May 21th, 2014 at 5:00pm PDT, Agenda and Minutes
Attendees: Myeong Won Lee and William Glascoe Duration: 40 minutes
1. BVH conversion to X3D Interpolators
- Rotation order comparison between BVH and X3D - Rotation order in X3D SFRotation (x => y => z) ? - Rotation order in BVH (definition of rotation order)
2. H-Anim WG Meeting at SIGGRAPH
- August 14 (Thursday) 9:00-12:30 PDT ? (Tentative)
3. Scheduling next meeting:
June 4th (Wednesday) at 5:00pm PDT (5th, 9:00am KST)
We tested the converted file using our Suwon viewer and the BS viewer as follows:
(1) X3D H-Anim + BVH motion using our Suwon viewer
Our viewer displays the BVH kick motion of an X3D H-Anim character as in this video:

(2) BVH conversion into X3D Interpolators and the BS Contact Viewer
The BS Contact viewer displays the BVH kick motion, but with some slight differences. See the attached X3D file, including the converted interpolators.
(3) Comparison of BVH rotation and X3D SFRotation at each joint
The difference in motion comes from the difference in the order of rotation. The Suwon viewer shows the same result as in the BS viewer if the rotation order is changed to x,y,z.
WG members, please watch the *.AVI file Myeong Wong email us before the next meeting. The video shows Suwon's viewer on the left side, and BS Contact's viewer on the right side.
