Deploying and developing royalty-free open standards for 3D graphics, Virtual and Augmented Reality, Parallel Computing, Neural Networks, and Vision Processing

The newly released OpenXR Spatial Container extensions standardize system-managed spaces for volumetric 3D apps, similar to how traditional systems place 2D content in desktop windows.

buildingSMART International and the Khronos Group announced a new liaison agreement. It aims to improve interoperability between IFC and glTF, and the first step is exploring how structured information about buildings and infrastructure can be brought into interactive 3D applications more reliably. The agreement sets up a framework for technical dialogue and knowledge sharing, driven by the growing use of AI, digital twins, web-based applications and interactive 3D in the built environment. IFC (ISO 16739-1:2018) is buildingSMART’s open standard for exchanging structured built-asset information. glTF (ISO/IEC 12113:2022 for glTF 2.0) is Khronos’s open standard for efficiently transmitting and loading 3D scenes and models. Both are royalty-free. Under the agreement, the two organisations plan to explore shared use cases and technical requirements for visualising and streaming built-asset models. They will also review existing IFC-to-glTF conversion approaches, identify where they can be improved, and consider practical guidance for software developers.

Mit der Ratifizierung neuer Erweiterungen für den offenen Standard OpenXR treibt das Branchenkonsortium Khronos Group die Entwicklung von plattformübergreifendem Multitasking in virtuellen und erweiterten Realitäten voran. Die neu spezifizierten Spatial Containers etablieren systemverwaltete Räume für dreidimensionale Inhalte, deren Funktionsweise an die etablierte Fensterverwaltung klassischer 2D-Betriebssysteme anknüpft. Entwickler erhalten damit ein einheitliches Rahmenwerk, um räumliche Anwendungen […] The post OpenXR-Erweiterungen: Khronos standardisiert Multitasking für VR und AR appeared first on BornCity.

Le groupe de travail OpenXR de Khronos a publié de nouvelles extensions pour créer une interface de programmation (API) ouverte et multiplateforme dédiée aux systèmes de fenêtrage spatial en XR. Ces extensions introduisent des "conteneurs spatiaux", des espaces gérés par le système où les applications peuvent afficher du contenu XR, à l’image des fenêtres 2D sur un bureau. Elles permettent aux développeurs de concevoir des applications pouvant basculer entre des modes immersifs et des usages multitâches avec le monde réel ou d’autres applications, sur des plateformes XR compatibles. Les conteneurs spatiaux offrent deux modes : un mode "borné" pour le multitâche et un mode "immersif" en plein écran. Leur position est contrôlée par le système, facilitant l’adaptation à différents contextes, comme le suivi de l’utilisateur en déplacement. Les développeurs peuvent tester ces fonctionnalités via des exemples sur GitHub et contribuer aux discussions via Discord, les forums ou le suivi des problèmes techniques.

SGDL Innovation SA is a Swiss-Canadian deeptech company whose technology describes 3D shapes precisely as compact mathematical forms rather than triangle meshes. Each shape is stored only once and can be rendered at any level of detail, from embedded devices to the cloud, including on low-power processors. Used since 2003 in the ISS robotic arm simulator, the technology has contributed to standards since MPEG-4 (AFX). SGDL is also a member of AOUSD and OGC. At Khronos, SGDL aims to bring this technology to ANARI and glTF.
