Web3D 2014 Workshops on X3D Evolution/Revolution

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

• X3D Binary Compression Capabilities and Plans

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

• Links of interest at Efficient Messaging

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.

This article describes the potential role of compressed XML and the efficient use of bandwidth for afloat units.
