other operating systems can then view it.<br></blockquote><br></div>a new video will be uploaded soon, using a different video format, and<br>placed in the member/CAD/macro document directory above.

<br>am hoping that you can get permissions to<br>- put one or all examples under an open-source license, for example<br> <a href="http://www.web3d.org/x3d/content/examples/X3dResources.html#license" target="_blank">http://www.web3d.org/x3d/content/examples/X3dResources.html#license</a><br>
</blockquote><br></div>some of the examples can be released as open source, others have copyright<br>(or other) claims on them. the examples that free to share will be uploaded<br>to the macro-parametrics examples page.<br>
<br>Pranveer, if we need some examples to show certain translation capabilities,<br>or perhaps different CAD formats, then I recommend that you create a few new<br>examples (that have no legal encumbrances) and add those. It is important<br>
that we have enough examples that people can repeat this work. Any new CAD<br>examples would then also need to be converted using the macro-parametric<br>approach.<br><br>Eventually we will build a table that lists the various technical capabilities<br>
covered (corresponding to K models and C models). Table information can also<br>indicate which of various CAD formats are supported.
<div class="im"><br><br>
<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">- put the following versions online: original cad format, the macro<br> parametric XML, and the converted X3D<br>
- i hope to publish those examples as part of the X3D Basic Archives<br> <a href="http://www.web3d.org/x3d/content/examples/Basic" target="_blank">http://www.web3d.org/x3d/content/examples/Basic</a><br></blockquote>
<br></div>if you have one example already available, let's start with that.

<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">- if we can get the examples accomplished this week, we could add them<br> to the X3D Showcase DVD for SIGGRAPH ASIA next week<br>
</blockquote><br></div>showcase is too soon for this work, although maybe we can get 1-2 examples.<br>i remain willing to try if you can get some examples free.
<div class="im"><br><br>
<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">- i am interested in learning exactly how you used MeshLab and TETGEN<br> (both open source) to accomplish the conversions<br>

</blockquote><br></div>Pranveer will show me how to do these steps during my visit to KAIST<br>9-10 December. He can also present these on a CAD conference call at<br>a later date for others who want to learn how to do this.

<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">- it would also be good to post your XML schema, particularly since that<br> might be something that eventually goes into the X3D Specification<br>
</blockquote><br></div>A short description and link to the schema will be placed on the wiki page.<br><br>I will produce some corresponding schema documention using XML Spy, similar<br>to what we have produced for the X3D schemas. Examples:<br>

I could take the bus or train. What do you think?<br></blockquote><br></div>tbd. Byounghyun, might you be able to join us?
<div class="im"><br><br>
<blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">Tomorrow let us also talk about strategy for how this work might advance.<br>I think that providing a general solution for converting different CAD<br>
formats into X3D is very important. We should document this very well.<br>We should try to put the support into different X3D tools. I think it<br>is possible that this might even become part of the X3D Specification.<br>
Alternatively it might become something like an X3D Recommended Practice.<br>Certainly it will be very important for building realistic and large-scale<br>X3D worlds. There are probably also some excellent business opportunities<br>
for some of our Web3D member companies also.<br></blockquote><br></div>Unfortunately the precise status of our revised X3D CAD Component is<br>currently uncertain, Yumetech and EDF need to release an update to the<br>working group.<br>
<br>Based on discussions that you have had with Professor Han, I wish to<br>recommend that once we are able to repeat your work (by me and others)<br>then we start to document it as best makes sense in the form of an<br>
X3D Recommended Practice. As that matures, and as your full set of<br>
capabilities is completed/published/tested, then the X3D CAD working<br>group can consider whether that form remains satisfactory, or if we<br>should propose elevating it as a new contribution to the X3D Specification.<br>
<br>Thanks for reporting all this great progress. We don't need another<br>teleconference for a while. I look forward to seeing your latest/greatest<br>demonstrations while in Korea, and hope that other Web3D Korea Chapter<br>
members get to see them too.<br><br>Please continue to post improvements and additional details as appropriate<br>to your website and to the wiki. Take care Pranveer, see you soon.<br><br>References
