<P>The following are the agenda items for this week's Korea chapter meeting, November 11 (Wed) 5:10pm (PST)/November 12 (Thu) 10:10am (Korea). Please provide updates if any amendments or additions are noted. <BR> <BR>1. Projective Texture Mapping (Kwan Hee Yoo, Chungbuk National U.) <BR>>First, it is very important that these documents get posted to the website. <BR>><BR>...<BR>>2 questions: do your three proposed texture nodes work similarly to the <BR>>other X3D texture nodes with scope restricted to the geometry in the <BR>>same Shape node. For example: <BR>><BR>>Shape <BR>>Geometry node <BR>>Appearance <BR>>Material <BR>>Texture node <BR>><BR>>Hopefully the functionality DEF and USE are the same, for example <BR>>the same OrthoTexture might have a single DEF and 2 USE instances <BR>>to apply to the geometry found in 3 different Shape nodes. <BR>><BR>>(I think the answers are yes, but will let Kwanhee Yoo answer by email.) </P>
<P> </P>
<P>Kwan Hee will address updates.</P>
<P> </P>
<P>2. Mixed reality functions (Gun Lee, ETRI) </P>
<P>>> Gun has also defined the mixed reality functions as new nodes. <BR>>> It is necessary to review this and decide if these node definitions are <BR>>> appropriate for including the new functions in X3D. <BR>><BR>>Unfortunately Gun has not yet received comments about these nodes. <BR>>He would like to begin implementing them, likely using CyberX3D for C++. <BR>>http://www.cybergarage.org/vrml/cx3d/cx3dcc/index.html <BR>>He will contact the owner, Satoshi Konno in Tokyo. <BR>><BR>>Johannes and Yvonne, Fraunhofer has some similar nodes. Have you <BR>>you looked at this? Should there be a conference to discuss the <BR>>nodes before he implements? Please advise what you think. <BR>><BR>>Feedback from other browser implementers is welcome also. Please advise. <BR></P>
<P>Gun will address updates.</P>
<P> </P>
<P>3. Physical units specification (Myeong Won Lee, The University of Suwon)</P>
<P>The unit browser is being modified from the previous Physical node definition to the UNIT statements. There were contradictions in the email discussion of the X3D WG. We must decide amongst the following when determining which criteria should be applied in the implementation of the length units:<BR></P>
<P>(1) Length units are defined but do not affect the visual scene at all where there is no scaling. They transfer length units information only. In this case, we cannot compare differences in real length when two X3D objects designed separately are read into a scene using an inline node or by reading two X3D files together in a scene. There is no difference at all in the scene compared with no unit definition.<BR></P>
<P>(2) Length units are defined and do not scale objects when reading an X3D file, but relative scales are used when reading two units-specified X3D files together in a scene using inline nodes or by importing another unit X3D file. We must not scale objects when reading an X3D file because we cannot see the scaled objects of very large and small objects such as those of astronomical and microorganism size. It is desirable to use the same units in X3D files when it is necessary to have relative scales.<BR> <BR>I prefer the latter case (2). <BR> <BR>5. H-Anim motion data definition (Myeong Won Lee, The University of Suwon)</P>
<P>We define a Motion Capture node for H-Anim figures in order to transfer the data of moving H-Anim figures. It provides an interface between H-Anim data and motion capture data. An H-Anim viewer has been developed and continues to be updated. A summarized presentation file will be sent to X3D and H-Anim WGs soon. </P>
<P> </P>
<P>6. Mobile X3D functions (Myeong Won Lee, The University of Suwon) </P>
<P>A mobile X3D viewer is being developed according to the X3D interactive profile. As presented at the SC24 London meeting, the progressive mesh function is necessary for the server side program, but it seems unnecessary for the client side viewer. However, the GPS function is necessary to include in mobile X3D. Therefore, we propose a GPS node for mobile X3D.</P>
<P> </P>
<P>7. Web3D Korea Workshop, November 28, Seoul, Korea</P>
<P>We will have a Web 3D Standardization Workshop at Ewha Womans University, which is the venue of the conference held twice annually by the Korean Institute of Information Scientists and Engineers. Thirteen standardization items will be presented in the areas of X3D, CAD, education, medicine, GIS, Image, mobile, etc. </P>
<P> </P>
<P>8. Web3D Korea Chapter Seoul meeting, December 7-8, 2009, Seoul, Korea<BR>I will prepare the program and and inform everyone. </P>
<P> </P>
<P>9. Our next Korea chapter meeting is planned for: </P>
<P>November 25 (Wed) 5:10pm (PST) / November 26 (Thu) 10:10am (Korea), OR<BR>December 2 (Wed) 5:10pm (PST) / December 3 (Thu) 10:10am (Korea) </P>
<P> </P>
<P>Sincerely,</P>
