[Korea-chapter] [h-anim] H-Anim WG meeting, January 27th, 5:30pm PST (28th, 10:30am KST)

Tue Jan 29 12:21:55 PST 2013

Thanks, Dick.
I think it is time to do more than just suggest. I think we should 
have a set of normative internal and surface feature points done in 
the same way as for the joints and segments:
"standard' normative names and non-normative xyz dimensions. Then, the 
skin can be sized for a real human subject in the same way as the 
skeleton.
Yes, some work to define these points and hook them up for animation 
but this is what we need to complete h-anim2.
Joe

Hi, Joe --

Please note that the feature point names and locations in Annex B are 
only
suggested/recommended. You can verify this by looking at the title of 
the
Annex where it states that this is an "Informative" annex. If the 
names were
to be required, the Annex would have been "Normative". This is also 
true of
the levels in Annex A. A user of H-Anim is free to do other things.

  -- Dick

> Question 1: How were the feature points obtained?

I used the standard feature point names listed in the specification as 
a
start. The typical xyz locations are given in the VRML examples 
included in
the h-anim standard. I added some in between points in order to  fill 
in
some points for simple triangules. In some areas, like face we need 
more
points.

> Question 2: Are default points necessary?

The idea is that we specify 'standard' feature point names and 
'tyupical'
locations.

Of course the feature point locations will vary depending upon the
dimensions of the character being modelled.

Yes, just like the locations of the joints and length of segments is
adjusted for the actual human, the feature points are named locations 
that
may be varied depending upon the character being created.

Best Regards,
Joe
