Revision as of 19:01, 13 November 2013

Dick Puk, Myeong Won Lee and William Glascoe attended.

BVH to X3D Interpolators

  - Euler to quaternion conversion

Myeong sent an algorithm to convert Euler angles to a quaternion Don. There are several ways to convert. The conversion can be offline because it is not part of the browser. Don reminded us this conversion is an implementation issue only.

2. BVH unification

  - BVH to LOA1, 2 and 3

3. LOA 1, 2 and 3

  - Definition and naming 

Joe and Don are resolving joint names between the different LOAs.

  - Joint name: feature point, and landmark

4. Applications for LOA 1, 2 and 3

What is the best application for each level? Myeong thinks the medical applications warrants higher LOAs. William suggests the Use Case will dictate the LOA required. Dick agrees with William assertion. Don suggests we could had intermediate levels to map to some the Use Cases that are emerging in the market place. We are working on an intermediate LOA for hands, feet and facial animation. Myeong thinks we should make examples for LOA 2 and 3. Dick suggest we experiment with the same motion but use two LOAs. Do you always use a superset or allow additions to LOAs. Dick asserts it is a difference between specification and usage. How do you reconcile a situation of using a LOA3 (i.e., full up body ) but only animate a few of the joints? Dick wants to change the labels (title of Don's figure) specify level of articulation. Each level of articulation defines a "full" skeleton but higher levels resolve more joints (and segments or bones).


5. Scheduling next meeting

(3rd Wed) November 20th at 5:00pm PST (21st, 10:00am KST) or (1st Wed) December 4th at 5:00pm PST (5th, 10:00am KST)
