[x3d-public] What is H-Anim?

[Leonard Daly]

 From reading H-Anim in detail (especially Part 1), it appears to me 
that it is primarily doing two things

1) Defining animation with deformable skin
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) 
[http://www.web3d.org/documents/specifications/19774-1/V2.0/HAnim/concepts.html#HAnimFiguresOverview]

If X3D were to included deformable skin animation as an intrinsic part 
of the X3D specification, would #1 be required?

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.

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.
