<p>(good meeting but limited minutes today, sorry)</p>

<p> </p>
<p>1. the plan listed here sounds great.</p>
<p> </p>
<p>Joe and I may send avatars to meetings on off days. 8)</p>
<p> </p>
<p>2. thanks for the wonderful model updates. astounding progress: Chul passed all validaton tests!! Wow!! Very impressive. 8)</p>
<p> </p>
<p>from discussion, here are some translator comments:</p>
<p> </p>
<p>- please use .x3d (not .X3D) as filename suffix</p>
<p>- please use X3D version="3.3"</p>
<p>- do not use rotation='0 0 0 0' since that is not a legal value</p>
<p>- please do not use DEF="hanim_etc." rather use character name DEF="Chul" etc. this will let authors copy them into one file.</p>
<p> </p>
<p>I will work on adding these to the model archive and provide further translator comments. Again thank you.</p>
<p> </p>
<p>3. not sure yet about the resolution problem... will think about it. wondering if some 3DS Max values or settings are not getting translated into X3D properly, perhaps a misunderstanding exists.</p>
<p> </p>
<p>creaseAngle discussion.. </p>
<p> </p>
<p>- it is an authoring choice. yes, sometimes tools offer this as a feature. it is hard to come up with a single rule that is always correct.</p>
<p> </p>
<p>- here is tooltip:</p>
<p> </p>
<p><a href="http://www.web3d.org/x3d/content/X3dTooltips.html#IndexedFaceSet" target="_blank">http://www.web3d.org/x3d/content/X3dTooltips.html#IndexedFaceSet</a></p>
<p><b><font color="black" size="1">creaseAngle</font></b> <b>[creaseAngle <a href="http://www.web3d.org/x3d/content/X3dTooltips.html#accessType" target="_blank">

creaseAngle defines angle (in radians) for determining whether adjacent polygons are drawn with sharp edges or smooth shading. If angle between normals of two adjacent polygons is less than creaseAngle, smooth shading is rendered across the shared line segment.
<br>
<font color="#447777"><b>Hint:</b></font> creaseAngle=0 means render all edges sharply, creaseAngle=3.14159 means render all edges smoothly.</p>

creaseAngle은 인접한 폴리곤이 날카로운 변두리 혹은 유연한 음영이 그려질때 각(라디안)을 정의 한다. 만약 두 인접한 폴리곤의 법선이 creaseAngle 보다 작다면, 유연한 음영은 공통의 라인 구분을 지나면서 표현한다 .
</p>
<p>Interchange profile <font color="#447777"><b>Hint:</b></font> only 0 and 긫 radians supported.
<br>
<font color="#447777"><b>Hint:</b></font> creaseAngle=0 은 모든 변두리를 예리하게 표현하는것을 의미하고, creaseAngle=3.14는 모든 변두리를 유연하게 표현하는것을 의미한다 .</p>
<p> </p>
<p>creaseAngle has nothing to do with the geometry, it changes how the geometry is drawn.</p>
<p> </p>
<p>example use in an H-Anim model: Jin might have creaseAngle='0' for showing every crease and fold in the Shape nodes for the shorts, then use creaseAngle='3.14159' for showing smooth legs.</p>
<p> </p>

<p> </p>
<p>4. human behaviors: we had a spirited discussion about names, confusion, roll/pitch/yaw, etc.</p>
<p> </p>
<p>Joes extension of some basic behaviors in the original NPS interface for Nancy are good. Even if some are confusable, they are valid X3D and legal authoring choices.</p>
<p> </p>
<p>Maybe we can improve them to avoid confusion... Joe I'm happy to help.</p>
<p> </p>
<p>William mentioned medical animations - this is a promising direction to explore.</p>
<p> </p>
<p>Congratulations everyone, we have begun working on the future challenges!</p>
<p> </p>
<p>5. Preparations for ISO Sydney meeting are well along and nearly complete.</p>
<p> </p>
<p>Kwan Hee Yoo has a wonderful slideset. He presented highlights to us. After the meeting, Myeong Won Lee will ensure that all presentation slidesets are on wiki.</p>
<p> </p>
<p>- lots of interesting discussion</p>
<p>- small note: your presentation .pdf slide 11 appears to be missing an image. perhaps slide 16 is missing an image too??</p>
<p>- of interest: slide 12 shows a foot with all bones labeled similarly to H-Anim specification, with annotations both in English and Korean... Kwan Hee Yoo is searching for Unicode translations in many different languages. that will let us automate skeleton
annotations for any language, both in tools and in H-Anim models themselves if desired.</p>
<p> </p>
<p>We communicated that full-fidelity models are very important, we are striving for anatomical correctness. Any subset models for animation must be strict subsets and not different. Then the H-Anim Level Of Articulation (LOA) models can be added cumulatively.</p>
<p> </p>
<p>It was not clear from this slideset what joints are missing from H-Anim 1.1 so please list the changes if possible.</p>
<p> </p>
<p>Thanks from everyone for the great work.</p>
<p> </p>
<p>6. We agreed to follow schedule listed below.</p>
<p> </p>
<p>Corrections to minutes are welcome.</p>

<p>The H-Anim WG meeting will be held with agenda items as follows: <br>
(Please add your agenda items that you would like to discuss) </p>
<p> </p>
</div><p><div class="im">1. Regular meeting times<br>
<br>
On August 7, Joe mentioned:<br>
>Let's meet every Wednesday.<br>
>Once a month is not enough for what we need to do.<br>
<br>
Based on Joe's request, the regular H-Anim meeting will be held every Wednesday at 5pm PDT.
<br>
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, AR, e-Learning) to attend in a given week, I will attend the H-Anim WG meeting.<br>
However, I encourage any H-Anim WG member to give prior notice and hold an H-Anim WG meeting whenever they feel it is necessary to speed up the progression of agenda items.
<br>

2. Th e 10 H-Anim game characters<div><div class="h5"><br>
<br>
- updated and uploaded to the H-Anim Wiki <br>
<br>
<a href="http://web3d.org/wiki/index.php/H-Anim#Resources" target="_blank">http://web3d.org/wiki/index.php/H-Anim#Resources</a><br>

<br>
All characters have been scaled with (scale 0.0225 0.0225 0.0225). <br>
All characters display properly in both BS Contact and Octaga. <br>
However, I still don't fully understand why we have to manually insert this scaling into the x3d files.
</div></div><p></p><div><div class="h5">
<p> - personalitiies requested by Don ==> under consideration. These will be fabricated as the characters were generated as generic avatars for a VR edutainment game with no distinct personality traits at the time of generation.
<br>
<br>
3. Resolution problem in wrl and x3d </p>
<p> - resolution comparison between max, wrl, and x3d <br>
- Ideally, general graphics tools should generate wrl files with high resolution
<br>
- or, wrl and x3d browsers should display them in high resolution <br>
- or, the wrl-to-x3d converter should insert the creaseAngle value? <br>
<br>
Should the wrl-to-x3d H-Anim conversion include a value for creaseAngle?<br>
How should this value be determined?<br>

4. H-Anim behaviours<br>
<br>
- Questions about pitch, yaw, and roll among the behaviours </p>
<p> </p>
<p>5. H-Anim presentations at the SC24 Sydney Meeting, August 26-30, 2013<br>
<br>
1) H-Anim specification revision (NWIPs and WD Outlines) and current status of H-Anim developments, Myeong Won Lee<br>
2) H-Anim facial animation, Jung-Ju Choi<br>
3) H-Anim hands and feet animation, Kwan-Hee Yoo (Kwan-Hee Yoo will talk about this topic)
<br>
<br>
6. Scheduling next meeting<br>
<br>
We will skip next week’s meeting due to the SC24 Sydney meeting. <br>
Therefore, the next H-Anim WG meeting meeting will be held on (1st Wed) September 4th at 5:00pm PDT (5th, 9:00am KST)</p>
