Extensible 3D (X3D) Graphics is the royalty-free open standard for publishing, viewing and archiving interactive 3D models on the Web.

Numerous resources are available to support both X3D Graphics and its compatible predecessor, the Virtual Reality Modeling Language (VRML).

Books to top

Extensible 3D (X3D) Graphics

X3D Graphics is the international standard for real-time 3D communication.

Virtual Reality Modeling Language (VRML) 97 Books

VRML design began in 1994 and the language became a stable International Standard in 1997. Of interest: X3D is a third-generation design that is fully backwards-compatible with the second-generation VRML 97 standard. Thus all design guidelines and technical details in the following textbooks remains relevant.

Also available: VRML Resources.


Conformance Testing to top

There are three conformance test suites to help improve the quality of VRML and X3D players.

The Web3D Consortium offers compliance certification of this last suite. X3D Conformance Testing Program describes details.

The Web3D Consortium also supports the Conformance working group mailing list which includes list archives.

Of related interest: Quality Assurance (QA).


Conversions and Translation Tools to top

Numerous conversion tools are available for the various encodings of X3D and VRML.

X3D is a direct superset of VRML with three encodings: XML encoding (.x3d), Classic VRML encoding (.x3dv) and VRML97 encoding (.wrl). X3D is designed so that all three encodings are equivalent, you can choose to use any of them.

Converting X3D scenes to/from VRML (.wrl) also works well, since X3D is 3rd-generation VRML. The functionality provided by the VRML97 specification matches the X3D Immersive Profile.

  1. X3D players providing file-menu conversions (Save As) include BSContact, OctagaVS(pro), view3Dscene, and Xj3D.
  2. InstantReality X3D encoding converter is an online translator between ClassicVrml or XML (.wrl) encoding, and can also convert into X3DOM outputs (HTML5 or XHTML5). Free for non-commercial use.
  3. Xj3D Open Source for X3D/VRML97 includes command-line and file-menu X3D translators between all three encodings. Xj3D can also import Collada files.
  4. X3D-Edit exposes all of these Xj3D conversion capabilities via a conversion panel embedded under the X3D...Import and ...Export menus. X3D-Edit can further import, export and also edit, validate Collada files.
  5. Okino Polytrans is the premier industry translation tool that can convert many many different file formats (including Collada) to and from X3D, VRML97 and VRML 1.0. Their original 2002 press release describes the central value of the VRML/X3D scene graph as a detailed, extendable design used in the Okino converter architecture.
  6. XSLT Stylesheets convert .x3d scenes into alternate formats and encodings. These slidesets (and corresponding batch files) are bundled in X3D-Edit.
  7. BitManagement capabilities include BS Converter for 3ds max and BS Converter for Blender.
  8. NIST VRML to X3D Translator was originally written by Qiming Wang. An updated version of the source (and a .zip distribution) are maintained on SourceForge. The translator is also bundled in X3D-Edit under the X3D/Import/VRML97 menu.
  9. Blender provides excellent top-level import/export support, as described by Blender Model Export To X3D using X3D-Edit.
  10. Chisel VRML Optimisation Tool with new version autoinstaller and documentation provided by Halden Virtual Reality Centre. Originally built by Trapezium and maintained by NIST.
  11. XIOT X3D Input Output Tool library provides an open source generic C++ toolkit to import and export X3D in its different XML encodings: ASCII and binary. A special development was done to provide a Fast Infoset (FI) based X3D encoding.
  12. The SwirlX3D Translator is an enhanced version of the Viewer that permits Collada and 3DS files to be imported into VRML or X3D (Windows) (support).
  13. Vivaty has utilities and converters for Google Earth KML/Sketchup, Autodesk 3DS Max, Autodesk Maya, and Unreal. Vivaty Studio also includes Collada import.

Mobile Support to top

There is a mobile subset of the X3D vocabulary called the X3D Interactive Profile. Conversion tools are likely to emerge that can down-convert scenes using the X3D Immersive Profile or VRML97 for lightweight mobile and embedded applications.

There has been a lot of dialog about X3D Mixed and Augmented Reality (MAR) and whether a new X3D Mobile Profile is possible that harmonizes capabilities for lightweight scenes running with HTML5 on mobile devices, possibly including essential AR and GPS capabilities. How can such X3D capabilities best be aligned with HTML?

Join the X3D Graphics public mailing list to join the discussion and learn more.

PowerPoint Support to top

TODO: we need a more up-to-date way to install X3D plugins for PowerPoint.


Quality Assurance (QA) to top

Eliminating errors and warnings makes X3D content more portable and reliable.

The X3D Scene Authoring Hints: Validation describes DOCTYPE (DTD) and XML Schema validation of X3D scenes in detail.

The X3D Specifications are the authoritative reference for determining correctness of X3D scenes.

Of related interest: Conformance Testing.

Security to top

Open security by design, as specified by W3C's XML Security Recommendations, provides the strongest approach for secure Web documents used internationally on the Web.

The .x3d encoding is XML based, which means that the full power of Web Security can be applied to X3D Graphics models.

X3D model security supports multiple existing and emerging capabilities:

Most of these capabilities are demonstrated and formalized already. Several are already working-group efforts in progress. Therefore, this emerging combination of capabilities can be considered low risk, with high probability of full convergence eventually occurring.

X3D player and tool support for security:

The Web3D Consortium X3D Working Group participates in the W3C Security Activity and EXI Working Group to continue aligning X3D with ongoing developments.

Interested? Member participation is welcome.

Training and Tutorials to top

The annual Web3D Conference includes several excellent new tutorials each year. Now in it's 19th year, the conference is sponsored by ACM SIGGRAPH, Eurographics, and the Web3D Consortium.

The X3D for Web Authors textbook includes a comprehensive set of online examples, slidesets and videos. Coverage includes all of VRML  and the X3D Immersive Profile.

Additional training and tutorial resources include:


Videos to top

Numerous demonstration videos can be found online that show X3D models and applications in action.

The X3D for Web Authors book includes a full set of course video lessons for learning X3D.


Virtual Reality Modeling Language (VRML) 97 to top

VRML design began in 1994 and the language became a stable International Standard in 1997. VRML97 is fully compatible with X3D and is the basis of the ClassicVRML .x3d encoding.

Open Inventor to top

Open Inventor is an object-oriented 3D toolkit offering a comprehensive solution to interactive graphics programming problems. Of interest: the original VRML design was directly based on a competitive community selection of the Open Inventor .iv format as being the current "best of breed" for Web markup of scene graphs. This architectural design similarity provides fundamental common ground between Open Inventor, VRML97 and X3D.
