What is Universal Scene Description?

Universal Scene Description is an extensible framework and ecosystem for describing, composing, simulating, and collaborating within 3D worlds. Originally developed by Pixar Animation Studios, USD, aka OpenUSD, is more than a file format—it’s an open-source 3D scene description used for 3D content creation and interchange between tools. Its versatility has made it an industry standard in visual effects, architecture, robotics, manufacturing, and more.

Get Started With OpenUSD


OpenUSD (or USD) is the foundation for NVIDIA Omniverse™, a platform of APIs and services that enable developers to easily build tools, applications, and services for 3D workflows based on OpenUSD. Omniverse connects a wide variety of content creation tools to each other and to our real-time NVIDIA RTX™ ray tracing technology.

NVIDIA has expanded on USD by developing new tools, integrating technologies, and providing samples and tutorials. This includes Material Definition Language (MDL), an open-source SDK that produces simple, high-quality shaders as a supported material definition in USD, and USD Physics Schemas for rigid body simulation in partnership with Apple and Pixar. NVIDIA is also working with an ecosystem of partners through the Alliance for OpenUSD (AOUSD)—including Pixar, Adobe, Apple, and Autodesk—to evolve USD as it becomes one of the building blocks in the era of AI and industrial digitalization.

Universal Scene Description for Developers Series: Watch this introductory series by Aaron Luk, a founding developer of Pixar USD and senior engineering manager for NVIDIA Omniverse, to learn about the four USD superpowers developers can leverage to unlock new possibilities in 3D workflows.
