Publishing portal on Omniverse Exchange

With the upcoming release of a self-publishing experience for Omniverse Exchange, you as a developer will have a powerful channel to expand the user audience for your connectors, extensions, and asset libraries. The publishing portal will provide a workflow for partners and community members to publish applications, connectors, and extensions to be featured in the Exchange. 

Through Omniverse Exchange, Omniverse customers can seamlessly access industry and purpose-built third-party solutions that will accelerate and optimize their workflows. All content undergoes security vetting and quality assurance before being published.

Developers can be among the first to upload extensions or connectors to the NVIDIA Omniverse Exchange Publishing Portal through the early-access program, available by application. Community members are already taking advantage of these developer tools.

Advances to USD

NVIDIA believes that USD is the best candidate to serve as the HTML of the metaverse. USD, an open and extensible ecosystem for describing, composing, simulating, and collaborating within 3D worlds, is now being used in a wide range of industries.

To accelerate the evolution of USD to meet the needs of the metaverse and become the standard language of virtual worlds, NVIDIA is continuing to contribute to the USD ecosystem in all areas. This ranges from education to building custom schemas for specific industry use cases, while providing free USD assets and resources to all audiences.

Key updates for the NVIDIA work in USD

  • Asset Resolver 2.0 support, enabling Omniverse Connector interoperability with any build of USD
  • New and improved USD code snippets with documentation for common workflows
  • USD C++ extension examples for Omniverse Kit, including open-source USD schema examples and tutorials (coming soon)
  • Support for UTF-8 identifiers for full interchange of content encoded with international character sets (coming soon)
  • An open-source text render delegate enabling human-readable debugging and more efficient unit and A/B testing of scene delegate implementations (coming soon)

NVIDIA has developed Omniverse Connectors for a breadth of top industry applications. At GTC 2022, we introduced Connectors for Autodesk Alias, Siemens JT, and Open Geospatial Consortium (OGC) Web Map Service and APIs, now available in beta. Connectors are also in development for Unity, SimScale, and some of the Siemens Xcelerator portfolio.

In addition, new Omniverse Extensions extend the functionalities of Omniverse Apps, including Motionverse from Beijing DeepScience Technology Ltd, in3D, and SmartCow. Prevu3D and Move.AI will soon have extensions available, as well.

SimReady assets for simulation workflows

NVIDIA also released SimReady, a new category of 3D asset. 3D assets for digital twins and AI training workloads need specific, USD-based properties. NVIDIA is developing thousands of SimReady assets, as well as specifications for building them, tailored to specific simulation workloads like manipulator bot training and autonomous vehicle training.

SimReady goes beyond stunning, full-fidelity visuals for 3D art assets. It includes content with attached, robust metadata that can be inserted into any Omniverse simulation and behave as it would in the real world. For developers and technical artists, SimReady content can act as a standard baseline or starting point and evolve over time as simulation tools like Omniverse become more robust.

These assets provide full-fidelity visualization with the intent of photorealism. Core simulation metadata is always included in the assets and can be readily accessed on import of the art asset. SimReady assets also leverage the modular nature of USD to provide flexibility for technical artists generating synthetic data.

SimReady asset attributes for developers

  • Semantic labels to help you train simulation algorithms by identifying the various components of a 3D model in a predictable and consistent way. These labels provide ground-truth arbitrary output variables for annotations within training. 
  • Physical materials that bring simulations closer to reality and enable you to fine-tune how computers see the world with non-visible sensor support like lidar and radar.
  • Rigid body physics for accurate mass and defined center of gravity to help technical artists create simulations that reflect real-world behavior.
  • Defined taxonomy with consistent tagging for search and discoverability, so that assets can be usable across many domains.
  • Robust kinematics and constraints to help you define complex, multi-part relationships and behaviors.
  • Advanced EM materials to unlock behaviors across the light spectrum.
