AOUSD Alliance (Alliance for OpenUSD), managed by the Linux Foundation, has published the OpenUSD Core Specification 1.0, which defines a universal format and language for describing 3D scenes, optimized for collaboration on 3D content. The specification is presented as an open standard for creating 3D content and exchanging data between different 3D editors and platforms. Companies such as Pixar, Lucasfilm, Adobe, Apple, Amazon, Autodesk, NVIDIA, Sony, Intel, and Meta participated in the development of the specification. Companies like Hexagon, PTC, Renault, Rockwell Automation, Schneider Electric, Siemens, Amazon, IKEA, Epic Games, Cesium, and Esri have announced their support for the standard. <\/p>\n
The specification covers the description of grammar and data types; the data representation and transformation model; composite algorithm; methods for creating and traversing the scene graph; methods for querying values for each scene object; file formats USDA (readable representation), USDC (binary format), and USDZ (package format) for data exchange; tooling for testing and verifying compliance with the specification requirements. To simplify compatibility verification with the standard, a reference implementation example of OpenUSD has been proposed. <\/p>\n
The OpenUSD project, launched by Pixar nine years ago, provides tools for encoding scalable, hierarchically linked, static, and temporally distributed data. OpenUSD includes a set of operators for compositing, resource management, multi-layer processing, and file link management, allowing a series of disparate resources to be connected into a single graphic scene while maintaining the possibility of separate processing and replacement of each resource. To extend OpenUSD, a plugin system has been provided that can be used for integration with other formats and for translating any data into the OpenUSD graphic scene format. \n Kilde: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
