Interesting. Do you have any idea how well this would work in 3D
space? I'm not sure what would be necessary to capture from this
library. The requirements (as I understood them) was to have
HTML-like capabilities in the contents of the label (I used HTML
so I wouldn't have to redevelop anything), a leader line of some
sort, and attachment to a piece of 3D geometry. <br>
<br>
What I gathered from a quick read-through of the documentation is
that the note is not HTML (but close), the subject is a portion of
a D3 graph, and the connection has lots of options. Given the
requirements, I think the only piece that offers includable
options is the connector. If I am wrong, please point that out.<br>

<b>Subject: </b>[x3d-public] Labels in 3D</p>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p>This is mostly for Nicholas and Vince who expressed an
interest in labeling things in 3D where the labels had the
capability of HTML to include various fonts, styles, text,
graphics, links, etc.</p>
<p>I would like to know if these types of labels meet your needs
or something else is needed.</p>
<p>This is using my testbed (XSeen). The example is at <a
href="http://realism.com/XSEEN/test/labels.html"
moz-do-not-send="true">http://realism.com/XSEEN/test/labels.html</a>.</p>
<p>All labels are done in HTML. The lines connecting the label
to the 3D object is done in 3D space. The labels retain their
screen position as the camera is moved. There are three types
of labels illustrated in the example -- fixed, relative, and
draggable. </p>
<p>The fixed label is attached to the "monster" The label line
tracks the local origin of the monster model. </p>
<p>The relative label maintains the initial relative screen
position to the projection of the (local) origin of the
object. The label moves as the object moves. This is
particularly obvious when looking from the side.</p>
<p>The last label (draggable) is attached to the torus. The user
may move the label to any position in the canvas (2D
projection of the 3D space). The leader line maintains the
connection from the label to the object. </p>
<p>There is preliminary documentation on the tag at <a
href="http://tools.realism.com/specification/xseen/language-definition/user-interactions/label"
moz-do-not-send="true">http://tools.realism.com/specification/xseen/language-definition/user-interactions/label</a></p>
<p>Caveats: <br>
1) The leader lines do not track well when the camera position
is changing nor when a draggable label is being moved.<br>
2) Things don't work as you would expect (or hope) for the
stereo camera.</p>
