The new Mac virtual display feature on visionOS 2 offers a curved/panoramic window. I was wondering if this is simply a property that can be applied to a window, or if it involves an immersive mode or SceneKit/RealityKit?

Hi, I'm very new to 3D and am currently porting a SwiftUI iOS app to visionOS 2.0. I saw WWDC24 feature Blender in multiple spatial videos, and have begun integrating Blender models and animations into my VisionOS app (I would also like to integrate skeletons and programmatic rigging, more on that later). I'm wondering if there are “Best Practices” for this workflow - from Blender to USD to RCP 2.0 to visionOS 2 in Xcode. I’ve cobbled together the following that has some obvious holes: I’ve been able to find some pre-rigged and pre-animated models online that can serve as a great starting point. As a reference, here is a free model from SketchFab - a simple rigged skeleton with 6 built in animations: https://sketchfab.com/3d-models/skeleton-character-low-poly-8856e0138f424d68a8e0b40e185951f6 When exporting to USD from Blender, I haven’t been able to export more than one animation per USD file. Is there a workflow to export multiple animations in a single USDC file, or is this just not possible? As a temporary workaround, here is a python script I’ve been using to loop through all Blender animations, and export a model for each animation: import bpy import os # Set the directory where you want to save the USD files output_directory = “/path/to/export” # Ensure the directory exists if not os.path.exists(output_directory): os.makedirs(output_directory) # Function to export current scene as USD def export_scene_as_usd(output_path, start_frame, end_frame): bpy.context.scene.frame_start = start_frame bpy.context.scene.frame_end = end_frame # Export the scene as a USD file bpy.ops.wm.usd_export( filepath=output_path, export_animation=True ) # Save the current scene name original_scene = bpy.context.scene.name # Iterate through each action and export it as a USD file for action in bpy.data.actions: # Create a new scene for each action bpy.context.window.scene = bpy.data.scenes[original_scene].copy() new_scene = bpy.context.scene # Link the action to all relevant objects for obj in new_scene.objects: if obj.animation_data is not None: obj.animation_data.action = action # Determine the frame range for the action start_frame, end_frame = action.frame_range # Export the scene as a USD file output_path = os.path.join(output_directory, f"{action.name}.usdc") export_scene_as_usd(output_path, int(start_frame), int(end_frame)) # Delete the temporary scene to free memory bpy.data.scenes.remove(new_scene) print("Export completed.") I have also been able to successfully export rigging armatures as a single Skeleton - each “bone” showing getting imported into Reality Composer Pro 2.0 when exporting/importing manually. I would like to have all of these animations available in a single scene to be used in a RealityView in visionOS - so I have placed all animation models in a RCP scene and created named Timeline Action animations for each, showing the correct model and hiding the rest when triggering specific animations. I apply materials/textures to each so they appear the same, using Shader Graph. Then in SwiftUI I use notifications (as shown here - https://forums.developer.apple.com/forums/thread/756978) to trigger each RCP Timeline Action animation from code. Two questions: Is there a better way than to have multiple models of the same skeleton - each with a different animation - in a scene to be able to trigger multiple animations? Or would this require recreating Blender animations using skeleton rigging and keyframes from within RCP Timelines? If I want to programmatically create custom animations and move parts of the skeleton/armatures - do I need to do this by defining custom components in RCP, using IKRig and define movement of each of the “bones” in Xcode? I’m looking for any tips/tricks/workflow from experienced engineers or 3D artists that can create a more efficient/optimized workflow using Blender, USD, RCP 2 and visionOS 2 with SwiftUI. Thanks so much, I appreciate any help! I am very excited about all the new tools that keep evolving to make spatial apps really fun to build!

Apple's new Spatial Personas use Gaussian Splatting, but I have not found any APIs for visionOS to display a Gaussian Splat like a PLY file. Am I just missing the Apple documentation? If not, are there common practices developers are using for displaying Gaussian Splats in visionOS?

Hello, I'm developing a visionOS application for Apple Vision Pro that aims to scan unknown physical objects, capture their 3D data (such as meshes or point clouds), and export them as 3D models. Ideally, I'd also like to visualize these reconstructions in real-time within the headset. This functionality is similar to what's available in Reality Composer on iPad and iPhone, but I'm seeking to implement it natively on Vision Pro. I've reviewed the visionOS documentation but haven't found clear guidance on accessing LiDAR depth data or performing scene reconstruction. Specifically, I'm interested in: 1.Accessing LiDAR or depth data from Vision Pro's sensors. 2.Utilizing ARKit's scene reconstruction capabilities on visionOS. 3.Exporting captured 3D data as models (e.g., USDZ or OBJ formats). Are there APIs or frameworks in visionOS that support these features?

I have an open Feedback conversation with Apple on this topic, but I am curious if others have run into this, or want to try out my sample code in their set up. there are two API’s for reading controller buttons, axis, and D pads: GCPhysicalInputProfile and GCControllerLiveInput. There are inconsistencies in behaviour between the two of them. Apple recommends we use GCControllerLiveInput, however, there are some capabilities on these controllers that are only accessible through GCPhysicalInputProfile, as I’ll discuss below. PSVR2 R2/L2 buttons, a.k.a. triggers, have force input analogue values. These can only be accessed on GCPhysicalInputProfile PSVR2 thumbstick direction values are read through “axes” on GCPhysicalInputProfile, but only “dpads” on GCControllerLiveInput on both GCPhysicalInputProfile and GCControllerLiveInput, All pressed events of all buttons are fired properly using generic aliases ( Trigger, Grip ,Menu, Right Thumbstick, Left Thumbstick, Right Button A & B (Circle & Cross), Left Button A&B (Triangle and Square) ). Apple reserves the system button as the equivalent of a home button for the OS. on GCPhysicalInputProfile, touch events are fired when the button is also pressed, but not for only touches. on GCControllerLiveInput , Touch events only works for the following buttons: Left Thumbstick, Right Thumbstick, Right Button A (Circle), and Right Button B (Cross). But Right Button B touch event isn’t labelled correctly, it fires as the Right Button A event. I observed this inside ALVR which uses a polling based approach to event processing: https://github.com/alvr-org/alvr-visionos/blob/17b5968f9d894944b53e97134b39dfce0993302a/ALVRClient/WorldTracker.swift#L301 To simplify to see this on a very simple app, I used the Apple example TrackingAccessories application: https://developer.apple.com/documentation/ARKit/tracking-accessories-in-volumetric-windows I’ve attached the code that replaces the AccessoryTrackingModel class. I added code that prints out what is touched/pressed, see the trackAllConnectedSpatialControllers method: https://github.com/svrc/TrackingAccessories

How can I request access to Enterprise API for VisionPro with an individual developer account? I wanted it for learning and testing

Is there a way to stop a Reality Composer Timeline ? And restart it later on. For me it looks like you can only start a timeline via notification. and related to it. i have the issue that if the notification to start a certain timeline happens twice or more, it looks as if the timeline actually plays multiple times and animations start to glitch and jump. what is best practise here to avoid this.

Hi! I have been struggling with this for a little while and most of what I've found has not helped much. I hope to find more success here. Essentially, I have a model I've made in Blender. I rigged it using Auto Rig Pro, and I've also used ARP to add a Mixamo animation to it. That all works fine in Blender. However, when I try to import this model into RCP, I don't get the animation. The "default subtree animation" is completely empty. I attribute this to my lack of experience in this field but here's what I've attempted thus far: Pushing the Mixamo keyframes into an NLA strip. I'm pretty sure this is the correct line of action, but I'm definitely not doing something right. Baking the animation (?) I've made sure that I have animation checked when I export the model! Any ideas or reference projects would be lovely. I haven't really found much that has pushed me in the right direction. This project is, unfortunately, kind of time sensitive, so I would appreciate help ASAP. Thank you and let me know if I can add anymore context!

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)?

Hello, I've pre-ordered the Logitech Muse with hopes of developing with it, but have yet to find any documentation relating to the capabilities it will have/any APIs that will be available to take advantage of the Muse. Is anyone aware of what might become available? Thank you in advance.

It's all about notifications to trigger actions from RCP's new Timeline system. From Compose interactive 3D content in Reality Composer Pro I am actually starting to confuse why there was need to use Entity.applyTapForBehaviors in code to trigger content in Behaviors Component. Simply because in Behaviors Component, we have chosen OnTap to allow a "Tap Notification" to trigger our action (on a selected target object). Then I guess by selecting OnCollision this trigger, I should write something like CollisionEvent.entityA.applyCollisionForBehaviors, which we don't have. And ofc the collision on my object won't trigger this action (because I only did things in RCP not in code). Ignoring this post has pointed out we could use Behaviors Component's OnNotification to trigger something for now. I found that I could still use OnTap trigger but actually put my code Entity.applyTapForBehaviors under my subscribed collision's begin event. That actually works better than OnCollision So what is the design principles here? And how could I trigger a collision notification to let my Behaviors Component's OnCollision actually works?

Has Roomplan been abandoned? Two years have gone by without comments from Apple on improvements. Are the improvements behind the scenes? Is there going to be any major updates?

What is the reason the hand-tracking joints have these axes? I'm trying to create a virtual hands model and that's a mess.

Goal: To render in an apple vision pro app, the solid-mechanics 3D simulation results coming form an FEA code. Starting point: I have surface vtks with deformations on each node. Each time step has a a mesh with the nodal coordinates. This is straighforward translatable to a usd MeshSequence. Unfortunately, the results cannot be simplified to a scaling o linear transformation as you would do with other game-oriented animations. Tools: Right now, I am using Xcode and reality composer pro (RCP) to build the scenes. Technical limitations: I am aware that RCP can do animations with BlendMesh and skeletons and that MeshSequence is not a problem. Progress: Coverting to the sequence of vtk meshes to a usd MeshSequence is straighforward. This animates correctly in Preview and Blender (see screenshot). I managed to convert from MeshSequence to multiple keys and BlendMesh. This also animates correctly in Blender and preview. Unfortunately, the BlendMesh of multiple blended meshes shows a zero animation time in RCP (see screenshot below) Also, see below usda file scheme for the animation. Of course I am not showing full vectors such as faceVertexCounts, faceVertexIndex, normals. Question: what is the right set up to create a BlendMesh animation that RCP will correctly import and animate, form a set of Meshes or multiple key shapes?

I’ve been having some issues removing anchors. I can add anchors with no issue. They will be there the next time I run the scene. I can also get updates when ARKit sends them. I can remove anchors, but not all the time. The method I’m using is to call removeAnchor() on the data provider. worldTracking.removeAnchor(forID: uuid) // Yes, I have also tried `removeAnchor(_ worldAnchor: WorldAnchor)` This works if there are more than one anchor in a scene. When I’m down to one remaining anchor, I can remove it. It seems to succeed (does not raise an error) but the next time I run the scene the removed anchor is back. This only happens when there is only one remaining anchor. do { // This always run, but it doesn't seem to "save" the removal when there is only one anchor left. try await worldTracking.removeAnchor(forID: uuid) } catch { // I have never seen this block fire! print("Failed to remove world anchor \(uuid) with error: \(error).") } I posted a video on my website if you want to see it happening. https://stepinto.vision/labs/lab-051-issues-with-world-tracking/ Here is the full code.

Hi, we have been working on an application that attaches a hand model to the users hands. Apple provides an animating hand models in visionOS project that is a useful starting point. https://developer.apple.com/documentation/visionOS/animating-hand-models-in-visionOS We have been trying to create our own hand model to attach but have had some issues with how it is attaching to the hand. For our hand model we want to include the forearm all the way up to the users elbow. I have attached a sample project of what our code currently looks like so you can run it. Just select show immersive space to attach the models. The left hand model is the space glove that we were trying to mirror. The right hand model is our model that we have been using. I have mapped each of the joints to the pertaining joint name on our model. The first issue we are having seems to be based around the placement of the forearm. It attaches itself at the wrist. The second issue seems to be around rotation. Our team is looking for some guidance on what needs to change in order to map this model correctly. Thanks in advance!

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.

I'm developing a visionOS panorama viewer app where I need to implement an auto-hiding floating menu in immersive space. The menu should: Show for 3 seconds when entering immersive mode Auto-hide after 3 seconds, Reappear when user taps anywhere (using SpatialTapGesture). Buttons should respond to gaze + pinch interaction The Problem: When I add .windowStyle(.plain) to achieve transparent window background for the auto-hide effect, all buttons in the menu become completely unresponsive to gaze + pinch interaction. The buttons only respond to direct finger touch (poking). Without .windowStyle(.plain): Buttons work correctly with gaze + pinch, but I cannot achieve transparent window background for hiding. With .windowStyle(.plain): Window can be transparent, but buttons lose gaze + pinch interaction. Code: App.swift: @main struct MyApp: App { @StateObject private var model = AppModel() var body: some Scene { WindowGroup(id: "MainWindow") { ContentView() .environmentObject(model) } .defaultSize(width: 900, height: 700) .windowResizability(.contentSize) .windowStyle(.plain) // <-- This causes the interaction issue ImmersiveSpace(id: "ImmersiveSpace") { ImmersiveView() .environmentObject(model) } } } ContentView.swift (simplified): struct ContentView: View { @EnvironmentObject var model: AppModel @State private var isMenuVisible: Bool = true var body: some View { VStack { if model.isImmersiveViewActive { if isMenuVisible { // This menu's buttons don't respond to gaze+pinch immersiveControlMenu } } else { mainMenuButtons } } .glassBackgroundEffect() } private var immersiveControlMenu: some View { HStack { Button("Exit") { exitImmersiveSpace() } .buttonStyle(.bordered) // Also tried .plain, same issue } .padding() .glassBackgroundEffect() } } ImmersiveView.swift: struct ImmersiveView: View { @EnvironmentObject var model: AppModel var body: some View { RealityView { content in // Panorama sphere let sphere = ModelEntity(mesh: .generateSphere(radius: 1000), materials: [material]) content.add(sphere) // Tap detector for menu toggle let tapDetector = Entity() tapDetector.components.set(CollisionComponent(shapes: [.generateSphere(radius: 900)])) tapDetector.components.set(InputTargetComponent()) content.add(tapDetector) } .gesture( SpatialTapGesture() .targetedToAnyEntity() .onEnded { _ in model.shouldShowMenu = true } ) } } Environment: Xcode 26.2 visionOS 26.3 Vision Pro device Questions: Is .windowStyle(.plain) expected to affect button interaction behavior? What is the recommended approach to achieve a transparent/hidden window in immersive mode while maintaining button interactivity? Is there an alternative to .windowStyle(.plain) for hiding window chrome in visionOS? Thank you for any guidance!

This post documents an issue I reported in feedback FB19610114 and see if anyone knows of a workaround. Here is a copy of the feedback. Short version Manipulation (SwiftUI OR RealityKit) fails to translate entities after changing rooms. By changing rooms, I mean a human wearing an Apple Vision Pro leaving one room and entering another room. Once this issue occurs, it impacts all apps that use these features. A device restart is the only solution I have to fix it. Feedback FB19610114 This is an odd one. I'm using the new Manipulation Component in visionOS 26. Most of the time this works well. Sometime it stops working and when it does the only way to get it working again is to reboot the headset. When this happens, I can continue to rotate and scale items, but translation no longer works. It is as if the item is stuck to a fixed point in the parent scene (window, volume, etc). When this bug occurs, it affects every app across the entire operating system that is using manipulation, including the RealityKit component AND the SwiftUI version. This is not limited to one app and is not limited to apps that I am working on. Once this error occurs, it affects literally any application across the operating system that is using this API, including apps from Apple. I won't speculate on the cause of this, but I do know of one way where I can always get it to happen. Here is how to reproduce it: Make an Xcode project with a single entity that uses the Manipulation Component. There is no need to customize the configuration of this component. The default implementation will work. Build and run this app on device. You can keep running from device or quit and launch the app like normal on device. Open the app and manipulate the entity - it should work as expected. Physically walk into another room. It is vital that you leave the current room that you are in and enter a different room entirely. Use the digital crown to recenter your view and bring your window or volume to you. Test the manipulation on the entity again - it should still be working as expected at this point. Physically, move yourself and your headset into the original room where you started. Use the digital crown to recenter your view and bring your window or volume to you. Test the manipulation on the entity again - you should now see the issue. When I follow the steps above, then 100% of the time manipulation translation stops working at this point. It will impact any application using this API. The only way to fix it is to restart my headset. A few points to keep in mind It does not matter if an app is actively being run from Xcode. When this occurs, it impacts every single app, not just one. When this occurs, rotation and scaling continue to work, but the entity/view cannot be translated. This impacts BOTH the SwiftUI version and the RealityKit version. When this occurs, the only way to "fix" it is to reboot the device.
