X3D version 4.0 Development efforts are considering potentially major additions to the baseline X3D architecture.

  • Summary slides here (Oct 2013) summarize this steadily continuing effort
  • Major technology under consideration: HTML5, Declarative 3D, X3DOM, and possibly CSS
  • Major technology under consideration: Augmented Reality Continuum (ARC) (being renamed as Mixed Augmented Reality MAR)
  • Relaxing prior design constraints can enable a broader new basis for X3D integration
  • Normalizing interaction semantics with HTML5 - now a stable W3C Recommendation - can further open up X3D for the vast majority of Web authors

Please contact us if you think additional technologies need to be considered. X3D Futures planning is currently a Web3D Consortium member-only activity.

Backwards and forwards compatibility

The comprehensive forward compatibility of VRML97 and X3D with later-developed X3D versions shows that careful anticipatory design is achievable.

Open questions

  • Are ARC abstract design and X3D AR proposals sufficiently mature to enable integration with HTML5/Declarative 3D/X3DOM issues?
  • Are the previously X3D Layer/Layering components compatible with HTML5 overlay model? Are they still needed, perhaps for multiscreen or CAVE support?
  • Mashup and interoperability support: is anything else needed for broader use with the Web? YouTube etc.


  • Active development of X3D and X3DOM content is tracking HTML 5 capabilities now
  • We participate and contribute to the W3C Community Group for Declarative 3D
