[Korea-chapter] [X3D] Jan 2013 H-Anim Teleconference minutes

[Myeong Won Lee]

Thank you for the H-Anim WG minutes, William.
We discussed also the following responsible persons for all the items.
Please review this, and then add other persons appropriate for each
standardization item.
=============
1) Definition of a humanoid character model capable of generating motion
from captured motion data ==> Myeong/Joe
2) Definition of a humanoid character model capable of generating motion
using 3D scanner data ==> Myeong/William
3) Definition of a humanoid character model capable of generating motion
using a general motion definition such as keyframe, interpolation,
kinematics, and dynamics for human figures ==> Myeong/Joe
 4) Definition of motion parameters for transferring or exchanging motion
between different human character models ==> Myeong/Dick
5) Definition of a motion data interface for including motion data ==>
Myeong/Dick
 6) Definition of a motion viewer’s functionality ==> Myeong/Joe
7) Definition of interoperable human behavior prototypes  ==> Don/William
8) Definition of a 3D skinning interface ==> Joe
9) Definition of a recording interface for human motion such as gait  ==>
Don/William
 10) Provision for easier exchange of characters from design systems to
H-Anim systems. ==> Myeong/Joe
=============
Sincerely,

Myeong
