Thank you for the slideset, and the continuing excellent progress. Very impressive! Here are comments in writing from the teleconference.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>a. Slides 8-10: change "Proposed Nodes" to<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText> "Proposed Abstract Types and Nodes"<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>b. Slide 9, "X3DTextureProjectorNode" is colored red<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>c. Slides 11-14 would be a little more readable if the images were slightly smaller and in the lower right-hand corner. This would let the reader see the text at the same time as the image. You might also make the viewpoint a little closer to show better detail in the screenshot.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>d. Slide 16 needs a title.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>2. It is great to see that you have implemented this work in FreeWrl, and that you are next looking at X3DOM implementation.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>3. The X3D Specification editors are creating an X3D v4.0 specification document in the github site for Web3DConsortium. (This is only accessible to Web3D members.) We hope to have a section outline for Projective Texture Mapping (PTM) by the end of the year. If you want to use the existing Texturing Component as a template, to get started, feel free to do so. The important part is writing the first draft of the prose itself, so you do not have to worry about HTML or git or other editorial tasks.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><a href="http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/texturing.html"><span style='color:windowtext;text-decoration:none'>http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/components/texturing.html</span></a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>4. We hope that you are coordinating with the FreeWrl/FreeX3D team (using their public mailing list) to contribute to their open-source codebase.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText> <a href="http://freewrl.sourceforge.net"><span style='color:windowtext;text-decoration:none'>http://freewrl.sourceforge.net</span></a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>5. Can you please send or post your example files, shown in the slideset, for inclusion in Web3D's open-source X3D Example Archives. I hope to place them in version control, probably at an address such as<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText> <a href="http://www.web3d.org/x3d/content/examples/Basic/ProjectiveTextureMapping"><span style='color:windowtext;text-decoration:none'>http://www.web3d.org/x3d/content/examples/Basic/ProjectiveTextureMapping</span></a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>6. We would like to work next on XML Schema x3d-4.0.xsd and X3D DOCTYPE x3d-4.0.dtd which are draft (of course) and available online at<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText> <a href="http://www.web3d.org/specifications"><span style='color:windowtext;text-decoration:none'>http://www.web3d.org/specifications</span></a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>7. I hope to also have the following assets ready for your review at the upcoming meeting of the Korea Chapter in Seoul in mid January: X3D Tooltips, X3D Schematron, X3D Validator, X3D-Edit.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>8. Again thank you for this outstanding contribution to X3D capabilities from the Korea Chapter.
