<P>Myeong Won Lee (Chair), Dick Puk, Joe Williams and William Glascoe (Co-Chair) teleconferenced from 2000 - 2230 hrs Eastern, Thursday, 03 Jan 2013 </P>
<P>Myeong discussed her group's content creation process. They use the skelton and skin together in their process.<BR> <BR>Joe described how a couple of the H-Anim specification nodes (skin coord index and skin coord weight) worked. We referenced a H-Anim file Joe provided with a lot of vertices in the skin that are all are bounded to a joint that uses a displacer for moving skin independent of joint motion.<BR> <BR>Joe discussed the Level of Articulation 3 (LOA3) skelton's joints movement and its design rationale. We referred to the skin animation in the same H-Anim file he provided (the running human) to illustrate his points about joint translation and rotation.<BR> <BR>Joe discussed which nodes his used in the H-Anim file we referenced. He shared his observations of others' H-Anim files where their skin wasn't built in skelton space. They were built in "skin space". Joe reminded us the skin that Sandy Ressler built is 40 times larger than a normal adult (i.e., an 80-meter tall human). There are 30,000 vertices used in that character--too many to connect. The only way to use it is to bind to the joints some how. </P>
<P>Binding textured geometry to the segments. But we want a realistic moving skin. In the skin node, ...face set... Most of these are called "skull tip". </P>
<P>That other skelton is approximate 1.77 meters tall. Joe thinks it's important to build a skin in skelton space to avoid a lot of transformations. </P>
<P>If Joe's skin points correspond to his feature points then he has a realistic character.<BR> <BR>Joe's approach is close to MoCap. Some of the MoCap he has seen doesn't worry about the skin. Authors create the skelton and put any skin on it they want. </P>
<P>Willian discussed his relationship with Roger Nelson of motionwerx and suggested Roger and Joe has a conversation about our NWIP.<BR> <BR>We assigned members to the NWIP line items and discussed our strategy for soliciting Best Practices from technical sources. <BR> <BR>The meeting adjourned at 2230.<BR></P></DIV></DIV></DIV></DIV>_______________________________________________<BR>X3d mailing list<BR><A href="mailto:X3d@web3d.org" target=_blank>X3d@web3d.org</A><BR><A href="http://web3d.org/mailman/listinfo/x3d_web3d.org" target=_blank>http://web3d.org/mailman/listinfo/x3d_web3d.org</A><BR><BR></BLOCKQUOTE></DIV><SPAN class=HOEnZb><FONT color=#888888><BR><BR clear=all><BR></FONT></SPAN></DIV></BLOCKQUOTE>
