    • Commonly used for interchange of 3D computer graphics data.
    • Developed in 2016 by Pixar.
    • ASCII, binary or package format.
    • Provides schemas for standard encoding and client API for geometry, shading, model and assets.

Export

  • Export["file.usd",expr] exports a 3D object to a binary USD file. The expr can be any 3D geometric region that is ConstantRegionQ or a Graphics3D object.
  • The export format can be specified with Export["file",expr,"USD"].
  • File formats and file extensions used by the USD specification include:
  • "USD"ASCII or binary encoded
    "USDA"ASCII encoded
    "USDC"binary encoded
