glTF – 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 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.
NOTE as of September 23, 2021, the glTF 2.0 Specification has been moved to AsciiDoc markup format.

Fidelity TestingWe believe the true usefulness of glTF goes beyond the spec itself; it is an ecosystem of tools, documentation, and extensions contributed by the community. You are encouraged to get involved!
