The tools enable delivery of dynamic 3D scenes composed of glTF (GL Transmission Format) objects, spatial audio, and haptic elements, transported via the 5G Media Streaming (5GMS) framework (TS 26.512). Designed for developers exploring immersive media delivery and XR experiences on 5G devices and platforms. For the full glTF extension support matrices and how the tools map to the standard, see Implementation Detail; to see one assembled scenario already running, see the Tutorials.

Standards implemented
ISO/IEC 23090-14ISO/IEC 23090-14 (MPEG-I Scene Description, the format that describes how 3D objects, media and audio are composed into a scene), plus the MPEG glTF 2.0 extensions listed on Implementation Detail. 3GPP TR 26.928 (Extended Reality (XR) in 5G) is the background study of use cases and requirements this work responds to, not a specification the tools implement; TS 26.512 (5GMS transport) is explicitly out of scope today (see Implementation Detail for the detail).
See XR on the Standards portal for version history and 5G-MAG's own standards contributions.

Repositories & Releases
rt-xr-gITFastFast glTF loader extensions for immersive media assets in Unity.
rt-xr-maf-nativeThis repository provides media pipelines implementations supporting the 5G-MAG Reference Tools XR Player Unity 3D project. Media pipelines are plugins for the XR Player's media player implementation of the Media Access Functions API (MAF) defined in ISO/IEC 23090-14.
rt-xr-unity-playerThe XR Unity Player is an interactive and XR-capable glTF scene viewer implemented in Unity3D. It supports glTF extensions specified in the MPEG-I Scene Description framework (ISO/IEC 23090-14).
