Editing X3D (section)

==Standardization==

X3D defines several profiles (sets of components) for various levels of capability including X3D Core, X3D Interchange, X3D Interactive, X3D CADInterchange, X3D Immersive, and X3D Full. Browser makers can define their own component extensions prior to submitting them for standardisation by the [[Web3D Consortium]]. Formal review and approval is then performed by [[International Organization for Standardization|ISO]]/[[International Electrotechnical Commission|IEC]].

Liaison and cooperation agreements are also in place between the [[Web3D Consortium]] and the [[World Wide Web Consortium]] (W3C), [[Open Geospatial Consortium]] (OGC), [[Digital Imaging and Communications in Medicine]] (DICOM) and the [[Khronos Group]].

A subset of X3D is XMT-A, a variant of [[Extensible MPEG-4 Textual Format|XMT]], defined in [[MPEG-4 Part 11]]. It was designed to provide a link between X3D and 3D content in MPEG-4 (BIFS).<ref>{{cite web|url=http://www.web3d.org/specifications/X3dNodeInventoryComparison-X3dInteractiveMpeg4Interactive.pdf|title=X3D Interactive, X3D MPEG4 Interactive Profile Comparison|website=web3d.org|access-date=10 September 2023}}</ref>

The abstract specification for X3D (ISO/IEC 19775) was first approved by the ISO in 2004. The XML and ClassicVRML encodings for X3D (ISO/IEC 19776) were first approved in 2005.<ref>[http://www.web3d.org/about/faq/#process-3 X3D FAQ – "What is the status of the X3D specification?"] {{webarchive |url=https://web.archive.org/web/20070716105659/http://www.web3d.org/about/faq/#process-3 |date=July 16, 2007 }}.
