<div>thanks for sharing your slides. They provide good

Thank you. Sorry for the delay - I had to catch up on some other
work. I also was considering your comments and how best to respond.<br>

<div>Some comments. While cobweb certainly is not used
widely it probably would have deserved mentioning in the
table of web technologies. Also, I think it is clear that
A-Frame is quite a bit ahead in terms of providing VR
capability, compared to others (unity may have something
functional as well). The slides, at least, did not seem to
make this obvious.</div>

I wanted to include applications/packages people were familiar with.
I was surprised at the lack of familiarity with X3DOM and A-Frame
from those in the audience. I was limited by space on the chart. I
would have listed Cobweb as open, declarative, and HTML with a
'Level of Use' as "low".<br>
<br>
A-Frame's VR capability (as all of its rendering capability) is
provided by Three.js. I know that Unreal has rather extensive VR
(Rift, Vive) headset capability. I believe that Unity does too.
Since the focus for this talk was on browser-based VR, I couldn't
spend the time addressing VR capabilities of these platforms.<br>

<div>Did you get feedback after your presentation ? Anything
you can share would be interesting.</div>

Nothing significant. There was more in discussions with other
attendees at the conference who did not see my presentation. I'll be
posting that over the next month or so.<br>

<div>The idea of combining of x3dom and A-Frame somehow is
interesting. I think it would boil down to implementing a
new x3d browser on top of A-Frame which may be quite
possible. I experimented by reimplementing IndexedFaceSet
and ElevationGrid in A-Frame and think that geometry and
material nodes could be quite straightforward. Not sure
about everything else but probably possible with a lot of
work. It also would mean having a SAI on top of the DOM
(as being manipulated by A-Frame and custom event
interfaces). Your presentation made a good argument that
there is a lot of value in having a wide set of
standardized capabilites.</div>

Personally, I think putting X3DOM on top of A-Frame is a bit like
inverting a pyramid. A-Frame (as defined, not extended) is a rather
limited-capability system. I think it would be much easier to put
A-Frame on top of X3DOM -- except the part with A-Frame extensions.
I think a better choice is to merge the two keeping the most
important capabilities of both. I am formulating some ideas on that.<br>

I presented at Silicon Valley VR Expo 2017 last week. The
title of the<br>
presentation was "Open Source Declarative VR/3D
Environment" where the<br>
focus was on enterprise requirements for VR. In the
presentation I<br>
looked at high level requirements and capabilities of a
declarative<br>
VR/3D/AR language, and compared those requirements to the
offerings from<br>
X3DOM and A-Frame. I found that neither application met
the<br>
requirements, but both are close enough that a merge would
get there.<br>
