Myeong-Won Lee, Yong-Sang Cho, Kwan Hee Yoo, Gun Lee, Anita Havele,
Dick Puk, Don Brutzman.

Gun Lee will soon be moving to University of Canterbury in New Zealand
as a postdoctoral researcher.  Congratulations!

Agenda and responses follow.

Our X3D + HTML5 page is

X3DOM is also well documented at http://x3dom.org

We added a link to Advanced Distributed Learning (ADL) as a
potential collaborator.  http://www.adlnet.gov

We added the following candidate outcomes and timeline items:


The Web3D Consortium is starting a new interest group: X3D and E-Learning. This will be in partnership with IMS Global Learning Consortium.

This group will enable the creation of Web-Enabled 3D content, tools and platforms for online e-learning.

We will collaboratively harmonize and integrate X3D Graphics content with other standards. We are also interested in possible collaboration with Advanced Distributed Learning (ADL).

Planned interest-group products include:

     * Collect requirements and describe typical Use Cases for applying 3D models in E-Learning
     * Produce a Recommended Best Practice for E-Learning with X3D Graphics
     * Produce several E-Learning Exemplars demonstrating E-Learning with X3D Graphics
           o Simple course lessons for teachers (preschool, K-12, higher education, and training)
           o Small report of 20-50 pages (and perhaps the Recommended Practice itself)
           o Full book production
     * If needed, recommend new nodes for X3D Specification. (None are yet identified.)


We hope to achieve these goals during a busy 18-month period of activity starting in April 2011.

Discussion items:

     * What should we plan for Web3D Conference 20-22 June 2011, Paris France
     * Can we plan for a session with SIGGRAPH Educators at SIGGRAPH 2011, 9-11 August in Vancouver Canada

we have multiple pilots under consideration under the Goals section

> We should also consider the following items.
> - international language fonts

X3D supports full internationalization of all Unicode fonts.

5.3.14 SFString and MFString

It also supports complete control over justification of
characters, both horizontal and vertical.

15.2.2 Text formatting

     * Introduction
     * Font family and style
     * Direction and justification
     * Language

Support for each ISO 3166 language is included:

15.4.1 FontStyle

15.4.2 Text

International characters can also be represented as Character
Entities in the .x3d XML encoding.

We will likely need to track what X3D browsers and players
support international fonts in their deployed software.
These are important capabilities and markets to support.

Encoding values for special characters in XML/HTML files are found under
Character entity references in HTML.

_X3D for Web Authors_ book and slideset include examples of using
internationalization (I18N) text in X3D.
(see slides 24-37).

Of related interest is that we have XML/HTML files for X3D Tooltips
in various languages that help explain the X3D language.

Tooltips are available in English, Chinese, French, German, Italian,
Portuguese and Spanish.  (There is also a draft submission in Korean
but the document has some validation difficulties that we need to fix.)

> - X3D viewer plugin for e-book

I think it would be good to list the desired attributes and
capabilities for an X3D viewer.  This would also be useful
to include (with descriptive explanations) in the Recommended Practice.

> The creation of an AR WG in SC24 could be a good start to standardizing AR in SC24,
> in addition to the Web3D AR WG.

This is a very interesting possibility which we discussed
in some detail.

> *3. Call for Participation for the Second Mobile Visual Content Study Group Workshop at the 2011 SC24 meeting*
> Date: August 21, 2011, 1pm - 5pm (on Sunday, the day before the 2011 SC24 meeting)
> Place: Alex Johnson Hotel, Rapid City, South Dakota, USA
> Extended abstracts (2 pages) due: May 31, 2011

> ISO/IEC JTC1 SC24 WG6 Convenor

Gerry Kim may be hosting an AR study group meeting that same day,
they are also considering those details.

> *4. New work items proposals*

Unfortunately we did not have time to discuss all of these things
buta few reactions follow.

> *1) Units specification (Myeong Won Lee)*
> Comments about the WDAM2 units statement were submitted to to the X3D WG.

> Therefore, I am OK with the X3D 3.3 version having the format as described in WDAM2, repeated below:
> In UNIT statement,

> 2) Projective texture mapping (Kwan-Hee Yoo)
> 3) Mixed reality visualization (Gun Lee)
> 4) CAD translation to X3D (Hyokwang Lee and Soonhung Han)

Details are updated on the wiki at

I still hope to discuss recent discussions with Mark Petit and
Christophe Mouton.

I'm wondering
- isn't this functionality mostly possible using existing X3D nodes?
- what do you think of the proposed NPS solution for interchangable
	H-Anim behaviors/bodies, online at
	HAnim Behavior Prototypes

Unfortunately the Web3D H-Anim working group is not currently
active, although the mailing list remains available.

> 6) Mobile X3D functions (Myeong Won Lee)
> 7) Geometric medical data (Kwan Hee Yoo)
> 8) X3D Digital Textbook (Kwan Hee Yoo)

This work be part of the E-Learning effort described in detail above?

> The following items were proposed as a result of the last meeting in Seoul
> (COEX Convention Center, December 14):
> *9) X3D GPS Interface (Myeong Won Lee)

This is under discussion by the X3D Earth working group
and the latest version is documented online at


We plan to revisit this topic in detail during our next teleconference
using the Web3D conference line on Wednesday 16 March at 0800 pacific.

> 10) A management system of security devices in 3D virtual space (Kwan-Hee Yoo)
> 11) A CCTV node for the CCTV control of virtual environment management systems (Hyun Woo Nam)*
> We would like to progress the definition of the above three items to be included in X3D.
> *5. Scheduling the next Korean chapter meetings*

We will split the AR and e-learning WG  into separate meetings:

March 9, 2011 (2nd Wed) at 5:10pm PST (Thursday at 10:10am Korea time): CAD WG
March 15, 2011 (3rd Tue) at 5:10pm PDT (Wednesday at 9:10am Korea time): AR
March 16, 2011 (3rd Wed) at 5:10pm PDT (Thursday at 9:10am Korea time):  e-Learning WG
April 6, 2011 (1st Wed) at 5:10pm PDT (Thursday at 9:10am Korea time): Korea chapter

Thanks everyone for another very productive meeting today.

all the best, Don
