Runtime 3D Asset Delivery

glTF™ (GL Transmission Format) 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

Participate in the glTF Community

Khronos openly shares draft specifications and related discussions on the public glTF GitHub together with open-source tools and samples. The 3D Formats Working Group welcomes requirements and feedback from implementers, engine developers, content creators, and artists to influence glTF’s evolution—see "Ways to contribute to glTF" on GitHub, or reach out to us on Twitter. Any company that wishes to participate directly in the 3D Formats Working Group may join the Khronos Group for access to all its standardization activities.

glTF™ (GL Transmission Format) is a royalty-free specification for the efficient transmission and loading of 3D scenes and models by applications. glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. 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.
