Revision as of 19:30, 7 August 2014

The Web3D 2014 Conference program schedule includes multiple X3D Workshops on Future Graphics Standards.

Moderators: Don Brutzman (Naval Postgraduate School), Dick Puk (Intelligraphics) and Leonard Daly (Daly Realism).

This page elaborates on the agenda topics. We are collaboratively adding key points. Volunteer scribes will keep minutes so that a workshop report emerges.

X3D Compressed Binary Encoding (CBE) Geometric-Compression Algorithm Candidates

Scheduled time: 0900-1030. Goal outcomes:

Review and improve all published plans & milestones

Review Fraunhofer geometric-compression approach in detail, compare to all of the established X3D metrics

Summary of Efficient XML Interchange (EXI) data compression and XML Security to replace Fast Infoset (FI) in existing X3D CBE Specification

Efficient XML Interchange (EXI)

The World Wide Web Consortium (W3C) supervises these open standardization efforts with contributions by many companies, universities, agencies and individuals to continually improve these capabilities.

NPS student-driven research continues to provide significant explorations of XML-based compression and decompression techniques. Many opportunities are emerging.

  • Snyder, Sheldon L., Efficient XML Interchange (EXI) Compression and Performance Benefits: Development, Implementation and Evaluation , Master’s Thesis, Naval Postgraduate School, Monterey California, March 2010. Also available: poster.
  • Williams, Jeffrey Scott, Document-based Message-centric Security using XML Authentication and Encryption for Coalition and Interagency Operations , Master’s Thesis, Naval Postgraduate School, Monterey California, September 2009.

Currently NPS participates in EXI working-group activities as liaison member for Web3D Consortium work improving the X3D Graphics Compressed Binary Encoding (CBE).

  • OpenEXI Open-Source Java Implementation

We support open Web standards and actively contribute to the OpenEXI project.

   OpenEXI open-source codebase and OpenEXI Apache Incubator proposal
   OpenEXI introduction video and whitepaperEfficient XML Interchange (EXI)

Shall we have a public mesh “contest” or “bakeoff” to confirm that your approach is ready for prime time?

Decide on readiness to proceed with next milestones

X3D 3.4 Evolution

Scheduled time: 0900-1030. Goal outcomes:

Review all planned technology additions

  • Working groups and individual contributions are currently defining future goals and requirements.

Determine technology and specification contributors, responsible working groups

  • CAD
  • H-Anim
  • Geospatial

X3D JSON

  • Technical quicklook
  • Where to define an encoding in X3D Specifications

Achieving two independent implementations and X3D scene conformance tests

Next steps and 2014 timeline

Lunch discussions

Scheduled time: 1200-1300. Participants will order lunch in the morning, sandwiches to be delivered to a good spot near the meeting room.

X3D 4.0 / X3DOM / HTML5 Revolution

Scheduled time: 1300-1500. Goal outcomes:

Review and improve all published plans & milestones

  • Major technology under consideration: HTML5/Declarative 3D/X3DOM
  • Major technology under consideration: Mixed and Augmented Reality (MAR) Continuum (formerly ARC)

Confirm status of technology components, add to v3.4 list as appropriate

Evolution/convergence strategy for X3D 4.0, X3DOM, HTML5

Lots of great progress! What's next? Discussion.

Mixed Augmented Reality (MAR) Reference Model
