Replied In ARKit3 Hardware Requirement Clarification, and How to Get Depth Info and Occlusion / Face tracking / Motion Capture for Other Users?
Hiya,IPerhaps the copy on the Product page isn't as plain as it could be. My understanding from testing the APIs and watching the WWDC sessions is this :People Occlusion requires A12 and A12X Bionic Chips (or later)Motion Capture requires A12 and A12X Bionic Chips (or later)Multiple face tracking requires a A12 or A12X Bionic chip AND a TrueDepth CameraSimultaneous Front and Back Camera usage requires A12 or A12X Bionic chip AND a TrueDepth Camera (required for the facial tracking element of the simultaneous usage)ANE is the "Apple Neural Engine", a co-processor in the System On A Chip that Apple uses for machine learning inference on device (presumably a highly optimised matrix co-processor).Motion Capture (as a skeleton) works using the outward (rear) facing camera. Face tracking requires the TrueDepth camera and uses the 'selfie' camera.If you look at the API for RealityKit, all the samples are there : https://developer.apple.com/documentation/realitykitHope that helps.

Replied In How can I create a custom mesh in RealityKit?
I can confirm this works just fine. It's much less than ideal though and I wouldn't recommend it for any use case where you want to use change the geometry in realtime (for example, drawing a spline based on touch interaction)!.

Thirded - being able to walk the verts/faces of a mesh would be 😎

Replied In RealityKit add gestures and animations to Entity/ModelEntity
I've been looking at a similar problem over the last day or so. I had a look in SwiftStrikeTabletop and the in there they cast an Entity from a Reality Composer scene to Entity & HasCollision. Here's a sample I wrote :// Setup AR Session let arConfiguration = ARWorldTrackingConfiguration() arConfiguration.planeDetection = .horizontal arView.session.run(arConfiguration) // Load the "Box" scene from the "Experience" Reality File let boxScene = try! Experience.loadBox() boxScene.generateCollisionShapes(recursive: true) let box = boxScene.greybox as? Entity & HasCollision arView.installGestures(for: box!)This seems to work (although the Rotation gesture doesn't currently appear to respond).

Replied In RealityKit: record BodyTrackedEntity movement and replay it on a ModelEntity
There's probably the start of a solution here : https://developer.apple.com/videos/play/wwdc2019/607/You'll need to write code to record all the transforms and re-apply them, but you can access the skeletal hierarchy at runtime.

Replied In RealityKit, Skeletons, Skinning, and usdz format?
No solutions but a +1, i've had no luck getting even the most basic (non-apple) usdz into XCode. Any help appreciated!
