AOUSD Working Groups Progress
Core Specification Working Group
The Core Specification Working Group has achieved several significant milestones since August 2024. A key advancement is the implementation of PEGTL (Parsing Expression Grammar Template Library) in OpenUSD v24.11 's USDA Grammar, establishing clear and modular rules for human-readable USD content interpretation. The group has initiated sample implementation and compliance testing for the composition engine, with Python code that clarifies the LIVRPS algorithm—fundamental to OpenUSD's data aggregation capabilities.
The Working Group has also drafted normative specifications for animation spline interpolation, enabling fine-grained control for creators developing nuanced behaviors in animated characters and digital humans. Additionally, they have enhanced the specification of listOps, a unique OpenUSD data type essential for managing ordered data elements across layer stacks, particularly valuable in workflows ranging from animated feature films to industrial digital twins. The group has also begun exploring automated documentation builds and diagram generation to improve technical content accessibility.
These developments bring broader understanding of foundational concepts and expert guidance for implementing OpenUSD-compliant systems. For the industry at large, this work formalizes the principles of data interoperability for virtual worlds in normative language, while extending concepts like listOps and composition beyond visual effects into industries with specific data and behavioral requirements.
Materials Working Group
The Materials Working Group, representing diverse interests across the USD ecosystem, has embarked on an ambitious initiative to standardize the MaterialX standard library of shader nodes in USD as an ISO specification. This effort will ensure consistent and validated material representation across all OpenUSD-compliant implementations, enabling users to seamlessly transfer physically accurate materials between applications.
The Working Group has established its operational framework and begun drafting precise, normative specifications for standard library nodes. These specifications will be proposed to the MaterialX project for incorporation into their documentation.
