<div dir="auto">Thanks Andreas for sharing your scripts. We will give it a try asap. x3ddom is a great tool to create rapid, yet effective, 3d scenes and it's very welcome in the GIS arena ;)<div dir="auto"><br></div><div dir="auto">giovanni</div></div><div class="gmail_extra"><br><div class="gmail_quote">Il 27 mar 2017 16:11, "Andreas Plesch" <<a href="mailto:andreasplesch@gmail.com">andreasplesch@gmail.com</a>> ha scritto:<br type="attribution"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Hi Andreas,<br><br></div>I completely agree with your characterisation of the various 3d technologies. There is also webGL based Cesium which is higher level, still performant for somewhat larger scenes but tied to a specific, single, controlled implementation.<br><div><br><div><div class="gmail_extra"><div class="gmail_quote"><div class="quoted-text"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">
<p>* QGIS2threejs: uses WebGL. Goal is to publish a small scene to the web, independent from QGIS. QGIS is only used to prepare the scene. WebGLS/ThreeJS is quite a low-level technology compared to X3D</p>
<p>* X3D approach: more descriptive, human readable files. Similar to VRML or SVG. Goal ist also publication of smaller scenes to the web. X3D viewer may render either natively or through WebGL. X3D, compared to WebGL/Threejs lowers the barrier for script or XML people to further process the file after an export. The X3D concepts are easier to understand than raw WebGL.</p></div></blockquote></div><div>I am most familiar with X3D (having implemented most of the x3dom.js geospatial nodes) and want to focus on that since it promises longevity of content, even archival quality, including meta data capability.<br></div><div class="quoted-text"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">
<p>* qt53D: Based on OpenGL. could lead to a good integration into QGIS core. Not meant to be published to the web.</p></div></blockquote></div><div>This is probably what my question was aiming for. If there was a Qt53D based X3D browser then it would be possible to reuse that for QGIS3 integrated display. But I do not think there is. The closest would be probably Qt5 webkit with webgl and x3dom.js (or cobweb.js).<font color="#888888"><br><br></font></div><font color="#888888"><div>Andreas<br></div></font><div class="elided-text"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-size:10pt;font-family:Verdana,Geneva,sans-serif">
