Transposition to ISO/IEC 12113 solidifies glTF's global recognition and adoption as a 3D asset format

Beaverton, OR - August 4, 2022 - Today the Khronos® Group, an open consortium of industry-leading companies creating advanced interoperability standards, announced that its glTF™ 2.0 specification for the efficient transmission and loading of 3D models has been released as the ISO/IEC 12113:2022 International Standard. Khronos has successfully completed the transposition of glTF 2.0 through the ISO/IEC JTC 1 PAS (Publicly Available Specification) Submission Process to solidify glTF's global recognition and accelerate its adoption by industry and other standards. Khronos will continue to evolve glTF as a Khronos specification and regularly update ISO/IEC 12113 with proven, widely available glTF functionality to avoid industry fragmentation. The ISO/IEC 12113:2022 specification is available here.

In May 2021, ISO/IEC JTC 1 approved Khronos as a PAS submitter, one of only 15 SDOs (Standards Developing Organizations) globally that are enabled to submit proven, widely adopted industry standards for transposition to International Standards. glTF 2.0 was submitted to JTC 1 in October 2021 and was unanimously approved as an International Standard by all voting national standards bodies with no requested technical changes.

"In 2013, Khronos launched the glTF initiative with the goal to create a 3D asset format that was as pervasive as JPEG for images - and now glTF, like JPEG, is an International Standard," said Neil Trevett, vice president developer ecosystems at NVIDIA and Khronos president. "ISO/IEC International Standards are recognized throughout the world, and often constitute the technical regulatory basis for public procurement of IT goods and services. Khronos is proud to be an ISO/IEC JTC 1 PAS Submitter, and intends to proactively transpose additional widely-adopted Khronos specifications to International Standards for the benefit of the industry."

Under the JTC 1 PAS transposition process, Khronos retains full control over the glTF specification, and glTF's status as an ISO/IEC standard will not slow its evolution. Khronos will make regular submissions to bring updates and new widely adopted glTF functionality into refreshed versions of ISO/IEC 12113 to ensure that there is no long-term divergence between the ISO/IEC and Khronos specifications. This provides developers the choice to use the Khronos specification that defines the latest glTF functionality and extensions, or ISO/IEC 12113 for the compatible set of glTF functionality that has been approved as an International Standard.

"Congratulations to Khronos on the publication of ISO/IEC 12113! I'm looking forward to future collaboration between ISO/IEC JTC 1 and Khronos," said Phil Wennblom, chair of ISO/IEC JTC 1.

About glTF
glTF™ is a royalty-free specification for the efficient transmission and loading of 3D scenes and models. glTF minimizes the runtime processing to unpack and process 3D assets, while enabling sophisticated pervasive graphics functionality. glTF defines an extensible, common publishing format for 3D content, tools and services that streamlines authoring workflows and enables interoperable use of content across the industry.

About ISO/IEC JTC 1
The International Organization for Standardization (ISO) is an international nongovernmental organization made up of national standards bodies; it develops and publishes a wide range of proprietary, industrial, and commercial standards and is composed of representatives from various national standards organizations. Founded in 1906, the International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for all electrical, electronic and related technologies. ISO and IEC play important roles in facilitating world trade by providing common standards among different countries. The only joint technical committee of the ISO and IEC, ISO/IEC JTC 1, has been developing standards that support information and communications technology advancement across industry sectors for more than 30 years.
