What: 		Web3D HTML5 meeting February 23, 2010
present: 		John Stewart, Johannes Behr, Joe Williams, Don Brutzman,  
Anita Havelle, Leonard Daly.

Joe: Another message from Chris Marrin has been received on the html5- 
public list.

It would appear that Chris Marrin is trying to diminish some of the  
X3D arguments that are coming his way, by stating that:

"What I'm getting at here is that, if designed today, I think 3D for  
the web would be a much different and much simpler set of nodes than  
we see in X3D. That's why I say that WebGL is a good first step. It  
allows us to take the most appropriate steps toward the best 3D  


JohnS: Concern; we have lots of formats (jpg, pdf, etc) that can be  
used in html, or can run in standalone applications.  Why should 3D  
graphics be different? We should have a 3D graphics format that is not  
dependent on HTML technologies.

Don - Chris does not mention that all these things (CSS, DOM, etc)  
were discussed back when VRML/X3D was being defined, but were rejected.

Johannes; in General not a bad email… we should concentrate more on  
DOM integration issues and so on. In the last paragraph  he mentions  
stuff like mini-x3d - stripped down version of x3d.

Johannes - WebGL, no knowledge of image configuration - needed for  
proper layering so that one can properly push images on top of  
triangles. Ongoing discussion, will give an update for next week.

Johannes - Will respond to Chris Marrin's email, probably Wednesday.

ACTION:  Profile review for HTML X3D …. put mobile in there, too…. for  
Mobile workshop which is a month before SIGGRAPH.    (in Korea end of  
June timframe, before ISO meeting.)


John - Henri Sivonen - still have an outstanding email on the html5  
list; been busy and down with flu; anyone want to step up?

Don - will do right now.

(here is the reply: http://lists.w3.org/Archives/Public/public-html/2010Feb/0779.html)

Johannes; Have new BMW data demo - data from Bitmanagement, will need  
to ask for permission from Bitmanagement to see if we can put this  
data on-line.

Johannes: it interact through DOM and Scenegraph - showcase  
application prototypes.

Johannes: We have a couple of other showcases coming up.


Don; Reference: Neil Trevett at Khronos discussed  in reference to  
WebGL: "intend to write plugin for internet explorer"…

Johannes: then we are back to plugins again…might as well use plugins  
closer to desired functionality.

Johannes , O3D is probably better than WebGL in terms of performance.


Anita - I believe that we should focus on our message, lets not think  
about countering arguments, but advertise at what we are good at.

Anita; can the WIKI have a FAQ pointing to answers - it seems that we  
answer the same questions again and again. We should collect all the  
questions and put the answers in the FAQ.

ACTION: (repeat from last week)  we need to raise ISSUE;

ACTION: (repeat from last week) we should write a Web3D consortium  
members submission.

ACTION: JohnS - action send Anita source text files for hiperia 3d  
interview and 3d-test.com interview.

ACTION: Don, all, talk about timeframe for a "we support X3D in all  
browsers" advertising splash.
