We first reviewed the slides and impressions of the TPAC meeting.

There were a number of possibilities presented here but little technical
detail.  Typically the term Canvas3D is used to indicate that a 3D API
might be available to HTML5 authors which can use either OpenGL or
DirectX underneath.

Some similar notions there to WebGL, which now has a compatibility layer for
DirectX (called Angel).

Discussion
- Declarative 3D ideas are interesting  to W3C members
- Tight integration with HTML5 desirable

History with W3C, WAI issues

Merits of Incubator group to establish requirements

I asked about apparent contradictions in XML3D slide about
X3D, response was to not to read too much into them.
Kristian said that the discussions on site noted there were some
differences between XML3D and X3D but that a number of similarities
exist.

Any incubator goals will have to reach clarity about the needed
requirements for declarative 3D representations on the web.
We agreed that there is a need to be very clear statement.
and development goals

We will have another teleconference on this topic next week,
same time Tuesday 8-9 pacific 5-6 Germany on Web3D teleconference
line.   Feedback and interest are welcome.

all the best, Don
