USD
A 3D scene description format developed by Pixar and extensively promoted by NVIDIA. It supports the description of geometry, materials, hierarchical relationships, and physical attributes of complex scenes, and is widely used in film production and robotics simulation.
Timeline (last 90 days)
NVIDIA Omniverse is a real-time 3D collaboration and simulation platform based on the USD format, allowing multiple software tools and teams to work together in the same virtual scene.
Isaac Sim uses USD (Universal Scene Description) as its scene description standard, and its physics schema (UsdPhysics) defines common semantics such as rigid bodies, joints, and collision bodies.
Different engines interpret USD physics attributes differently; for example, extension attributes such as contact materials and solver iteration counts are often vendor-defined.
USD was originally developed by Pixar to unify the geometry, materials, lighting and hierarchy of complex scenes in animation production.
The core advantage of USD is its support for layered overlaying and real-time synchronization of data from multiple sources within the same scene description.
In AI factory scenarios, building BIM models, CAD assets of electromechanical equipment, and specification parameters of IT racks can each be mounted into the same USD scene as reference layers without being forcibly converted to a unified format.
