ForewordISO (the International Organization for Standardization) and IEC (the
International Electrotechnical Commission) form a specialized system for
worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical
committees established by the respective organization to deal with particular
fields of technical activity. ISO and IEC technical committees collaborate
in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the
work. See http://www.iso.ch
for information on ISO and http://www.iec.ch
for information on IEC.
In the field of information technology, ISO and IEC have established
a joint technical committee, ISO/IEC JTC 1. Draft International Standards
adopted by the joint technical committee are circulated to national bodies
for voting. Publication as an International Standard requires approval by
at least 75% of the national bodies casting a vote. See http://www.iso.ch/meme/JTC1.html
for information on JTC 1.
International Standard ISO/IEC 14772 was prepared by Joint Technical
Committee ISO/IEC JTC 1, Information technology, Subcommittee 24,
Computer graphics and image processing, in collaboration with The Web3D Consortium, Inc. (http://www.web3d.org)
and the VRML moderated email list (www-vrml@web3d.org).
ISO/IEC 14772 consists of the following parts, under the general title Information technology -- Computer graphics and image processing -- The Virtual Reality Modeling Language:
Part 1: Functional specification (this part)
Part 2: Scene authoring interface (SAI)
Part 3: UTF-8 encoding
Part 4: XML encoding (X3D)
