3D Transformations: Utility functions to manipulate 3D transformation data on UsdGeomXformable Prims.
Asset Structure: Utility functions for creating Assets following NVIDIA's Principles of Scalable Asset Structure .
Camera Prims: Utility functions to manipulate UsdGeomCamera and GfCamera data.
Diagnostic Messages (Logs): Specialized handling of OpenUSD TfDiagnostic messages (logs).
Geometric primitives: OpenUSD supports various basic geometric primitives, known collectively as UsdGeomGprims , which are considered more performant for both rendering & simulation.
Light Prims: Utility functions to define, manipulate, and read UsdLux Light Prims.
Line and Curve Prims: Utility functions to create geometric Line and Curve descriptions.
Material and Shader Prims: Utility functions for creating, editing, and querying UsdShadeMaterial and UsdShadeShader objects. This module provides:
Material and Shader Prims for use with the RTX Renderer: Utility functions for creating, editing, and querying MDL Materials and Shaders for use with the RTX Renderer.
Mesh Prims: Utility functions to create polygonal UsdGeomMesh Prims.
Physics Joint Prims: PhysicsJoint Prims define constraints which reduce the degrees of freedom between two bodies.
Physics Material Properties for use with Simulation Engines: Utility functions to define, apply, and bind physics material properties to collision geometry.
Point Cloud / Particle Prims: Utility functions to create UsdGeomPoint prims.
Prim and Property Names: Utility functions to generate valid names and display names for UsdPrims , and valid property names on UsdPrims .
Primvar Data Management: Utilities to author and inspect UsdGeomPrimvars
Python Interoperability for pybind11: Provides pybind11 interoperability for OpenUSD's bound python objects.
Runtime Settings: Some OpenUSD Exchange behaviors are controllable via global static runtime settings, using OpenUSD's TfEnvSetting mechanism.
Schema-defined Attributes: Utility functions for authoring values on UsdAttribute properties that are declared by applied API or typed prim schemas.
SdfLayer Authoring: Utility functions to provide consistent authoring of SdfLayers
Test USD Authoring within doctest test suites.: In C++ usdex::test uses the doctest testing framework. The utility classes and functions within this group use doctest commands in their implementations directly and as such are expected to be used within a running doctest context.
UsdStage Configuration: Utility functions to provide consistant authoring of UsdStages
UsdStage Hierarchy: Utility functions to avoid common mistakes when manipulating the prim hierarchy of a UsdStage .
Versioning sanity checks: Utility functions to verify the expected library versions are being loaded at runtime.
Xform Prims: Utility functions to create UsdGeomXform prims.
