OpenUSD
OpenUSD is a framework for authoring and exchanging scalable, time-sampled 3D scene data across digital content creation tools. It serves as a 3D scene interchange standard and interoperable data format to ensure consistency and compatibility when transferring environments between diverse graphics applications.
The project functions as an incremental 3D data streamer, transmitting scene descriptions in small increments to allow the loading and display of visual content without interrupting the user experience.
It provides capabilities for 3D scene authoring, standardized data exchange, and the management of interoperable workflows. These features enable the definition of common data formats that different software tools can read and write to maintain consistency across a production pipeline.
Features
- 3D Scene Descriptions - Provides a scalable, time-sampled framework for authoring 3D scene descriptions used across graphics applications.
- Data Format Interoperability - Provides a standardized data format that ensures consistency and compatibility when transferring 3D scenes.
- Composable Scene Assemblers - Implements a non-destructive layer model to assemble complex 3D environments from multiple files and references.
- Composition Engines - Combines multiple scene descriptions by overriding or adding properties through a hierarchical set of precedence rules.
- 3D Scene Interoperability - Transfers scene descriptions between different software tools to ensure data consistency across a production pipeline.
- Data Exchange Standards - Defines common data formats to ensure that different digital content creation tools can read and write scene information.
- Non-Destructive Editing Workflows - Stores scene changes as additive layers that preserve original base data for reversible modifications.
- Object Schema Definitions - Uses a strongly typed system to define the structure and properties of 3D objects and their relationships.
- 3D Scene Data Streamers - Transmits scene descriptions in small increments over a network to allow loading without interrupting the user experience.
- Time-Sampled Attribute Storage - Associates scene properties with specific timestamps to define animations and state changes over a linear timeline.
- Core Libraries and Frameworks - The primary official repository for the Universal Scene Description project.
