  • Some capabilities are available for flexible network transmission
    • Anchor, Inline, LOD and Prototypes for successive retrieval of content
    • Willing to consider integration of progressive mesh technologies, perhaps by a public Call for Contributions
    • Intellectual Property Rights (IPR) protections for X3D specification
      • Patented technologies can be considered, but only when eventual use will be royalty free for X3D use (if eventually accepted)
      • Submitters can restrict patented submissions to working group while under consideration, if desired
  • Web3D's X3D and CAD Working Groups each have member commitments to pursue this continued innovative work in 2012
  • X3D appears to have have an 80% solution already available that meets various requirements for a general 3D transmission format
