Attendees: Myeong Won Lee, Richard Puk, William Glascoe

Agenda: 1. LOA pictures updated

   - Facial joints

Myeong asked a few questions about skin, displacer objects, H-Anim feature point names, and facial joint usage.

- In the Humanoid interface, both segments and skins are defined. Do both have geometry? Are both needed for a human model, or optional? - What difference is between displacer nodes and skins? - How to know boundary between segments and/or between skins? Because skins will have to be tranformed when animated. The boundary must have the same geometry between segments during animation. - The Humanoid interface does not include displacer nodes. Does this mean that skins are displacer nodes?

2. H-Anim LOA3 facial problem

From Joe's message dated May 14, There are only two facial joints defined, eyeball joints, from the skull base..

Reference: Table 4.4 Face Joint object names, 4.9.5 Hierarchy http://www.web3d.org/documents/specifications/19774/V1.0/index.html

The basic design for X3D facial animation uses Displacer nodes which animate either geometry in the Humanoid skin field, or geometry of segments in the skeleton field. The Displacer operates by controlling movement of each specific vertex over a specified range in skin space.

3. Skin & segments review
