This is an opportunity to start with a successful yet static model with overlaid authoring interactivity, including some binaries of big data, to be moved into x3d space, into a more complete authoring environment, provide some animations and improved, maybe even integral rather than overlaid, interactive features.<u style="font-family:"Courier New""></u><u style="font-family:"Courier New""></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:10pt;font-family:"Courier New""><u style="font-family:"Courier New""></u> <u style="font-family:"Courier New""></u></span></p><p class="MsoNormal" style="text-align:justify"><span style="font-size:10pt;font-family:"Courier New"">So, all we need is that graph that shows matching (direct usability) between .glb fields and x3d fields.
