Call for Contributions: 3D Graphics Compression and Streaming

Share Article

Binary compression and streaming techniques for 3D graphics continue to steadily improve. The Web3D Consortium has issued a Call for Contributions to improve the X3D Graphics international standard.

3D graphics compression and streaming technology continues to steadily improve. The Web3D Consortium is making a Call for Contributions ( to extend the X3D Compression adn Streaming capabilities. The Consortium is 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. The 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.

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. The Consortium looks forward 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 (

Next Meeting:
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.

About the Web3D Consortium:
The Web3D Consortium is a member-driven organization involved in many technical initiatives across the 4D value chain. The Web3D Consortium is a member-funded industry consortium committed to the creation and deployment of open, royalty-free standards that enable the communication of real-time 3D across applications, networks, and XML web services. The Consortium works closely with the ISO, MPEG and has active projects with OGC, DICOM, IMS, KHRONOS and W3C standardization bodies to maximize market opportunities for its membership. The Web3D Consortium leads the charge to insure the interoperability, longevity and ownership of your 3D content. There has been no better time to discuss X3D technologies and also join the Web3D Consortium. To join, please visit
