.usdz · model/vnd.usdz+zip

USDZ is a container format for AR assets from Apple and Pixar (WWDC 2018): an uncompressed ZIP packaging a USD scene together with textures into a single file that an iPhone opens straight from Safari via a rel="ar" link and places a 3D model on the user's table. Our exporter takes the bbox of an OSM area, extrudes buildings to volume by height (from height tags or building:levels × story, otherwise by heuristic) and assembles a USDZ package with PBR materials. Honest about limits: these are static mesh-only models with no animation, color is a solid fill per building type with no photorealistic facade textures, and buildings are hollow shells without interiors. USD generation requires pxr or trimesh under the hood; the practical export ceiling is about 5 km² to stay under the AR Quick Look limit.
