1. LOA2 and LOA3 H-Anim models

  - 10 Schematron errors from the validator in the LOA3 model. Don will review the reports and clarify the error messages. Don could not open either file with Instant Reality. 

2. SIGGRAPH Web3D standards draft meeting, August 9 (Sunday) at 1-5 pm

   - Waiting for reply from Anita who should facilitate with reserving a room for this meeting. Anita will arrange for the room at The Sheraton or a nearby conference hotel. WiFi, 

3. SFRotation interpolation between two SFRotation values

  - ex: if 10 SFRotations between 1 0 0 1.0 and 0 1 0 2.0. Don suggested using an Euler interpolation function. Don asked if MWL wants to compute the interpolation values herself. When you look at the "shortest path unit sphere" code examples you can back out the algorithm. Just look at the source code for the Open Source browsers (e.g., FreeWRL in C++) and search for the  implementation of the orientation interpolation node. Don suggested referencing the books Geometric Tools for Computer Graphics and Graphics Gems. MWL tried using X-axis, Y-axis, Z-axis independently but got poor results and rotation matrices didn't yield good results.

4. LOA3 inconsistency in the specification

89 joints/segments OR 94 joints/segments ?? ==> 94 joints/segments (7 facial joints/segments)

5. H-Anim motion capture (Part 2 WD)

6. Scheduling next meeting
