<p>From reading H-Anim in detail (especially Part 1), it appears to
me that it is primarily doing two things <br>
</p>
<p>1) Defining animation with deformable skin<br>
2) Define bone definition and naming for humanoids. I noted that
humanoids (as defined in the spec 4.2.1) are not required to have
the normal human-like appendages (1 head, 2 arms, 2 legs)
[<a class="moz-txt-link-freetext" href="http://www.web3d.org/documents/specifications/19774-1/V2.0/HAnim/concepts.html#HAnimFiguresOverview">http://www.web3d.org/documents/specifications/19774-1/V2.0/HAnim/concepts.html#HAnimFiguresOverview</a>]</p>
<p>If X3D were to included deformable skin animation as an intrinsic
part of the X3D specification, would #1 be required?</p>
<p>If not, that leaves #2. It seems to me that this section is
optional based on references in the document to "are common",
"generally categorize", "may have", "model specific". It seems
that if one is modeling a human (not humanoid), then this
structure should be used; but if not a human, the the variations
are endless.</p>
<p>I think the document needs an improved focus and close work with
X3D WG to determine if deformable skin animation is to be included
in a future version of X3D.<br>
