<p>I appreciate your confidence in me, but I feel that I
would make a mess of it. Plus, if I can't read
existing standards, I probably can't figure out how to
improve them either.<o:p></o:p></p>
<p>I have similar problems with videos, TV episodes,
books, etc. I've been working on doing better with
videos, but it seems that YouTube makes me angry now.<o:p></o:p></p>
<p>For some reason, my ability to email people remains.
I don't know if I comprehend things too well in
emails.<o:p></o:p></p>
<p>I feel it's best to stick with my strong points in
bug finding, problem solving and creativity. I am not
sure if there's a place for that in Web3D/X3D.<o:p></o:p></p>
<p>I totally understand that X_ITE supports script
<field>s, but I don't know if script
<field>'s are required to be supported by the
standard.<o:p></o:p></p>
<p>I think the main sticking point is that HTML does not
support script <field>'s, so neither does X3D4?
But somehow, X_ITE supports <field>s in
scripts, and does DOM as well, via Andreas'
extension. It would seem that X3DOM could support
scripts given some effort. When I tried, I ran up
against <field>'s not being supported, so I
bailed. But perhaps someone with a bit more
persistence could get past that, IDK.<o:p></o:p></p>
<p>Integrating Protos and Scripts still seems to be an
unsolved problem in X3DOM? Is my effort the only one
that actually has some modicum of success (with some
of my own files)? If we start somewhere, should we
start with my effort, or X_ITE? Or another path?<o:p></o:p></p>
<p>I opened email to report a possible misunderstanding
in x3d.py. I'll put that in another email.<o:p></o:p></p>
<p>Thanks!<o:p></o:p></p>

<p class="MsoNormal">Hi John,<o:p></o:p></p>
<p class="MsoNormal">Scripts are completely
involved in the x3d sai event model. A script
must receive an event to begin execution and
then it is like an ’external’ in that when the
script begins it essentially acts like a
beginUpdate and when it completes it
essentially gets an endUpdate and all outputs
are sent with the same time stamp as kicked
off the script. Think of it as script is like
any other node that can receive and send
events. Only exception is, I think, that a
script directOut does not initiate a new
cascade<o:p></o:p></p>
