Khronos glTF 2.0 published as an international ISO/IEC standard


The implementation in ISO/IEC 12113 strengthens the worldwide recognition and acceptance of glTF as a 3D asset format

BEAVERTON, Ore., August 4, 2022 /PRNewswire/ — The Khronos® Group, an open consortium of industry leaders developing advanced interoperability standards, announced today that it has published its glTF™ 2.0 specification for efficient transfer and loading of 3D models as ISO/IEC 12113 became: 2022 International Standard. Khronos has successfully completed the implementation 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 will 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) worldwide competent to submit proven, widely used industry standards for implementation into 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 standardization bodies with no requested technical changes.

“In 2013, Khronos launched the glTF initiative with the goal of creating a 3D asset format that was as ubiquitous for images as JPEG—and now, like JPEG, glTF is an international standard,” said Neil Trevett, Vice President Developer Ecosystems at NVIDIA and Khronos President. “International ISO/IEC standards are recognized worldwide and often form the technical regulatory basis for public procurement of IT goods and services. has adapted Khronos specifications to international standards for the benefit of the industry.”

As part of the JTC 1 PAS implementation process, Khronos retains full control over the glTF specification, and glTF’s status as an ISO/IEC standard will not slow down its development. Khronos will regularly submit contributions to bring updates and new widely used glTF features into updated versions of ISO/IEC 12113 to ensure there are no long-term discrepancies between the ISO/IEC and Khronos specifications. This gives developers the choice of using the Khronos specification, which defines the latest glTF functions and extensions, or ISO/IEC 12113 for the compatible set of glTF functions approved as an international standard.

“Congratulations to Khronos on the release of ISO/IEC 12113! I look 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 efficiently transferring and loading 3D scenes and models. glTF minimizes run-time 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 content sharing across the industry.

The International Organization for Standardization (ISO) is an international non-governmental organization composed 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. Established in 1906, the International Electrotechnical Commission (IEC) is the world’s leading organization for the development and publication of international standards for all electrical, electronic and related technologies. ISO and IEC play an important role in facilitating world trade by providing common standards between different countries. The only joint technical committee of ISO and IEC, ISO/IEC JTC 1, has developed standards that support the advancement of information and communication technology in all industries for more than 30 years.
