Dick Puk, Don Brutzman, William Glascoe, Myeong Won Lee, Joe Williams, and Prof. Jung-Ju Choi attended.

1. Facial animation using current H-Anim

Jung-Ju explained his proposal for facial animation. Joe Williams answered Jung-Ju's questions about the 

2. Restrictions on current H-Anim

Don explains how feature points are animated (via H-AnimSites) and how a comparison (coordinate interpolator of a mesh to see if a displacer is needed).

A prerequisite for coordinate interpolator is that every coordinate in the mesh must be animated.

  • In X3D, a CoordinateInterpolator can animate a mesh.
  • The red dots in the figure correspond to feature points
  • The number of black vertices might vary depending on an implementation

Joe's comments

A displacer's advantage is that you specify only the end value, not the initial value. A coordinate interpolator


There are animations using displacers. Joe recognizes this proposal is targeting an end point with a weight. In a way it works as an interpolator. Where do you get the source animations for facial expressions?
