glTF™ is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by engines and applications. glTF minimizes the size of 3D assets, and the runtime processing needed to unpack and use them. glTF defines an extensible, publishing format that streamlines authoring workflows and interactive services by enabling the interoperable use of 3D content across the industry.
Khronos has released a new version of the glTF specification in preparation for submitting glTF 2.0 as an International Standard
The new glTF 2.0.0 specification does not introduce technical changes that will directly impact existing tools and engines, but it aligns glTF with the rigorous drafting criteria needed to be accepted as an International Standard. The new specification incorporates technical clarifications, bug fixes, and is now authored in the AsciiDoctor markup language with the source available under CC-BY 4.0 on GitHub for easier community feedback, contributions, and downstream remixing.

glTF is constantly evolving to bring new capabilities and improvements to the file format. Here are some of the most significant developments.
glTF can now represent material properties such as refraction, color attenuation, and volumetric properties.PRESS RELEASE
Universal distribution of supercompressed GPU textures; open source KTX 2.0 tools and guides released.PRESS RELEASE
New Physically Based Rendering extensions for Clear Coat, Transmission and Sheen continue to build a powerful, interoperable, material model for the glTF ecosystem.PRESS RELEASE
With a new collaborative agreement, the organizations will use the glTF 3D asset standard to share 2.8M 2D images and 3D models into the public domain.PRESS RELEASE
The 3D Formats Working Group welcomes feedback from implementers, engine developers, content creators, and artists to influence glTF’s evolution, and there are several ways to follow the latest glTF developments, get questions answered and make suggestions for improvement.
Any company that wishes to participate directly in the 3D Formats Working Group, which is responsible for the glTF, KTX and COLLADA specifications, can join the Khronos Group for access to all its standardization activities. The 3D Formats group works closely with the 3D Commerce Working Group which brings together industry-leading e-commerce companies to enable the seamless design, manufacture, and presentation of 3D products across diverse consumer platforms to reach millions of end-users.
