I want adding grounding shadow on my Entity in RealityView on visionPro. However it seems that the shadow can only appear on another Entity. So I using plane detection in ARKit and add a transparent plane on it to render shadow. let planeEntity = ModelEntity(mesh: .generatePlane(width: anchor.geometry.extent.width, height: anchor.geometry.extent.height), materials: [material]) planeEntity.components.set(OpacityComponent(opacity: 0.0)) But sometimes there will be a border around my Entityon the plane. I do not know why it will happen, and I want remove the border.

I use ARKit for motion tracking. I get the skeleton joint coordinates and use them for animation. I didn't make any changes to the code, but I updated the iOS version from 18 to 26, and modelTransform now always returns nil. https://developer.apple.com/documentation/arkit/arskeleton3d/modeltransform(for:) For example bodyAnchor.skeleton.modelTransform(for: .init(rawValue: "head_joint")) bodyAnchor is ARBodyAnchor. I see the default skeleton on the screen, but now I can't get the coordinates out of it. I'm using an example from Apple's WWDC presentation. https://developer.apple.com/documentation/arkit/capturing-body-motion-in-3d Are there any changes in the API? Or just bug?

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)?

I am working on a project that requires access to the main camera on the Vision Pro. My main account holder applied for the necessary enterprise entitlement and we were approved and received the Enterprise.license file by email. I have added the Enterprise.license file to my project, and manually added the com.apple.developer.arkit.main-camera-access.allow entitlement to the entitlement file and set it to true since it was not available in the list when I tried to use the + Capability button in the Signing & Capabilites tab. I am getting an error: Provisioning profile "iOS Team Provisioning Profile: " doesn't include the com.apple.developer.arkit.main-camera-access.allow entitlement. I have checked the provisioning profile settings online, and there is no manual option for adding the main camera access entitlement, and it does not seem to be getting the approval from the license.

Dear Apple Team, I’m a high school student (vocational upper secondary school) working on my final research project about LiDAR sensors in smartphones, specifically Apple’s iPhone implementation. My current understanding (for context): I understand Apple’s LiDAR uses dToF with SPAD detectors: A VCSEL laser emits pulses, a DOE splits the beam into a dot pattern, and each spot’s return time is measured separately → point cloud generation. My specific questions: How many active projection dots does the LiDAR projector have in the iPhone 15 Pro vs. iPhone 12 Pro? Are the dots static or do they shift/move over time? How many depth measurement points does the system deliver internally (after processing)? What is the ranging accuracy (cm-level precision) of each measurement point? Experimental background: Using an IR night vision camera, I counted approximately 111 dots on the 15 Pro vs. 576 dots on the 12 Pro. Do these match the internal specifications? Photos of my measurements are available if helpful. Contact request: I would be very grateful if you could connect me with an Apple engineer or ARKit specialist who works with LiDAR technology. I would love to ask follow-up questions directly and would be happy to provide my contact details for this purpose. These specifications would be essential for my research paper. Thank you very much in advance! Best regards, Max! Vocational Upper Secondary School Hans-Leipelt-Schule Donauwörth Research Project: “LiDAR Sensor Technology in Smartphones”

https://developer.apple.com/documentation/arkit/arpointcloud https://developer.apple.com/documentation/arkit/arframe/rawfeaturepoints The point cloud (collection of points/features) main intention is a debug visualization to what the underlying tracking algorithm processes and is not designed for additional algorithms on top of that. But, we are utilizing information contained in the points/features collected by ARKit. Currently, the range of rawfeaturepoints is limited to about 10 meter from the device. We see a great chance if the range is unlock. The global localization will be more robust and accurate. ARPointCloud - Apple ARKit - FindSurface YouTube SIdQRiLj2jY

Hello All, I'm desperate to found a solution and I need your help please. I've create a simple cube in Vision OS. I can get it by hand (close my hand on it) and move it pretty where I want. But, I would like to throw it (exemple like a basket ball). Not push it, I want to have it in hand and throw it away of me with a velocity and direction = my hand move (and finger opened to release it). Please put me on the wait to do that. Cheers and thanks Mathis
