Template:Short description Template:Infobox file format
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, CAD, and rendering.[2][3]
History
It is developed by Pixar and was first published as open source software in 2016, under a modified Apache license.[4] Pixar, Adobe, Apple, Autodesk, and NVIDIA, together with the Joint Development Foundation (JDF) of the Linux Foundation, announced the Alliance for OpenUSD (AOUSD) on August 1, 2023 to "promote the standardization, development, evolution, and growth of Pixar's Universal Scene Description technology."[5]
