A Alian\u00e7a AOUSD (Alian\u00e7a para OpenUSD), supervisionada pela Linux Foundation, publicou a especifica\u00e7\u00e3o OpenUSD Core Specification 1.0, que define um formato universal e uma linguagem para descrever cenas 3D, otimizada para colabora\u00e7\u00e3o em conte\u00fado 3D. A especifica\u00e7\u00e3o \u00e9 apresentada como um padr\u00e3o aberto para a cria\u00e7\u00e3o de conte\u00fado 3D e interc\u00e2mbio de dados entre diferentes editores e plataformas 3D. Empresas como Pixar, Lucasfilm, Adobe, Apple, Amazon, Autodesk, NVIDIA, Sony, Intel e Meta participaram do desenvolvimento da especifica\u00e7\u00e3o. Companhias como Hexagon, PTC, Renault, Rockwell Automation, Schneider Electric, Siemens; Amazon, IKEA, Epic Games, Cesium e Esri declararam apoio ao padr\u00e3o. <\/p>\n

A especifica\u00e7\u00e3o abrange a descri\u00e7\u00e3o da gram\u00e1tica e dos tipos de dados; modelo de representa\u00e7\u00e3o e transforma\u00e7\u00e3o de dados; algoritmo de composi\u00e7\u00e3o; m\u00e9todos de cria\u00e7\u00e3o e navega\u00e7\u00e3o pelo gr\u00e1fico de cena; m\u00e9todos de consulta de valores para cada objeto da cena; formatos de arquivo USDA (representa\u00e7\u00e3o leg\u00edvel), USDC (formato bin\u00e1rio) e USDZ (formato de pacotes) para interc\u00e2mbio de dados; e ferramentas para teste e verifica\u00e7\u00e3o de conformidade com a especifica\u00e7\u00e3o. Para simplificar a verifica\u00e7\u00e3o da compatibilidade com o padr\u00e3o, foi proposto um exemplo de implementa\u00e7\u00e3o de refer\u00eancia do OpenUSD. <\/p>\n

O projeto OpenUSD, lan\u00e7ado pela Pixar h\u00e1 nove anos, fornece ferramentas para codifica\u00e7\u00e3o de dados escal\u00e1veis, hier\u00e1rquicos, est\u00e1ticos e distribu\u00eddos no tempo. O OpenUSD cont\u00e9m um conjunto de operadores para composi\u00e7\u00e3o, gerenciamento de recursos, processamento em m\u00faltiplas camadas e gerenciamento de refer\u00eancias de arquivos, permitindo unir uma s\u00e9rie de recursos diversos em uma \u00fanica cena gr\u00e1fica, preservando a capacidade de processamento e substitui\u00e7\u00e3o separada de cada recurso. Para extens\u00f5es do OpenUSD, um sistema de plugins foi desenvolvido, permitindo integra\u00e7\u00e3o com outros formatos e tradu\u00e7\u00e3o de quaisquer dados para o formato de cenas gr\u00e1ficas do OpenUSD.
