Reply to ARKit for BIM
Yes it is possible. Treat bar codes as image anchors. Load the identifiable images based on location. Affix your 3D models to entities attached to the detected image anchors. https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/detecting_images_in_an_ar_experience?cmdf=arkit%20image%20anchor

Reply to How to get SceneKit to update a nodes orientation based on values that update in real time without lagging or stuttering
in UIViewRepresentable.updateUIView, you shouldn't be reloading the scene from disk on each update. that seems expensive if that doesn't make an impact, I'm not familiar with using SceneKit with SwiftUI, so not sure how UIViewRepresentable.updateUIView works with/against a typical SceneRenderDelegate.updateAtTime implementation. fwiw.

Reply to DrawableQueue to RealityKit ShaderGraphMaterial ignoring alpha channel of texture?
I would love to see some sample code showing how you're generating a dynamic texture with DrawableQueue! That said, I can see from the image that your sending UsdUVTexture.RGBA, which has 4 components, to UnlitSurface.Color, which only takes in 3 components. You need to split the RGBA out, then pass the first three into Color, and the last into Opacity.

Reply to Aggregated Data Table (Reporting Table) in CloudKit database
:-) As a developer, one of the things I love about CloudKit is that the cost is paid for entirely by the customers themselves. If we extend that thinking from storage to storage+compute, and we recognize that we have to build a distributed job system anyway, well it just makes sense to use the compute resources that the customer already has.

Reply to Aggregated Data Table (Reporting Table) in CloudKit database
I wish CloudKit had jobs, too, but alas… One idea is to have clients do the job. Check if there's a recent aggregate record, and if not, create one. Sure, you might have several clients doing similar work at similar times, but you won't have the cost of running a server somewhere.

Reply to ARKit - using face recognition while using video
Use AVFoundation to encode a video from each ARFrame.capturedImage. You'll need AVAssetWriter, AVAssetWriterInput, AVAssetWriterInputPixelBufferAdaptor.
