The X3D® version 4.0 specification is now ratified by ISO/IEC as an international standard. This latest version continues the tradition of interoperability, long-term stability and royalty-free use while providing powerful new graphics and multimedia capabilities. The Web3D® Consortium's X3D 4.0 spans a cross-platform ecosystem, including other standards such as GLTF, HTML, MIDI and Web Audio for interactive, composable worlds on the Web.

Web3D and Khronos have signed a liaison agreement to cooperatively advance their standards to support Web-based 3D visualization, modeling and streaming. This agreement formalizes the mutual interest of the two organizations to build cohesive ecosystems of related technology standards including X3D and glTF.

Web3D Consortium will exhibit and present the latest innovations in interactive Web3D at the VIRTUAL, SIGGRAPH 2020 Conference, specifically the new X3D4 specification with a new generation of features for better integration with HTML5.
