Universal Scene

An open and extensible ecosystem for 3D worlds.

Building the Open Metaverse With
Universal Scene Description

Universal Scene Description (OpenUSD) is more than just a file format, it’s an open and extensible ecosystem for describing, composing, simulating, and collaborating within 3D worlds.

Originally invented by Pixar Animation Studio, USD’s design and features have positioned it to become the open standard that enables the 3D evolution of the internet, the metaverse.

OpenUSD encompasses a collection of fundamental tools and capabilities that accelerate workflows, teams, and projects, whether you are creating assets and environments for large-scale, connected virtual worlds or building the tools that will make these worlds possible.

The Benefits of OpenUSD


Provides a unique, open, extensible framework and ecosystem with APIs for composing, editing, querying, rendering, collaborating, and simulating within 3D virtual worlds.


Enables non-destructive workflows and collaboration in scene creation and asset aggregation so teams can iterate together.


Is file system agnostic, providing an extensible asset resolver to support any data storage model and allow for disparate data sources.


Supports custom renderers in a generalized pipeline thanks to its Hydra rendering architecture that provides flexibility in visualizing data.

Alliance for OpenUSD (AOUSD)

Pixar, Adobe, Apple, Autodesk, and NVIDIA have formed AOUSD, an open, non-profit organization dedicated to fostering the standardization, development, evolution, and growth of OpenUSD.

Collaborating on Open Standards and USD

As a core contributor to open source across many applications such as artificial intelligence, machine learning, and robotics, NVIDIA is investing in the future of USD along with our ecosystem of partners. This will help USD evolve to make the ecosystem more powerful and ensure the metaverse won’t be built by one organization or company.

Universal Scene Description describes geometries, materials, physics, and behavior representations of 3D worlds and is the best open and extensible standard language for the 3D internet.

— Jensen Huang, CEO, NVIDIA

NVIDIA’s contributions to help evolve USD as the open foundation of fully interoperable 3D platforms will be a great benefit across industries.

— Steve May, CTO, Pixar Animation Studios

Beyond media and entertainment, USD will give 3D artists, designers, developers and others the ability to work collaboratively across diverse workflows and applications as they build virtual worlds.

— Rev Lebaredian, Vice President of Omniverse and Simulation Technology, NVIDIA
