Creating a SnowGlobe in visionOS: From Idea to Reality Composer Pro
summary
A complete visionOS snow globe is built as a USD scene using Reality Composer Pro with basic 3D via extrusion and box modeling, plus particle presets, lights and spatial audio; the final app needs about 30 lines of code to hook timelines and behaviors to SwiftUI and to add the required tap gesture. Key gotchas: enable particles in local space or snow moves with the globe, adjust audio rolloff (up to 5), and use notification-triggered timelines to bridge composer actions and app code — the prototype runs as intended.
