I think that the WG needs to seriously consider the usefulness of
all nodes in the current version with the intent of deprecating a
number of them. Many of these nodes were developed as a means to
make it easier to hand-code models or scenes. I feel that is not
needed anymore because there are open-source modeling tools (e.g.,
Blender) that handle all of those functions. I feel it is a
significant disservice to the community to continue with a very
expansive set of nodes that are not used much. I would also
recommend that V4 profiles be defined that do not include those
nodes so people developing V4 browsers are not required to support
them. It would also be necessary to have a conversion tool that
updates content using those nodes to profiles that do not use (or
support) them.,<br>
<br>
On my (incomplete) short list:<br>
<ul>
<li>Extrusion</li>
<li>ElevationGrid (I know that this provides "gravity" for WALK
mode -- a replacement capability would need to be provided)<br>
</li>
<li>Text</li>
<li>FontStyle</li>
<li>Layout (I think this has already been mentioned)</li>
</ul>
<p>Nodes (or node categories) I think need particular investigation
<br>
</p>
<ul>
<li>Chaser/Damper/Follower (there are some valuable features here,
but perhaps the capability can be improved)<br>
</li>
<li>Some of Triangle*Set</li>
<li>2D Geometry (can SVG be used instead?)</li>
</ul>
<p></p>
<br>
My goal in this is to identify the nodes that are important; those
that are used not just for educational purposes; and those that look
nice, but are not used. I don't want to remove valuable
capabilities, but to allow developers to be able to focus on their
problem without getting distracted by unnecessary or duplicative
capabilities. At this time, I am not advocating the removal of those
nodes because the long-term and archival use needs to be considered.
