Working Group Meeting Routine
Regular meetings are held monthly via teleconference. Participation is open to everyone via the Web3D teleconference line.
Non-members can request access information for this call, or Join Web3D for full member priveleges!
Meeting agenda and minutes are also distributed on the x3d-public@web3d.org mailing list and archived online.
Augmented Reality Roadmap for X3D
The Augmented Reality Roadmap for X3D is a description document charting shared strategies and our way forward.
History and Background Information
Web3D Consortium formed a special interest group on AR initiatives in July 2009 worked to help create the AR Technology Road Map.
Several Web3D Consortium member projects showcase the feasibility of AR in X3D, particularly X3DOM open source produced by Fraunhofer IGD.
- X3DOM can serve as an out of the box, standards-based solution for AR developers.
- X3D and X3DOM continue to improve scripting options for X3D with HTML5 and this has good promise for AR applications.
- X3DOM is being considered for potential standardization in a Mobile and/or Augmented Reality (AR) profile for X3D.
Our Web3D Korea Chapter members from ETRI are working on Mixed Reality visualization in X3D.
- The Consortium as been working closely within W3C HTML5 WG to align our standards for 3D visualization on the Web.
Additional details are available at:
Web3D Consortium is also engaged with the AR Standards Community, OGC, Khronos and W3C organizations for applying and adapting X3D.
- Web3D Consortium will be starting an AR working group in March 2011 to develop a roadmap for AR standardization. We encourage your participation.
- The technology discussions and meetings will be conducted publicly so that the widest possible comment and reaction can be considered from the Community. Feedback from this community will help X3D quickly and stably adopt new technologies to provide ongoing archival value for all 3D graphics.
- Meanwhile Web3D Members still retain important membership rights of proposing significant new technology and considering patented technologies within a "safe haven" prior to public release.
X3D Mobile Profile slideset from last summer's Mobile X3D ISO Workshop has also been linked: how Mobile, HTML5 and possibly Augmented Reality (AR) components can be aligned together.
Many new Web3D capabilities are becoming available. There has been no better time to discuss X3D technologies and also join the Web3D Consortium. Get involved in these early discussions to create the AR Technology Road Map. We look forward to your participation.
Developing X3D AR Specification - Proposals
The working group has reviewed the existing proposals and have summarized in Comparison of X3D AR Proposals. Based on this comparison, the working group is now preparing Plans for Merging X3D AR Proposals. The working group is looking for public feedback on the unified AR proposal that captures essential features for MR/AR visualization. The unified AR proposal for public review can be found here.
X3D Earth Working Group
The X3D Earth Working Group has expanded and refined a proposal by Dr. Myeong Won Lee for a new GpsSensor node. Due to several overlapping technical issues, the group has asked to collaborate with the Augmented Reality group on final design for this node.
Interoperability with other AR and Web Standards
Several discussions at the Web3D Conference, SIGGRAPH and ISO-SC24 meeting about the recent AR standards developments continue to improve and refine our strategy on interoperability with other standards.
Establishing common implementations and examples is important to demonstrate successful interoperable capabilities for the spec. Continued collaboration and reaching out to other AR standards groups is essential. Our common goal remains maximum interoperability with all Web standards.

- OGC ARML WG
- AR Standards Community Group
- ISO-SC24
- KHRONOS
The recent work in the Web3D MAR WG and the realization that the Current status of AR content models is not comprehensive, the ISO Standards Committee - SC24, which administers X3D review as an ISO standard has established a new Working Group for Augmented and Mixed Reality.
This Group conducted a survey of the current state of the art in AR/MR standardization, Here is a summary of the main findings.
- A need for making clear and precise definition of terms
- A need for a reference architecture with the following feature
- Separation of the content and browser/player/application
- Extendible and general enough to accommodate new future technologies (e.g. display devices, tracking algorithms, sensors, etc.)
- Defined at the right abstraction level to be platform/vendor independent
- Clear interface definition among the subsystems
- A proposal to develop a protocol between AR/MR engine and the object tracking/recognition subsystem independently from the algorithms used
- Reusing of existing standards as much as possible (see below)
- A content model based on the underlying reference architecture that is
- Comprehensive (e.g. scene/world model, interaction, rich augmentation methods and styling options, representation of extensive types of physical real world objects)
- A need for rich and sophisticated scene/world model
- X3D-based approach seems promising for providing a sophisticated world model (scene graph structure) and many media objects for augmentation. A proposal to extend X3D standards
- A need for representation of sensors and physical objects
- A proposal for a merged abstraction of physical objects and separate sensors as “objects with virtual sensors” and extend virtual sensors of X3D
- A need for sophisticated representation of “places of interests (POI)”
- A proposal to use and extend OGC/KML standards
- A need for extensive styling for 2D/3D information
- A proposal to use and extend HTML 5
- A need to abstract AR/MR interaction behaviors
- Complicated behaviors to be handled by scripts and DOM like approach
- A proposal to extend X3DOM for this purpose
- Needs other supporting functionalities
- Inclusion and specification of real world capture camera/sensors
- Moving texture/background functionality for video see through AR
- Handling of depth data and occlusion effects
- Specification of virtual/real light sources and rendering methods
Based on these findings the group proposes to derive a AR content model as an extension of a virtual world with provisions for representing the physically-sensed objects. The provisions refer to ways to specify the physical augmentation “targets” without specific sensor information and ways to (intuitively) tie or associate them to their virtual counterparts. This will result in vendor independence, use convenience and support for extensibility.
The ISO AR standardization proposal recommends
- Merging HTML and X3D (X3dom (Declarative 3D) for abstract content components for 2D and 3D Augmentation.
- The OGC and K-Mart for describing POIs and sensed physical objects.
- The Scripting approach for non-standard complex content behaviors and the use of remote cloud services.
Current technical work within the Web3D MAR WG includes harmonizing these proposals for best fitting AR capabilities into X3D scenes. This work will be formally written up as the Augmented Reality (AR) Component for the X3D Specification.
Participation and Liaisons
- Christine Perry's AR Standardization Community group
- Other partnerships can also be considered as appropriate.
Of interest is that Web3D Consortium Intellectual Property Rights (IPR) Policy insists on open, royalty free (RF) specifications. These coexist effectively with the Web Architecture and many different business models.
