Khronos just returned from a dynamic and productive week at SIGGRAPH Asia 2024, which took place from December 3–6 in the bustling city of Tokyo, Japan. With key announcements, a series of well-attended Birds of a Feather (BOF) sessions, and a vibrant networking event, Khronos reaffirmed its position at the forefront of standardization for the 3D industry.

Here are some highlights of Khronos’s activities at SIGGRAPH Asia 2024, from unveiling new initiatives to fostering collaboration across the graphics, web, and XR ecosystems.

Khronos Group announces the release of the glTF Sample Viewer version 1.1 featuring the restructuring of the repository, adding WebP support, enhanced mobile support, adding KHR_animation_pointer support, integrating glTF validator, and more! In this blog, members from UX3D explore the new features and share insights on how it is easier to integrate Sample Viewer into web applications.

The Khronos Group will have a significant presence at SIGGRAPH Asia 2024. The event will take place from 3 – 6 December 2024 in Tokyo, Japan. Attendees will be able to attend the Khronos Fast Forward and BOFs from glTF, OpenXR, Vulkan and Slang. In addition, there will be a joint BOF between the Khronos Group and W3C on how they are cooperating with synergistic standards such as WebXR, OpenXR, WebGPU, WebGL and glTF.

This year, the Khronos 3D Formats Working Group has reached several significant milestones along the roadmap for developing glTF into an interoperable spatial computing format, and has several extension development efforts underway. Many key extensions for spatial consistency, improved material rendering and consistent render fidelity have now reached the Review Draft stage, where they are ready for detailed review and initial testing. There are also several new extensions in the Initial Draft phase, where the Working Group is seeking directional input to ensure specification development aligns with the community’s needs. We are cranking and getting work done!

This blog will review recent ecosystem updates, explain current specs nearing release candidacy, and highlight opportunities for community input, inviting glTF stakeholders to share useful feedback to shape the future development of the glTF ecosystem.

The VRM Consortium, Inc., the creator and advocate of the VRM 3D avatar file format, which is based on the glTF 2.0 open standard, has announced a collaboration with The Khronos Group to advance the international standardization of VRM. Both parties will work together to develop the VRM and glTF formats as global open standards supporting interoperable 3D avatars.

SIGGRAPH is one of the world’s most significant and long-standing conferences focused on computer graphics and interactive techniques. For the Khronos Group, SIGGRAPH represents an essential opportunity to connect with the developers, engineers, artists, and technical professionals that make up the primary users of Khronos standards like ANARI, glTF, OpenXR, WebGL, and Vulkan.

Through Birds of a Feather (BOF) sessions, presentations, networking events, and face-to-face member meetings at SIGGRAPH, Khronos shares new and forthcoming technical breakthroughs, gathers feedback, learns about user needs and promotes best practices. This year, Khronos hosted nine public-facing events over four days: Presentation materials and video recordings for these events are now available on the Khronos SIGGRAPH 2024 Event Page.

The latest update to Ultra Engine, version 0.9.7, introduces a new decals system built into the clustered forward+ renderer. Decals blend seamlessly with glTF material properties including color, normal, metallic-roughness, and transparency. Particle emitters are now implemented, as well as per-entity emission color and texture offsets for easy control of conveyer belts, tank treads, and other texture-scrolling effects. Ultra Engine continues to leverage Khronos technologies to provide up to 10x faster framerates for games and VR applications. Find out about other features included in the latest Ultra Engine release.

The recently completed MPEG-I Scene Description ISO/IEC 23090 standard builds on glTF 2.0 using the MPEG vendor extension framework. The need for a flexible and dynamic scene description solution for immersive experiences had been identified early in the process of specifying technologies for immersive media in MPEG. In looking for a solution to this gap, MPEG reviewed existing technologies to identify formats with a history of being successfully deployed and widely used. The group then evaluated whether one of these formats would satisfy the identified requirements, or whether a new format needs to be defined from scratch. glTF stood out as an exemplary option.

In a glTF meet-up presentation, Khronos members shared the use cases and requirements that lead to choosing glTF, and detailed the architecture of the extensions. This blog summarizes that presentation, explaining the journey to incorporating glTF 2.0 into MPEG-I scene description and how content creators and developers can begin using this new standard to develop interactive real-time applications.

Ultra Engine 0.9.6 introduces a new foliage system using GLSL compute shaders for efficient rendering of dense forests. The engine makes extensive use of Khronos’ glTF file format and PBR rendering reference code. Ultra Engine leverages Khronos technologies to provide up to 10x faster framerates for games and VR applications. Find out about other features included in the latest Ultra Engine release.

After Effects 24.5 continues Adobe’s ongoing overhaul of the software’s 3D toolset. Changes include the option to import 3D models with embedded animations, originally rolled out in beta in April, and now available in the stable release. Animation support is currently restricted to files in glTF/GLB format.

The Khronos 3D Formats Working Group is pleased to announce that the glTF 2.0 Interactivity Extension (KHR_interactivity) specification draft is available for public review and feedback before ratification. This new extension uses behavior graphs, enabling content creators to add logic and behaviors to glTF assets, with a focus on safety, portability and ease of implementation.

The draft specification is now available on the Khronos GitHub page, and the Khronos 3D Formats Working Group is seeking input from all members of the glTF community, including content creators, application developers, and digital content creation tool implementers.

Perfect Corp., the leading AI and AR beauty and fashion technology provider and developer of ‘Beautiful AI’ solutions, announced a significant enhancement to its AI-powered Jewelry VTO. The latest update to Perfect Corp.’s system now supports the upload of glTF 2.0 (Graphics Library Transmission Format) files, streamlining 3D file upload and formatting processes for brand partners in the jewelry and watch industries. The update simplifies 3D model creation by allowing brands to upload wireframe details, texture maps and environmental lighting information of products in one smooth workflow.

Gary Hsu from Microsoft recounts Microsoft’s history of involvement in the 3D Formats Working Group and its work on the glTF file format. Gary details his group’s early work in PBR, helping define glTF 2.0, their participation in the Khronos Working Group meetings, Face to Faces and conferences, and their present involvement.

In a world where 3D content creation and distribution are rapidly evolving, the need for seamless interoperability and shared standards has never been more critical. That’s why the Alliance for OpenUSD (AOUSD) and Khronos Group have today announced a liaison agreement to align and enhance OpenUSD and glTF technologies. This liaison marks a significant step towards unified 3D asset creation and deployment, streamlining the process for developers and end-users alike.
