The file format for 3D immersive worlds, as discussed in the WWDC sessions, is USD (Universal Scene Description). There are multiple types of USD file formats, each suited for different purposes:

  • USDZ: A zip format that packages all dependencies for an asset, such as textures, into an internal file structure. It is great for AR assets.
  • USDC: A binary format that is efficient for storing large amounts of data, such as geometry.
  • USDA: An ASCII format that can be read as plain text, making it suitable for collaborative files where multiple people might be making edits.

For more details, you can refer to the session Optimize your 3D assets for spatial computing (03:55).
