3D graphics compression and streaming technology continues to steadily improve. The Web3D Consortium is making a Call for Contributions to extend the X3D Compressed Binary Encoding. We are looking for component technologies that can help improve the current X3D Compressed Binary Encoding Standard. Geometric compression, information compression, and streaming technologies are of particular interest. Our goal is to develop a revision to the X3D Compressed Binary Encoding ISO Standard in 2013.

Efforts are underway in the international community to evaluate and standardize royalty-free binary compression schemes for 3D objects and scenes. This includes general web and streamable technologies such as EXI, JSON, Ajax, as well as technologies tuned specifically to 3D graphics such as representations of geometry and animation data. Both streaming and  file-based technologies are of interest as we lay the foundation for an open 3D web platform.

We want to emphasize that each individual contribution is not expected to provide an overall comprehensive solution to all Web-compression challenges. Rather, the X3D Working Group is looking for additional technical capabilities that have the potential to work well together within our proven framework. If your capability might fit into this rich mix, please let us know!

We look forward to your contributions and participation in this effort to further X3D Binary Compression capabilities. Inquiries can be sent to the X3D Working Group co-chairs.

Initial Milestone
The Web3D2013 Conference is hosting a free and open meeting on this topic. The meeting is in San Sebastian, Spain at Vicomtech on Wednesday, 19 June 2013 from 1:00 PM to 4:00 PM local time (GMT+0200). X3D Working Group co-chair Dr. Don Brutzman is the session chair. Responses to the X3D Call for Contributions will be discussed and additional candidate technologies will be compared to further these capabilities.
