users in Facetime to a seat with elements quantified in TeamSe lectionTemplate.", and someone replied to me and asked me to try systemCoordinator.configuration.spatialTemplatePreference = .custom (TeamSelectionTemplate()), however, Xcode error Cannot find 'systemCoordinator' in scope How to solve it? Thank you!

Hello, I have rendered an usdz File using sceneKit's .write() method on the displayed scene. Once I load it on another RealityKit's ARView using the .nonAR mode of the camera, I am trying to use the view's raycast(from:,allowing:,alignment:) method, to get the coordinates on the model. I have applied the collisionComponents when loading the model using the .generateCollisionShapes() function to be able to interact with the modelEntity. However, the raycast result returns nothing. Is there something I am missing for it to work? Thanks!

Hello, We are wondering how and if we can save/render the view that a PerspectiveCamera sees in VisionOS. Ideally, the goal is to use a PerspectiveCamera in a Mixed Immersive space and render out what it sees. We don't see any methods exposed for rendering the view. We would truly appreciate any advice on this! Thank you.

Hello everyone! I'm planning to buy an Apple Vision Pro (for replacing a Varjo XR-3) I want to use it for a professional project, and I want to know if it can fit our need. I want to develop a program on the Vision Pro for playing some live streaming videos from our local network cameras. (using RTSP) Is this possible to get and play more than one live stream video. One of those videos come from a stereo camera, streaming a SideBySide 3d stereo video. Is this possible to have a classic 2d video in one ultra-wide virtual screen and another one virtual screen displaying a 3D video with depth simultaneously? Thank you everyone in advance. Regard's.

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.

When I wanted to call the Reality Composer Pro scene containing Object Tracking, I tried the following code: RealityView { content in if let model = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(model) } } Obviously, this is wrong. We need to add some configurations that can enable Object Tracking to Reality View. What do we need to add? Note:I have seen https://developer.apple.com/videos/play/wwdc2024/10101/, but I don't know much about it.

As the question suggests, I would like to use environmental awareness and item placement functions in Unity. Does have any related example projects?

The project was developed using Unity, and the requirement is to place a virtual model in the real world. When the user leaves the environment or the machine is turned off and then on again, the virtual model is still in its original real position. I found that the worldtracking function of Arkit is useful, but I don't know how to use it in Unity. Is that have any related example projects?

Hi, Object Capture's original sample code was released last year, and this year there was a talk about adding area mode to it. The talk links to the old Object Capture code - when can I expect to have the new one with area mode, and is there anything I can help you with to have it published faster? Thanks!

I am trying to make the immersive version of AVplayerViewController bigger, but I can't find any information on how I can go about it. It seems that if I wanted to change immersive video viewing experience, only thing I can do is using VideoMaterial and put it on ModelEntity with .generatePlane. is there a way to change video size on immersive mode for AVplayerViewController?

hello i wanna play mp4 file in VideoMaterial avPlayer. so first i make to use reality composer pro. I created matterial using the sphere provided by default in Reality Composer Pro and exported it to usdz. and when i play mp4 file in sphere matterial, it's good play But i wanna custom created matterial (ex. shaper3d create 3d modeling) not good play. i make custom created matterial - it's curved matterial curved matterial in shaper3d and exported it to usdz. curved matterial in Reality Composer Pro Scene and exported it to usdz. when i play mp4 file in curved matterial, it's not good play -> not adjust screen play How can I adjust and display the video in a custom usda file?
