[Korea-chapter] [h-anim]_H-Anim WG meeting, June 5th, 5:00pm PDT (6th, 9:00am KST)

[Joe D Williams]

Hi All,
One additional suggestion on the goals, though maybe too detailed.
Whenever we mention processing captured data for application to the 
X3D HAnim Humanoid, please add something like "blending motions from 
different sources" to indicate we are aware that a desired net motion 
may be the result of several input parameters for motions and forces.

A simple use case is moving from independent Walk to Run animations 
and we wish for a smooth transition between the different animations 
in a realistric style. Typical is the sudden unsychronized motion due 
to the immediate transition between the stored routines we see in 
Nancy examples in the X3D HAnim example archives and others at:

http://www.hypermultimedia.com/x3d/hanim/JoeSkin4EXSPYRWRJK.x3dv

http://www.hypermultimedia.com/x3d/hanim/JoeSkin4EXSPYRWRJK.txt

This represents a Level1 skeleton (no skeleton geometry) with Level2 
skin.

where S=Stand,
  in Spec HAnim initial (default) pose before animation
  (except head is looking around);
P=major joints Pitch motion;
Y=major joints Yaw motion;
R=major joints Roll motion;
W=Walk motion derived from Nancy;
R=Run motion derived from Nancy;
J=Jump motion derived from Nancy;
K=Kick motion.

Please note the coordinate axis symbol in the head (actually child of 
skullbase) represents the default skeleton orientation for all joints 
prior to animation.

When we get the next pass on HAnim level1 skeleton example with 
illustrated Annex A Joint, Segment, and Site dimensions I wlll plug it 
into these animations without changing a line of user code in the 
skeleton as a simple test.

Anyway, this point of 'blending motions' is that the actual desired 
motion of the Humanoid may be the result of several inputs maybe with 
each independent of the others, maybe forward and reverse dynamics. 
This might be compared with multitexturing where the result is some 
certain blend algorithms using multiple independent textures. It has 
been shown, I think, that an author wants to be able to select, 
weight, blend, etc., to declare 'motion blending' effects to produce 
realistic motions, in order to sustain the abandonment of disbelief.
Thanks Again and Best Regards,
Joe
