However, Gerry and I are not sure how to gather a log of the messages. (I am familiar with how to do this with Skype, for example, but not with webex.)<br>
My apologies.</p><p><br>>The H-Anim WG meeting will be held with agenda items as follows: <br>>Time: July 21 (Sun) 4:00-6:00pm <br>>Location: Hilton Anaheim Hotel and via Web conference (<a href="https://iso-meetings.webex.com" target="_blank">https://iso-meetings.webex.com</a>)<br>
>Attendees will be in person and via Web conference.<br>>1. Review of NWIP documents for the new H-Anim </p><p> </p><p>The following item has been added to the scope of the previous version:</p><p>- 11) 3D medical object for a humanoid: Humanoid models are useful in the medical field, including whole humanoids and partial humanoids (a segment or a partial segment), depending on the characteristics of the 3D medical application. 3D modeling and animation for medical objects should be defined. Volume rendering for medical applications is not included in this item.</p>
<p> </p><p>- Joe commented that the following items should be corrected because a skeletal humanoid can have 3D geometry with segment objects.</p><p>8) Skeletal humanoid: Skeletal humanoid has typically been represented as the hierarchical structure of a human figure with a simple geometry according to the relationship of joints. However, the representation should be enhanced to reference real skeletons with 3D geometric data to apply in medical and health fields. An enhanced definition for skeletal humanoid is necessary with skinned humanoid representation.</p>
<p> </p><p>- Based on Joe's comment, this item is amended to the following:</p><p>8) Skeletal humanoid: Skeletal humanoid has typically been represented as the hierarchical structure of a human figure with a simple geometry according to the relationship of joints. Real skeletons can be represented with 3D geometric data using segment objects. If we consider whole body and partial body in medical applications, an enhanced definition for skeletal humanoid is necessary with skinned humanoid representation.</p>
<p>Please send comments if this is not acceptable. </p><p>Joe, I have just read your e-mail with your concerns about skeletal and skinned humanoids.<br></p><p>If the above mentioned descriptions are not clear, I will update them again based on your recommendations, after taking a closer look.</p>
<p> </p><p>>2. Review of initial drafts for the WDs of the two parts (NWIP)<br>><br>>- Humanoid Animation - Architecture (Part 1)<br>>- Humanoid Animation - Motion Capture (Part 2)</p><p> </p><p>In Part 1 WD, ISO/IEC 19774 will be revised as follows:<br>
- Part 1 includes all the content of ISO/IEC 19774, and will be enhanced with details of existing concepts and new items.<br>- Existing concepts with be enhanced with further details and examples relating to recent work.<br>
- New items will be added with details and examples. </p><p> </p><p>Part 2 WD has been enhanced from the draft summary presented at previous Korea Chapter meetings and SC24 meetings.<br>All new items in the scope of the NWIP for Part 2 have been summarized. <br>
These will be enhanced with further explanations. </p><p> </p><p>>3. New proposals <br>><br>>- Facial animation, Prof. Jung-Ju Choi (Ajou University, Korea)<br>>- Hands and Feet animation, Prof. Kwan-Hee Yoo (Chungbuk National University, Korea)</p>
<p> </p><p>In Jung-Ju Choi's presentation, he mentioned that it is very difficult to define facial expression using the current H-Anim specification.<br>He focused on the following points:</p><p>- Because H-Anim is based on the skeleton hierarchy, and because facial animation is not relevant to the hierachy, it is very difficult to use H-Anim for facial expression.<br>
- Although displacer nodes can be used for facial expression, we would have to define numerous displacer nodes, perhaps hundreds or more for each facial expression.</p><p> </p><p>During Kwan-Hee Yoo's presentation, he mentioned that current H-Anim is lacking in representing hands and feet animation.<br>
He is considering gesture animation of hands and feet using H-Anim, but it is difficult to represent gesture because of the following points:</p><p>- Anatomically, the number of joints for hands and feet is lacking in the H-Anim specification. This is required to define them anatomically in detail.<br>
- He also thinks that the hierarchy of H-Anim makes gesture of hands and feet impossible because the motion of palm, sole, or top of foot does not depend on this hierarchy.<br></p><p>The joints of palm and foot are not represented with tree structure (tree structure), but rather formed in a cycle. </p>
<p>The two proposals will also be discussed further at the SC24 Sydney meeting to be held in the last week of August.<br>They will continue to develop standards in order to enhance the functionality of H-Anim.<br>These proposals will also be discussed further at upcoming H-Anim WG meetings. </p>
<p> </p><p>>4. H-Anim characters designed with general 3D tools </p><p>Due to time restrictions, this item could not been discussed at the meeting. However, the content is the same as was presented previously.<br>Demonstration of an H-Anim motion viewer with various H-Anim characters designed with a general 3D tool was scheduled.<br>
The method of designing an H-Anim character using a general 3D tool is included in the Annex of Part 2 WD. </p><p> </p><p>>5. Scheduling next meeting<br>>(1st Wed) August 7 at 5:00pm PDT (1st, 9:00am KST) or<br>>(3rd Mon) August 19 at 5:00pm PDT (3rd, 9:00am KST) </p>
<p> </p><p>The next H-Anim WG meeting will be held on August 7th at 5pm on the Web3D teleconference. </p><p>Thank you to all attendees, including those in person as well as those attending via Web conference.</p><p> </p><p>
