X3D to International Standard

ISO votes to advance X3D to International Standard

Subject:   [www-vrml] announce:  ISO votes to advance X3D to International Standard

Dick Puk and I are working this week in Breckenridge Colorado at the International Standards Organization (ISO) Working Group 6/8 meetings for Extensible 3D (X3D) Graphics, Humanoid Animation (H-Anim) and SEDRIS.

I'm pleased to report that both parts of the X3D Abstract Specification are now approved for advancement to International Standard, ISO 19775. X3D is the Web3D Consortium's centerpiece for demonstrating open standards for real-time 3D communication. Part 1 is Architecture and Base Components. Part 2 is the Scene Access Interface (SAI). Developed and tested by Web3D working groups, this specification defines the core technical capabilities of X3D scenes. X3D is equivalently implementable by multiple file-format encodings and programming languages, providing unsurpassed interoperability for 3D models.

The vote by 14 separate national committees was unanimous in favor of X3D, with zero negative comments. This is considered a strong response by ISO members. Further work this week includes comment resolution, update submissions and progress planning for the ongoing related specification documents:

        ISO 19774,   Humanoid Animation (H-Anim)
        ISO 19776-1, X3D Classic VRML Encoding
        ISO 19776-2, X3D Extensible Markup Language (XML) Encoding
        ISO 19776-3, X3D Compressed Binary Encoding
        ISO 19777-1, X3D SAI Language Bindings for EcmaScript
        ISO 19777-2, X3D SAI Language Bindings for Java

Web3D/ISO specifications for X3D, H-Anim and VRML97 are freely available online at Draft specifications for the CAD Distillation Format (CDF), programmable-hardware shaders and other technologies are available to Web3D Consortium members participating in Web3D working groups. Worth noting is that all this specification work is subject to the Web3D Intellectual Property Rights (IPR) Policy. Each contribution to X3D and H-Anim has been formally predeclared by Web3D members as either unencumbered or, if patented, royalty free for any use as part of these standards.

Jubilant thanks are due to the X3D Specification Team for amazing expertise and endurance, numerous Web3D companies for implementation and evaluation experience, and the many contributors in the Web3D/X3D/VRML community. The Web3D Board of Directors has provided critical support, guidance and leadership throughout this effort. Special thanks go to Dr. Richard Puk of Intelligraphics Inc., our lead editor and guiding light for all things ISO.

Members and anyone else interested are invited to learn more during our annual Web3D Consortium Member meeting during SIGGRAPH in Los Angeles on Monday August 9. Some of the best fun is just now beginning.

Questions and comments are always welcome. Hooray!

all the best, Don
