X3D Version 4

X3D® Version 4 is a major upgrade to the Extensible 3D (X3D) Graphics International Standard that aligns with the HTML5 Recommendation. This is major work in progress, expected to include several future versions.  This effort is driven by the X3D Graphics Working Group with regular community outreach.

X3D is always evolving, and the Web3D Consortium Standards Strategy carefully guides all these improvements.  X3D Version 4 enables authors to publish interactive 3D content anywhere on the Web, without restrictions or plugins.  Next-generation evolution + revolution is combined with archival compatibility of existing legacy content.  Please see

Normalizing interaction (event model) semantics with HTML5 can further open up X3D for the vast majority of Web authors.  The Web3D Consortium has identified X3DOM and Cobweb as prototypes for the next generation X3D Version 4.0 that support direct integration into HTML5 webpages without the use of a browser plug-in. The Consortium and the X3D community are working closely with open-source exemplars to maintain and expand the X3D standard as it progresses and moves into full browser support. The Consortium also continues to support all existing X3D and VRML content.

Steady progress towards X3D Version 4 continues.  We cordially invite you to Join Web3D as we continue to reliably build a stable foundation that establishes 3D graphics as a "first-class citizen" in the World Wide Web.
