Key Questions Answered

What is Universal Scene Description and how is it used in the metaverse?
Universal Scene Description (USD) is an open and extensible ecosystem for describing, composing, simulating, and collaborating within 3D worlds. Originally developed by Pixar, it supports a variety of industries and is crucial for creating interoperable virtual environments in the metaverse.
What are the innovative features of USD that support collaboration?
USD features layers that allow multiple users to modify a scene non-destructively. This means users can make changes on different layers without affecting the original data, enabling effective collaboration and composability similar to traditional web practices.
How does NVIDIA plan to evolve USD for the metaverse?
NVIDIA aims to evolve USD by adding features like glTF interoperability, geospatial schema support, and real-time proceduralism. These enhancements will ensure USD meets the dynamic needs of the metaverse and supports high-speed updates for digital twin simulations.
