Then know about X3D!</p>
<p>3D is expensive to build and consume, and 3D standards can help to solve some issues was what Anita Havele – Executive Director, <a title="Web3D Consortium" href="http://www.web3d.org/realtime-3d/">Web3D Consortium</a> informed the audience at a session of <a href="http://www.opengeospatial.org/projects/groups/3dimwg">OGC 3D Information Management (3DIM) Domain Working Group</a> held at Mumbai. As a pert of her talk, she informed the audience on X3D framework.</p>
<p>X3D is a second generation VRML – a file format and run time architecture with 3 encodings and Multiple APIs. This provides a rendering engine to display your 3D data on web is royalty, free and is an Open ISO standard.</p>
<p><img title="Use of X3D for city modelling" src="http://www.web3d.org/realtime-3d/files/images/home/Banner_Planet9_nVidia.jpg?1294858574" alt="Use of X3D for city modelling" width="600" height="337" /></p>
<p><strong>X3D Earth for Geospatial Community</strong></p>
<p>While X3D can be used by many industries, in particular for the Geospatial / GIS community, this comes with <a href="http://www.web3d.org/realtime-3d/working-groups/x3d-earth">X3D Earth Specification</a> usable by governments, industry, scientists, academia, and the general public. Using X3D specifications, developers can easily create virtual globes and enable 3D data online. And the biggest advantage is unlike most of the 3D virtual globe environments you need to buy license for to enable your data online.</p>
<p><img title="X3D Virtual Globe Example" src="http://www.cadmaps.com/images/Fig1-x3dEarth.jpg" alt="X3D Virtual Globe Example" width="600" height="479" /></p>
<p><strong>The Challenge</strong></p>
<p>While X3D is free to develop and use, it mandates the client side apps to <a href="http://www.web3d.org/x3d/content/examples/X3dResources.html">download a plugin</a> to use the applications. To mitigate this challenge they are working on a on a framework called <a href="http://www.x3dom.org/">X3DOM</a> - pronounced X-Freedom, to provide native support in web browsers for rendering 3D content. So, in the near future, the 3D virtual globes, city models can run natively without any plugin needed on the client side.</p>
<p><strong>Examples of Geospatial projects using X3D</strong></p>
<p>While there are already some projects that have utilised this standard, a few key projects worth taking a note are below:</p>
<ul class='ulText'>

<td><hr><br>We build 3D Geo Models from clients' geological / geophysical interpretations; these can be as simple or complex as needed to convey a message. Usually that message is towards a non-technical audience, investors, AGMs.
At the end of it all we take that geometry and generate a web file (a significantly polygon-reduced version) that can be made available through any X3D enabled browser. An early coded interpretation can be seen @ http://www.geodyssey.ca/Moose/Moose_Cordel.xhtml .
X3D is a worthwhile effort and has come a long way in the past 10 years.<br></td>
