Alliance for OpenUSD

Our Mission

To foster the standardization, development, evolution, and growth of OpenUSD.

The Alliance for OpenUSD (AOUSD) is an open, non-profit organization dedicated to promoting the interoperability of 3D content through OpenUSD (Universal Scene Description). Standardizing the 3D ecosystem will enable developers and content creators to describe, compose, and simulate large-scale 3D projects and build an ever-widening range of 3D-enabled products and services. Part of the Joint Development Foundation, the Alliance brings together a diverse and inclusive community of participants to provide an open forum for collaborative development and discussion around OpenUSD.

Core Initiatives

Standardization

A foundational goal is to provide a written specification for OpenUSD core functionality. This not only allows for the development of diverse and compatible OpenUSD implementations, but also enables other standards to reference OpenUSD in support of their technology initiatives.

Evolution

AOUSD serves as a key focal point for the coordinated development of new OpenUSD functionality by our members. We’re also committed to pursuing collaborative relationships with other organizations and standards bodies in the 3D ecosystem.

Development

For new functionality where a reference implementation doesn’t already exist in the Pixar OpenUSD repository, AOUSD will provide a repository to house reference implementations. As the definition of essential OpenUSD functionality expands over time, new implementations can be added.

Growth

AOUSD is committed to offering new opportunities for the OpenUSD community of contributors, developers, and users. At the same time, we’ll work to remove friction and barriers for adoption across a wider array of use cases and implementations.

OpenUSD for 3D Interoperability

OpenUSD is far more than just a file format. It’s a comprehensive technology, platform, and ecosystem built to empower 3D creativity and visualization at cinematic scales.

Extensible Framework and Ecosystem for 3D Scenes

OpenUSD is a high-performance extensible framework and ecosystem for describing, composing, simulating, and collaboratively navigating and constructing 3D scenes.

Optimized for Large-Scale 3D Production Pipelines

Created by Pixar Animation Studios, OpenUSD is now being embraced by industries beyond the film industry, including architecture, engineering, construction, automotive, and manufacturing.

Describe, Compose, Simulate, and Collaborate on 3D Projects

OpenUSD gives developers and content creators the unique ability to broaden interoperability across content tools, data types, workflows, and platforms.

Meet the Visionary: Guido Quaroni’s Journey from OpenUSD’s Origins to Adobe’s Creative Future

In this edition of the "Meet the Visionary" series, we spotlight Guido Quaroni, Senior Director of Engineering for 3D at Adobe. A longtime champion of Universal Scene Description (OpenUSD), Guido’s contributions to the development and expansion of the standard have had a lasting impact, first at Pixar and now in Adobe’s mission to make 3D content creation more accessible to all creatives. From Pixar's Innovation to Industry Standard Guido's journey with OpenUSD began in 2012 at Pixar Animation Studios, where he oversaw the engineering team that launched and led the USD project. "OpenUSD began as an internal initiative to unify…
