X3D Binary Compression Capabilities and Plans

  • Some capabilities for network flexibility
    • Anchor, Inline, LOD and Prototypes for successive retrieval of content
    • Willing to consider integration of progressive mesh technologies, perhaps by a Call for Contributions
    • Patented technologies can be considered, but only if eventual use will be royalty free for X3D use (if accepted)
  • Web3D's X3D and CAD Working Groups each have 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 3D transmission format
