ovui-data-adapters-openusd 0.2.0

Concrete OpenUSD data adapters and renderer-side OpenUSD support.

NVIDIA ovui-data-adapters-openusd

1. What is ovui-data-adapters-openusd?

ovui-data-adapters-openusd is the OpenUSD provider of ovui-data-adapters, the backend boundary of the ovui scene-tooling family — NVIDIA's standalone distribution of the Omniverse omni.ui UI framework. It implements the provider-neutral adapter contracts from ovui-data-adapters-common on top of the OpenUSD (pxr) API, giving ovui-widgets applications a complete standalone USD backend: no Omniverse Kit installation required.

The provider owns its own Usd.Stage opened from the scene file you pass it. The pxr runtime comes either from the optional standalone extra (which installs the supported usd-core wheel) or from an environment that already supplies a compatible pxr, so the same wheel serves both standalone and embedded deployments.

ovui is pre-release software and is not enterprise-supported.

2. What functionalities are available, and who are the target users?

What you can do with it:

• Drive every widget from USD — stage hierarchy, property, transform, and layer/composition adapters behind the common contracts.
• Author with undo — undoable USD-mutation commands (visibility, delete, namespace edits, camera pose, prim creation) plus session-layer authoring support.
• Present rendered viewports — a renderer adapter with camera handling, picking, and selection highlighting; rendered output uses an external renderer such as ovrtx resolved from the active environment or OVRTX_ROOT.
• Stream frames (optional) — the livestream extra adds ovstream for livestream frame delivery.
• Register automatically — installing the wheel registers the openusd provider through the ovui_data_adapters.adapters entry-point group.

Who benefits:

• USD tool & application developers — a working, production-shaped USD backend for the ovui-widgets USD Viewer and custom apps.
• Teams embedding into existing USD environments — reuse the environment's own pxr runtime by installing the plain wheel without the standalone extra.

Installation:

python -m pip install "ovui-data-adapters-openusd[standalone]"

Install the plain wheel (python -m pip install ovui-data-adapters-openusd) when the environment already provides a compatible pxr runtime; do not combine the standalone extra with an environment-supplied pxr. Select the provider explicitly with OVUI_DATA_ADAPTER_PROVIDER=openusd, or let the common registry selection rules choose it.

4. System requirements

• Python 3.10+
• Declared dependencies: ovui-data-adapters-common>=0.1.0, numpy>=1.20
• Optional extras: standalone installs usd-core==25.11; livestream installs ovstream
• A pxr runtime is required at run time — from the standalone extra or supplied by the environment
• NVIDIA RTX-capable GPU + compatible driver for rendered viewport output via ovrtx; ovrtx is external to this package (resolved from the active environment or OVRTX_ROOT), and non-rendered adapter paths work without it

---

5. Licensing

• Governed by the NVIDIA Software License Agreement and the Product Specific Terms for NVIDIA Omniverse.
• Source-available for inspection; pre-release versions are provided AS-IS and are not currently open to external contributions.
• The standalone extra installs the third-party open-source usd-core package — review its license terms before use.

Note: ovui is pre-release Early Access software and is not enterprise-supported. APIs may change before the 1.0 release.
