please be careful with responses]


Let me point out that our Community Group on "Declarative 3D for the
Web" has been set up for a while and is now also public (we originally
targeted an Incubator Group but then waited for the CGs to finally go


The aim is to extend HTML-5 such that we can include interactive 3D
graphics directly into the HTML document. We want to integrate as close
as possible to the existing Web standards, thus making it possible for
Web developers and users to easily and quickly make use of this
technology. This includes reusing the DOM for the scene graph, JS for
scripting, CSS for appearance, DOM events for input, etc.

Our XML3D (xml3d.org) and X3DOM (x3dom.org) by Fraunhofer IGD are
prototypes of what we have in mind. Both approaches will likely be
merged into a joint proposal (we actually have a common German project
to do so).

We had an unofficial kick-off at the Web3D conference in Paris a few
weeks ago and held a BOF at Siggraph, both with very good attandance.
Interestingly, Khronos (through Neil Trevett himself) was at both
meetings and will join and participate in the activities. We also had
someone from the Mozilla graphics team highly interested in setting up
some declarative layer for interactive 3D well above WebGL.

In separate projects we and the Fraunhofer team are using this already
also for AR applications. There is potential for some very obvious
synergy between the two groups for making AR work in the browser.
