<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.). <br>
</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.<br>
