Universal Scene Description (USD) is a standard to promote interop and exchange of 3D scene descriptions between artists, developers and film studios. USDZ is a WYSIWYG editor developed by Apple and Pixar.

USDZ was introduced by Apple in WWDC 2018 as a WYSIWYG editor developed with Pixar, that allows developers to bring objects from Photoshop and Dimension into an AR environment.

Its features according to Pixar includes:

  • Robust schemas for interchange of geometry, shading, and skeletal deformation
  • High performance data retrieval and rendering, including powerful instancing features
  • The ability to package user-selectable content variations, natively
  • A sound architecture that is flexible enough to adapt to future needs
