New Release: Version 2.0 of full ITMF Suite of Specifications

The Immersive Technologies Media Format (ITMF) is a suite of royalty-free specifications that establishes a baseline for an interchange of immersive media. The format is initially intended to be used for interchange amongst industry-standard digital content creation (DCC) tools, i.e. for the packaging and creation of 3D synthetic, computer generated, and natural media, including audio and visual media. As a baseline format primarily for use with DCC tools, assets described by ITMF are agnostic to the specific type of device on which they may be presented. Visual media, for example, will be display-agnostic, so that a subsequent rendering step in a (media and application aware) distribution system can reformat the visual media to match the capabilities of the client display.

The first version of the ITMF suite of specifications, designated version 0.9, was released for public comment by Immersive Digital Experiences Alliance (IDEA) on October 9, 2019.  On February 17, 2023, IDEA released the updated Version 2.0 of three specification documents:  The ITMF Scene Graph Specification, ITMF Data Encoding Specification and ITMF Container Specification.

These are available at no charge, and may be downloaded below.  Please send and questions or comments to Comments@ImmersiveAlliance.org.
