1.0.0#

Core#

Features#

  • Added usdex_core shared library and usdex.core python module, which provide higher-level convenience functions on top of lower-level OpenUSD concepts, so developers can quickly adopt OpenUSD best practices when mapping their native data sources to OpenUSD-legible data models.

Pybind#

Features#

  • Added usdex/pybind, a header-only cxx utility to enable seamless flow between pybind11 & boost_python.

  • Added bindings for all USD types exposed in the public API of the usdex_core library

    • Note: A minimal subset of USD types is supported. More types may be added in the future.

RTX#

Features#

  • Added usdex_rtx shared library and usdex.rtx python module, which provide utility functions for creating, editing, and querying UsdShade data models which represent MDL Materials and Shaders for use with the RTX Renderer.

Test#

Features#

  • Added usdex.test, a python module which provides unittest based test utilities for validating in-memory OpenUSD data for consistency and correctness.

  • Added usdex/test, a header-only cxx utility which provides a more minimal set of doctest based test utilities.

Dev Tools#

Features#

  • Added install_usdex tool to download and install precompiled OpenUSD Exchange binaries and all of its runtime dependencies.

    • This tool supports a variety of USD flavors & versions. See repo install_usdex --help or the online docs for details.

  • Vendored omni.asset_validator python module for validating that USD Data output is compliant and conforms to expected standards.

    • This can be installed via repo install_usdex --install-test

Documentation#

  • Added C++ and Python API docs for all public functions and classes.

  • Added Getting Started article to help learn about & integrate the SDK into a project.

  • Added Authoring USD Data article to briefly introduce each group of functions from usdex_core and usdex_rtx.

  • Added Runtime Requirements article to exhaustively list the files required by our runtime.

  • Added Deployment Options article explaining how to approach common deployments (e.g cli, docker container, DCC Plugin)

  • Added License Notices article covering OpenUSD Exchange SDK and all its runtime dependencies.

  • Added Dev Tools article to explain install_usdex and Omni Asset Validator.
