In Cobweb, all X3D nodes are not DOM elements. I know this to be
the case because there are structural and node name conflicts with
HTML. So what is really being discussed here is Andreas' extension
to Cobweb. I feel that this is an important distinction to make
because someone getting just Cobweb would not have DOM access. I
encourage Cobweb to bring Andreas' extensions into its code.<br>
<br>
I agree that preprocessing X3D Script into HTML JavaScript is a
very viable path forward for legacy content, though I don't think
people will create new content in that manner. Making everything
look and act like HTML is the big goal and challenge.<br>
<br>
There are significant differences between the event models in DOM
and X3D. It is more than creation of new events or event handlers.<br>
<br>
The requirement to use Proxys needs to be very carefully
considered. For example Chrome only provides full support in V49
-- Released in March 2016. Many corporate environments lock down
their desktops and only slowly make changes. For example, how many
computers in the US and UK were hit by the WannaCrypt virus on
computers running Windows XP?<br>

<div dir="auto">Leonard, you can support the Script tag by
preprocessing it into JavaScript. You don't need eval, you
need something like browserify to preprocess your Scripts into
JavaScript scripts. What is left undone is the X3D event
model, work needs to be done there, but Andreas has shown a way
forward with the "outputchange" event I believe. Proxies are
used for JavaScript events.

harping on this because no one has yet shown me how this
is going to happen. <br>
On page 8 of the notes, item (6): "In principle, all
nodes in the standard, including scripts and prototypes,
can be supported."<br>
<br>
The X3D Standard specifies that the node is called
"Script" and contains children tags.<br>
HTML has a node called "script" without children tags.<br>
<br>
1) I do not see how the X3D Standard can be supported
"in principle" or "in practice" to meet the requirements
of the statement.<br>
<br>
2) HTML scripts are global and have access to the entire
DOM. #5 states that nodes appear in the DOM, so from an
HTML script I can modify all nodes in the DOM, including
X3D ones -- this would include X3D Script nodes if a way
was found to include it.<br>
<br>
3) All scripts in the HTML page occupy the same
namespace (that is global in scope). From an X3D Script
(if one was able to exists), I could access all parts of
the page, including other scripts, including possibly
non-X3D scripts.<br>
<br>
This is not integrating X3D into HTML; but elbowing
aside an X3D bubble within the HTML space. If X3D is
going to be integrated with the DOM, then really
integrate it with the environment. If not, then stop
using integrating and use something like "X3D space in
the HTML document"<br>

<div class="gmail_extra">Thanks for sharing this
thoughtful presentation. The sketch of an integrated
event model is particularly interesting and I may
redraw it in an attempt to learn about its workings.<br>
<br>
</div>
<div class="gmail_extra">The sketch is also
interesting as it must have come as something of a
relief to an audience listening to what must have
been the most text heavy presentation at a meeting
on 3d graphics ;)<br>
