HTML defines may convenience tags. While it is not strictly
necessary to have something like "table" and all of its children
tags, it does make displaying a table much easier. It would
certainly be possible to have something like<br>
<br>
<tt> :</tt><tt><br>
</tt><tt><div id='x3d'></tt><tt><br>
</tt><tt> <div id='scene'></tt><tt><br>
</tt><tt> <div id='t1' class='transform'></tt><tt><br>
</tt><tt> <div id='s1' class='geometry-box appearance-sign
appearance-limit...'></div></tt><tt><br>
</tt><tt> </div></tt><tt><br>
</tt><tt>
</div></tt><tt><br>
</tt><tt></div></tt><tt><br>
</tt><tt>
:</tt><tt><br>
</tt><tt>
</tt><br>
It does get difficult to understand and it is possible that each
developer would have their own definitions of #x3d, #scene,
.transform, .geometry-box, etc.<br>
<br>
I did think about this style, but decided that readability of
content superseded the abstraction of all elements and the complete
separation of content and style.<br>

<b>Subject: </b>[x3d-public] Appearance of Geometry in HTML</p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p>If HTML/CSS world, the appearance of an element is (ideally)
set in the appropriate style definitions for the element using
a combinations of classes, ids, tags, and hierarchy. This
includes it's edge effects (border style, corner rounding,
padding) and internal appearance (color, background color,
gradients, fonts, etc.). </p>
<p>Using the same environment (HTML/CSS) and adding the 3D
dimension (and maybe second cameras, markers, etc.) should the
appearance of objects (geometry) be controlled by the
appropriate style definitions? Why or why not?</p>
<p>If CSS+1D style definitions are used, then there is no need
to any appearance nodes (Material, ImageTxture, etc.). It
might be done as <Shape class='sign
speedLimit'><IndexedFaceSet ...></Shape>. The
classes would add the black border, yellow background, text
color, etc.</p>
<p>The disadvantage is that some geometries may be require an
extremely complex vertex (or face) assignment for this to be
practical.</p>
<p>This method does align nicely with HTML and allows HTML tools
and concepts to be carried over to 3D/VR/AR/xR.</p>
