Hi, I would like to train Gaussian splats from my object captures. So I need a pointcloud and camera positions together with the original photos taken to train GS In an app like postShot. I could do this with Reality Capture, which supports exporting pointclouds and camera position but it does not do well with turntable photogrammetry. While the Apple object capture API does produce really solid results with turntable images. so my question is, can I export camera data from my object captures to use in another application? Or is there may be a plan to at this feature in the future? It would be really helpful in creating ultra realistic, 3-D objects in Gaussian splat format. Thanks for any isuggestions…

当我进入混合空间时，出现一个模型，但模型后面有一个 windowGroup，无法完全查看。如果我想点击进入 mix 空间，我需要使用代码将 windowGroup 移动到另一个位置，而不是手动移动 ![]（“https://developer.apple.com/forums/content/attachment/0471ead0-4c74-43a7-9ecc-12e67e81cec6” “title=WechatIMG31.jpg;宽度=915;高度=777”）

Using a 360 image that I have taken with 72MP with a Insta360 X3 I would like to add those images into my VisionPro and see them surrounding me completely as we expect of a 360 image. I was able to do by performing the described on some tutorial. The problem is the quality. On my 2D window the image looks with great quality. I will still write down the code: struct ImmersiveView: View { @Environment(AppModel.self) var appModel var body: some View { RealityView { content in content.add(createImmersivePicture(imageName: appModel.activeSpace)) } } func createImmersivePicture(imageName: String) -> Entity { let sphereRadius: Float = 1000 let modelEntity = Entity() let texture = try? TextureResource.load(named: imageName, options: .init(semantic: .raw, compression: .none)) var material = UnlitMaterial() material.color = .init(texture: .init(texture!)) modelEntity.components.set( ModelComponent( mesh: .generateSphere( radius: sphereRadius ), materials: [material] ) ) modelEntity.scale = .init(x: -1, y: 1, z: 1) modelEntity.transform.translation += SIMD3<Float>(0.0, 10.0, 0.0) return modelEntity } } Since the quality is a problem. I thought about reducing the radius of the sphere or decreasing the scale. On both cases, nothing changes. I have tried: modelEntity.scale = .init(x: -0.5, y: 0.5, z: 0.5) And also let sphereRadius: Float = 2000, let sphereRadius: Float = 500, but nothing is changed. I also get the warning: IOSurface creation failed: e00002c2 parentID: 00000000 properties: { IOSurfaceAddress = 4651830624; IOSurfaceAllocSize = 35478941; IOSurfaceCacheMode = 0; IOSurfaceMapCacheAttribute = 1; IOSurfaceName = CMPhoto; IOSurfacePixelFormat = 1246774599; } IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfaceCacheMode IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfacePixelFormat IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfaceMapCacheAttribute IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfaceAddress IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfaceAllocSize IOSurface creation failed: e00002c2 parentID: 00000000 property: IOSurfaceName Is there anything I can do to reduce the radius or just to improve the quality itself?

Can I apply .scrollInputBehavior(.enabled, for: .look) to a WebView (wrapped UIViewRepresentable) in a visionOS 26 app? I tried it myself, but I couldn't do it, so I would like to know if there is any way to do this. Best regards.

I noticed that when I drag the menu window in an Immersive View, the entities behind it becomes semi-transparent, and the boundary between virtual and real-world objects is very pronounced. May I ask how does VisionOS implement this effect? Is there any API or technique I can use in my own code to enable the same semi-transparent overlay - even when I am not dragging the menu window?

Hi everyone, I am wondering under which settings the camera(s) were set by the time they were calibrated. For instance, one aspect that is easy to find is the reference resolution of the images taken when calibrating the intrinsics, this is by retrieving intrinsicMatrixReferenceDimensions. Making sure that the principal point is referenced to the by the time resolution used when the calibration was ongoing. However, recently I saw that there are focusing modes that potentially displace the lens' physical position. Settings like: AutoFocusRangeRestriction: none, near, far setFocusModeLocked: Locks the lens position at the specified value, and sets the focus mode to a locked state. My concern lies the impact this focusing lens displacements can have on the intrinsic matrix parameters, like these parameters no longer describe the camera since the lens position has changed. In simple words, what is the focus 'mode'/'range' the cameras were set when calibrating them for intrnisics?

I am running a Spatial Rendering App template demo， it shows “No People Found ” “There is no one nearby to share with”. How can I stream videos rendered by Mac to my vision pro I am using macOS 26.0, visionOS 26, Xcode 26

We use Unity6+VisonOS2.2 to develop an MR Application. App Mode: RealityKit with PolySpatial, In the actual test, we found that when my moving position is more than 80~100 meters away from the starting position of the application, my current position will be reset to Vector.zero, which will cause my application experience to be very bad. Is anyone experiencing the same problem? Is there a solution?

I am seeking a comprehensive pathway to learning Metal programming on VisionOS. The official documentation’s Pathway on Metal is insufficient in this regard. I kindly request that someone create a detailed pathway to assist me in this endeavor. The pathway should encompass the following key areas: Knowledge Base: Understand the fundamental principles of Metal and other frameworks, as well as basic concepts, to prepare for future learning. Metal3 (very important) : Gain a deep understanding of Metal itself, the programming language used to communicate with the GPU on the device to render graphics. This knowledge forms the foundation for all Metal-related tasks. Compositor Services and ARKit (important) : Learn how to display Metal scenes within the Vision device’s space and enable augmented reality (AR) and hand interaction. This knowledge is essential for creating interactive and immersive experiences. Metal Performance Shaders: Acquire expertise in optimizing material rendering to enhance performance. MetalKit: Simplifies the tasks that display your Metal content onscreen. MetalFX: Develop proficiency in using MetalFX to improve rendering efficiency and achieve visually stunning effects. I would appreciate it if you could provide me with a detailed and comprehensive pathway, including the URLs of relevant documents, to guide my learning journey. Thank you for your assistance.

it looks like one week after accepting as a nearby other AVP device... it expires since we are providing our clients for a timeless app to walk inside archtiecture, it's a shame that not technical staff should connect every week 5 devices to work together is there any roundabout for this issue or straight to the wishlist ? thanks for the support !!

At a recent community meeting we were wondering how Apple creates this soft-edge effect around the occlusion cutouts. We see this effect on keyboard cutouts, iPhone cutouts, and in progressive spaces. An example: Notice the soft edged around the occlusion cutout for the keyboard One of our members created some Shader Graph materials to explore soft edges. These work by sending data into the opacity channel of the PreviewSurface node. Unfortunately, the Occlusion Surface nodes lack any sort of input. If you know how to blend these concepts with RealityKit Occlusion, please let us know!

Can apple vision pro can shareplay differents apps at the same time? How about this on the iphone or ipad?

I understand that the system helps maintain user comfort by automatically adjusting the opacity of content in certain situations, like when someone moves too quickly or gets too close to a physical object. The content in front of them dims briefly to allow a clearer view of their surroundings. And I'd like to know the specific distance at which the system begins to show the physical object, or what criteria are used for this adjustment.

My visionOS app can install custom fonts. My visionOS app also lists these fonts as available within the application, and I can see them in a list using CTFontManagerCopyAvailableFontFamilyNames I manually track which fonts have been installed. So far, so good. But here’s my problem: When a user uninstalls a font via Settings, I have no way to tell. That’s because CTFontManagerCopyAvailableFontFamilyNames will still list that font because it’s still available within the application. How can I track these changes in my app when a font is uninstalled via Settings?

I am working on an app that will allow a user to load and share their model files (usdz, usda, usdc). I'm looking at security options to prevent bad actors. Are there security or validation methods built into ARKit/RealityKit/CloudKit when loading models or saving them on the cloud? I want to ensure no one can inject any sort of exploit through these file types.

I've encountered an unexpected crash with RoomPlan on iOS 16 devices. The odd part is the code is protected by an available check, since I'm using newer RoomPlan features. Xcode error dyld[40588]: Symbol not found: _$s8RoomPlan08CapturedA0V16USDExportOptionsV5modelAEvgZ I can repro using the Apple sample code. https://developer.apple.com/documentation/roomplan/create-a-3d-model-of-an-interior-room-by-guiding-the-user-through-an-ar-experience Modify RoomCaptureViewController.swift as follows. Remove try finalResults?.export(to: destinationURL, exportOptions: .parametric) Add if #available(iOS 17.0, *) { try finalResults?.export(to: destinationURL, exportOptions: .model) } else { try finalResults?.export(to: destinationURL, exportOptions: .parametric) } I would have expected this code to at least compile and run on older devices. When the app was targeting iOS 15, the available checks worked as expected and the app is able to launch properly.

Hi! I read this page, about mirroring Vision Pro to another device. Mirror your Apple Vision Pro to another device I wanna know if it's possible mirroring Vision Pro to other Vision Pros with this way. (showing 2D mirroring screen like video play back or spatial video play back) Or are there other ways?

I noticed in the latest macOS beta 3 that there was this update: A new algorithm significantly improves PhotogrammetrySession reconstruction quality of low-texture objects not captured with the ObjectCaptureSession front end. It will be downloaded and cached once in the background when the PhotogrammetrySession is used at runtime. If network isn’t available at that time, the old low quality model will be used until the new one can be downloaded. There is no code change needed to get this improved model. (145220451) I am not noticing any difference to before with the reconstructions I tested so I am assuming it's reverting to the old model but in the logs there is no way to see if it succeeds or fails to download that new model. do you have any more information on what was improved here with some examples and what we should be looking for? also how can confirm the download of that new model has not failed?

I want to pursue for a project involving 3D VR visualisation. I would like to know if there is a 3D stereoscopic camrea setup that is able to connect straight to Apple Vision Pro display yet. Of course, with no compatibility issues with MV-HEVC. Any recommendation is appreciated.

Despite being enrolled, I am utterly unable to locate any option to download 2.2 beta on my Vision Pro. All I see in the system update is that I'm uptodate with 2.1. How do I locate beta download option? thanks
