Standards-track OPEN SKINS for HAnim

X3D "Standard" Skins

HAnim Refinement for 'free' and 'standard'
HAnim resizable skin(s)
that associate with the various LOA skeletons.

X3D HAnim binding details start with providing three closely related 
items:

(1) a continous-mesh representing a humanoid skin surface that is 
drawn:

 * facing +z toward the default viewpoint

 * in tight 'A' pose
    (see HAnim skeleton
default neutral "Relaxed Attention" pose
prior to animation)
 * in typical X3D HAnim humanoid space (C-space),
 * user coordinates in meters,
 * 0 0 0 origin between the feet,
   gaze +z,
   right=-x, front=+z,
   min y=0 at bottom of feet as standing on surface y=0 plane,
   max y at skull-tip site,
   root x and z at/near 0,
    (see supplied skeleton dimensions, and Annex A and B)
 * user code point index with respect to HAnim skeleton hierarchy 
diagram

The intent is stable resizable skins. Group sets of vertices that are 
bound to individual and multiple Joint nodes and/or to Displacer 
nodes, along with basic site and feature point vertices, for easy 
identification and interaction, but basically index 0 - top of head, 
skull tip.

These geometries will be used as an example 'standard' HAnim Humanoid 
skin field.

(2) Each skin includes a mapped texture that identifies by mark the 
set of surface Site (Annex A) and surface feature point (Annex B) 
locations.

This texture will be applied to the skin using a 'standard' texture 
mapping that would allow a easy to adapt texture to represent humanoid 
features use this 'standard' texturesimple, realistic-looking 2D or 3D 
texture.

(3) All X3D HAnim Joint skinCoordIndex[] and skinCoordWeight[] data 
for each particular skin binding to matching skeleton LOA.

This data binds deformation animation of the skin. Specific tests wil 
be generated by the user community to produce consensus on skin vertex 
points along with joint(s) bindings and weithts.

Together these three items -- skins, mapped textures, and binding 
index and weight data -- are used as reference LOA examples to support 
HAnim and X3D implementations. Finally, these sets will provide a 
reasonable start for anyone wishing to learn Human character animation 
fundamental and advanced topics.

Thanks and Best,
Joe

Hi John~!

it has been such a packed weekend
and certainly the week will bring more ideas and surprises !;;->

but there is this community-generated wish list:

further ideas and discussion welcome as we continue to check off key 
pieces
in X3D integration and adoption!!!


with best regards,
