Programs that open USDZ
FAQ: USDZ for Amuria
Can I open USDZ without an Apple device?
On iPhone/iPad — Safari Quick Look automatically; on macOS — Finder. On Windows/Linux — Pixar's usdview or three.js online viewers. Native USDZ preview outside the Apple ecosystem is weaker than for glTF.
Are there animations and facade textures?
No. Models are static, mesh-only, with no animation (that needs UsdSkel rigging absent from OSM). Color is a solid fill per building type, with no photorealistic textures. Buildings are hollow shells without interiors.
Why is export area-limited?
AR Quick Look recommends files up to ~25 MB and dislikes models heavier than ~200 MB. Extruding a whole metropolis exceeds the limit, so the practical ceiling is about 5 km².
How is USDZ different from glTF?
USDZ is a zipped USD optimized for Apple AR Quick Look (mmap-friendly, single file). glTF is the cross-platform Khronos standard for web/AR/VR. For out-of-the-box iOS AR, USDZ is more convenient.
Where does the building height come from?
From the height tag, if it is set in OpenStreetMap. Otherwise — the number of floors in building:levels at 3 meters each, then a typical height for that type of development, and as a last resort 9 meters.
