This document specifies an architecture and data model for interchange of scene-based media for use in systems and applications that employ renderers for the presentation of immersive media, including audio, visual, tactile and other representations of media types.

The architecture and data model specified in this document applies to use cases where there is a need for interchange of scene-based media for presentation by systems with 3D render-based technologies. One specific application of this document is immersive display technologies that utilize a real-time renderer of 3D media to create their visual presentations, as opposed to a video decoder and renderer of 2D raster-based media. Another application of this document is for the distribution of media assets for use across a large variety of applications comprising the Metaverse.
