[Korea-chapter] [h-anim] composable behaviors, animations, sequencers

Sun Jul 14 20:16:02 PDT 2013

Dear Joe,

I have attached our first H-Anim character named "1Jin".
An image file for its texture is also included.
Its resolution looks not good in the BS Contact viewer, but very good in
other tools.
We must figure out the difference of the resolution.
We used IndexedFaceSet for the geomery of each segment per joint.

Sincerely,

Myeong
