Sun Apr 21 19:48:00 PDT 2024

Web3D Consortium is a Standards Development Organization (SDO).  Dick Puk and I continue dedicated, focused efforts on Web3D Standards.  The following document is now ready for Web3D member and X3D community public review.

*	ISO/IEC 19775-2, X3D Scene access interface (SAI) version 4.0
*	https://web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-2v4.0-WD1/Part02/X3D_SAI.html
*	Introduction, Purpose
*	X3D is a file format and related access services for describing interactive 3D objects and worlds. X3D is designed to be used on the Internet, intranets, and local client systems. X3D is also intended to be a universal interchange format for integrated 3D graphics and multimedia. X3D may be used in a variety of application areas such as engineering and scientific visualization, multimedia presentations, entertainment and educational titles, web pages, and shared virtual worlds.
*	This part of ISO/IEC 19775 defines the scene access interface that can be used to interact with X3D worlds both from within the worlds or from external programs.

We invite all comments on this document.

Formal changes have been applied to make this draft standard consistent with:

*	ISO/IEC 19775-1, X3D Architecture version 4.0, 2023
*	https://www.web3d.org/specifications/X3Dv4/ISO-IEC19775-1v4-IS/Part01/Architecture.html
*	https://www.web3d.org/x3d4
*	https://www.web3d.org/specifications/X3dGraphicsStandardsRelationships.png

All changes are applied using version control, and visible to Web3D Consortium members at:

*	https://github.com/Web3DConsortium
*	https://github.com/Web3DConsortium/X3D/tree/master/ISO-IEC19775/ISO-IEC19775-2/ISO-IEC19775-2v4.0/ISO-IEC19775-2v4.0-WD1/Part02

All issues have been discussed on the x3d-public mailing list.  Problems, alternatives, examples, and resolutions are captured in the Mantis issue tracker.  A summary of current, resolved, and open issues is attached.  Ongoing distilled issue details are visible to Web3D Consortium members in Mantis at:

Following public comment, full member review, and Web3D Consortium Board of Directors (BoD) concurrence, this working draft (WD1) will be submitted to:

*	INCITS H3 – Graphics and Imaging
*	INCITS -- the InterNational Committee for Information Technology Standards -- is the central U.S. forum dedicated to creating technology standards for the next generation of innovation. INCITS members combine their expertise to create the building blocks for globally transformative technologies. From cloud computing to communications, from transportation to health care technologies, INCITS is the place where innovation begins.
