Hi, I downloaded a few files from apple developers website, and they are in .reality file format. I wanted to see how they are constructed, but there is no way to open them and look at the content inside (3d model, shader, animation, etc). Is there a way to look at the content of .reality file?

I am developing an ARKit based application that requires plane detection of the tabletop at which the user is seated. Early testing was with an iPhone 8 and iPhone 8+. With those devices, ARKit rapidly detected the plane of the tabletop when it was only 8 to 10 inches away. Using iPhone 15 with the same code, it seems to require me to move the phone more like 15 to 16 inches away before detecting the plane of the table. This is an awkward motion for a user seated at a table. To validate that it was not necessarily a feature of my code, I determined that the same behavior results with Apple's sample AR Interaction application. Has anyone else experienced this, and if so, have suggestions to improve the situation?

Following up on my previous question here: https://developer.apple.com/forums/thread/774262 Having solved the clipping problem, I am now trying to overlay some content in front of the RealityView. However, it looks like any content with transparency does not render in front of the RealityView, while opaque views seem to work; placing content with transparency like glassBackgroundEffect() behind the RealityView in a ZStack causes the entire window to flicker. Additionally, my SwiftUI attachment placed in front of the stereoscopic image plane are invisible if the user look at it straight at 90 degrees. However, if the user look at it from increasing angles from the sides, the attachment gradually turns visible again. Are these behaviors expected? What is a recommended approach to overlay content in front of a RealityView? Thanks!

I am developing an visionos app. I load a .usdz file as a Reality Entity(such as a cabbage). And I want such an effect: When I turn on a desk lamp in real world near the Entity, the surface of the Entity will correctly respond to the light in the real world. I want an effect like this: https://www.reddit.com/r/virtualreality/comments/1as01mm/shiny_disco_ball_reflecting_my_room/ I look up the api such as ImageBasedLightComponent andVirtualEnvironmentProbeComponent in RealityKit、EnvironmentLightEstimationProvider in ARKit，but I do not know how to code. Besides, it will be better if the shadow will also respond to the light correctly.

Hello, esteemed tech developer. I am using the Apple Vision Pro to create an AR assist system about the da Vinci Surgical Robot in a medical surgical suite, and would like to capture eye movement data with tester uniformity. Although the Apple Vision Pro has a superb infrared sensor to monitor eye movement status, Apple does not seem to have open access officially. (I'm aware of many existing discussions about this, but I was still wondering if there might be an option, particularly for research labs.)Here's my FB number.FB16603687

Hi, I am creating an ECS. With this ECS I will need to register several DragGesture. Question: Is it possible to define DragGestures in ECS? If yes, how do we do that? If not, what is the best way to do that? Question: Is there a "gesture" method that takes an array of gestures as a parameter? I am interested in any information that can help me, if possible with an example of code. Regards Tof

Hello, I have downloaded and run the sample object tracking app for visionos. Now I'm working on my own objects for tracking. I have made a model using Create ML using images of my object. However, I cannot see how to convert the Create ML output file (xxx.mlmodel) into a reference object like the files in the sample project. is there a tool for converting them? TIA

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.

We're developing a VisionOS application, where we would like to do product recognition (like food items). We have enterprise entitlements and therefore also main camera access for VisionOS. We send this live camera frames to a trained CoreML model where we will receive 2D coordinates from the model detection prediction. Now, we would like to create a 3D anchor on the detected items so it can be visible for user. The 3D anchor is going to be the class name of the detected item. How do we transform this 2D coordinate from the model prediction to a 3D anchor?

I'm using Unity 2022.3.56f, with Apple VisionOS App Mode set to 'Virtual Reality - Fully Immersive Space'. It seems that the render resolution of my game in the Apple Vision Pro when I build is well below the native resolution of the AVP displays. I can't see a setting in XR Plug-in Management Apple visionOS options, or in Quality settings, to increase the render resolutions. Is this possible? I tried setting: UnityEngine.XR.XRSettings.eyeTextureResolutionScale= 2.0f For example, but this doesn't seem to do anything to the render resolution in the build.

Hi, I'm developing an app for the Apple Vision Pro. Inside the app the user should be able to load objects from the web into the scene and then be able to move them around (dragging and rotating) via gestures. My question: I'm working with RealityKit and use RealityView.. I have no issues loading in one object and making it interactive by adding gestures to the entire RealityView via the .gestures() function. Also I succeeded in loading multiple objects into the scene. My problem is that I can't figure out how to add my gestures to multiple objects independently. I can't use Reality composer since I'm loading the objects dynamically into the scene. Using .gestures() doesn't work for multiple objects since every gesture needs to be targeted to a specific entity but I have multiple entities. I also tried defining a GestureComponent and adding it to every newly loaded entity but that doesn't seem to work as nothing happens, even though my gesture is targeted to every entity having my GestureComponent. I only found solutions that are not usable on Visionos / RealityView like installGestures. Also I tried following this guide: https://developer.apple.com/documentation/realitykit/transforming-realitykit-entities-with-gestures But I feel like there are things missing and contradictory, like a extension of RealityView is mentioned but not shown and the guide states that we don't need to store the translation values for every entity and therefore creates a EntityGestureState.swift file to store these values but then it's not used and a GestureStateComponent is used instead that was never mentioned and contradicts what was just said about not storing values per entity because a new instance of it is created for every entity. Nevermind, following the guide didn't lead me to a working solution.

Using Unity to develop VisionOS program, pressing the right knob of VisionPro during use will exit the Unity space and destroy the model in the space. The model in the space has been disconnected from the SwiftUI interface. After clicking the right knob, return to the system main interface, and then click the right knob again to return to the inside of the program. However, Unity space cannot be restored, and calling the discisWindow method on the SwiftUI interface has no effect, so the interface cannot be destroyed. Is there any solution??

Hi, I'm trying to achieve 3D photo effects using a photo and a depth map, using GeomertyModifier. The offset is getting applied correctly in Reality Composer Pro, and in Xcode, but when I launch the app, the model offset is not getting applied. here are the screenshots of shader graphs and how it looks in the app

Hello Community, I am currently developing an experimental VisionOS app, to investigate the social effects of the new Spatial Persona feature, for my bachelor thesis. My setup includes a simple board game for the participants, in which they can engage with their persona avatars. I tried to use the TabletopKit for this setup, but ran into issues when starting the SharePlay session. When I testes my app, I couldn't see the other spatial persona anymore, despite the green SharePlay button indicating the session started. The other person can see my actions in their version of the app on the board, but can not interact with anything. Also, we are both seat on the default side of the seat. I tried to remove the environment I added, because it doesn't seem to synch with the other player. When I tried the FaceTime feature in the simulator without the environment, I could then see the test robot avatar, but at a totally wrong place. It's seems like it isn't just my environment occluding the seats, but a flaw in the seating process as well. When I tried the FaceTime feature in the simulator on the official test scene (TabletopKit Sample), I got the same incorrect placement and the warning "role(for:inSeatNumber:): The provided role identifier does not match a role in the current template." So my questions are: What needs to be changed so the TabletopKit can handle seating correctly? How can I correctly use immersive scenes in combination with the TabletopKit? I tried to keep the implementation of the TabletopKit example as close as possible, so I think it will enough to look into this codebase for now. I debugged the position of seats and they are placed correctly in front of their equipment. The personas are just not placed on them.

I am experimenting with RealityKit to set up a portal. Everything works, but I was wondering where the scene's origin is with respect to the front of the portal window? From experiments, the origin's X and Y appear to be at the center of the portal window, while the origin's Z appearing to be about a meter behind the portal window. Is this (at least roughly) correct? Is it documented anywhere? PS. I began with the standard visionOS app and edited the Reality Composer Pro file to create the scene.

Still don't understand why no one is clarifying about this Apple Video https://developer.apple.com/videos/play/wwdc2023/10111 At the end of this video, there's an incomplete tutorial about connecting a USDZ with mesh and Skeleton structure to the hand tracking system. No example project is linked, and no one is giving the community any clarification. Please can you help us to understand how to proceed?

Hello, We discovered that a bunch of our old animated models were no longer animated on iOS15 and onwards. After a few days of playing spot the difference between usda files I noticed that all the broken models had an xform called "Scene". Lo and behold, changing the name of that xform fixed the issue on all the models. Even lowercase "scene" makes the animations work again. Is "Scene" a reserved keyword or something? What other keywords do we need to avoid so we can create more robust USDZ files? I'm surprised this issue isn't more widespread considering Blender wraps models in a "Scene" node. At the drive link below you can find two animated cube USDZs. The only difference is the name of one of the xforms. The one with a "Scene" xform is not animated in quicklook (replicated on iPhone 13 iOS v15.2, iPhone 13 iOS v 18.3, and various devices on Browserstack including iPhone 16 iOS v18.3). https://drive.google.com/drive/folders/1dch1WaM9O6mbHy29S6NGWgnSHkZkPiBf?usp=sharing

Hi ! I'm new on this forum, so if I need to update this post to have more info, or anything else, please let me know. I'm using the Apple Vision Pro to develop some app (with unity). To demonstrate what the user see on the headset, I would like to mirror the view on a device (an iPad in this case). I managed to do this without any issue. My problem is that, in the Vision Pro, I have an interface that the user can interact with. But I would like to be able to manage myself the interface on the iPad. What I mean is that the user can (or can't, doesn't matter) see the interface in the headset, and the interface is controlled by myself on the iPad. Is there any way to do this ? Is this a question I should ask on unity's forum ? (I don't think so, because it should be related to the mirroring function non ?)

Here is my code in visionOS 2.3 NavigationSplitView { List { } .navigationTitle("Passwords") } detail: { Text("Hello") .navigationTitle("All") } The font size of "Passwords" and "All" are smaller than the ones in Passwords app.

As I understand it there are two ways I can track a hand, or a joint, in RealityKit: either, create an AnchorEntity, for example AnchorEntity(.hand(.left, location: .palm)) or, set up an ARSession with a HandTrackingProvider ( a lot more code which I haven't repeated here). Assuming this is correct, when would I want to use one over the other?
