Universal Scene Description (USD) is a framework for interchange of 3D computer graphics data. The framework focuses on collaboration, non-destructive editing, and enabling multiple views and opinions about graphics data.[1] USD is used in many industries including visual effects, architecture, design, robotics and CAD.[2] It is developed by Pixar and was first published as open source software in 2016.[3]

File formats[edit]

File formats used by the standard include:[4][5]

  • .usd, which can be either ASCII or binary-encoded
  • .usda, ASCII encoded
  • .usdc, binary encoded
  • .usdz, a package file which is a zero-compression, unencrypted zip archive, which may contain usd, usda, usdc, png, jpeg, m4a, mp3, and wav files.
