Revision as of 22:10, 9 August 2013

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

• Major technology under consideration: HTML5, Declarative 3D, X3DOM
• Major technology under consideration: Augmented Reality Continuum (ARC)
• Relaxing prior design constraints can enable a broader new basis for X3D integration
• Normalizing interaction semantics with HTML5 might further open up X3D for 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 forward compatibility

• A major benefit of using the X3D standard is full backwards compatibility with prior VRML97 and X3D content
• X3D version 3.4 Development is proceeding in parallel to enable continued evolution of the current X3D architecture
• Our goal is to maximize, but not necessarily require, backwards compatibility in version 4.0
  • A great majority of X3D nodes and features are likely achievable without change
  • Some X3D features may require import/export conversion for compatibility (ROUTEs and sensors perhaps)
  • A few features might be refactored, deprecated or obsoleted (none yet identified)

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 issues?
• Are X3D Layer/Layering components compatible with HTML5 overlay model? Are they still needed, perhaps for multiscreen support?
• Mashup and interoperability support: is anything else needed? YouTube etc.

Schedule

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