> The H-Anim WG meeting will be held with agenda items as follows:

>
>
> 1. Regular meeting times
>
> On August 7, Joe mentioned:
> >Let's meet every Wednesday.
> >Once a month is not enough for what we need to do.
>
> Based on Joe's request, the regular H-Anim meeting will be held every
> Wednesday at 5pm PDT.
> I may or may not be able to attend each week, due to the inflexibility
> of my work schedule. If I have no other meetings (e.g. Korea Chapter, CAD,

> All characters have been scaled with (scale 0.0225 0.0225 0.0225).
> All characters display properly in both BS Contact and Octaga.
> However, I still don't fully understand why we have to manually
> insert this scaling into the x3d files.

> 3. Resolution problem in wrl and x3d
>
> - resolution comparison between max, wrl, and x3d
> - Ideally, general graphics tools should generate wrl files with high
> resolution
> - or, wrl and x3d browsers should display them in high resolution
> - or, the wrl-to-x3d converter should insert the creaseAngle value?
>
> Should the wrl-to-x3d H-Anim conversion include a value for
> creaseAngle?
> How should this value be determined?

> 4. H-Anim behaviours
>
> - Questions about pitch, yaw, and roll among the behaviours
>
>
>
> 5. H-Anim presentations at the SC24 Sydney Meeting, August 26-30, 2013
>
> 1) H-Anim specification revision (NWIPs and WD Outlines) and current
> status of H-Anim developments, Myeong Won Lee
> 2) H-Anim facial animation, Jung-Ju Choi
> 3) H-Anim hands and feet animation, Kwan-Hee Yoo (Kwan-Hee Yoo will
> talk about this topic)
>
> 6. Scheduling next meeting
>
> We will skip next week’s meeting due to the SC24 Sydney meeting.
> Therefore, the next H-Anim WG meeting meeting will be held on (1st Wed)
