Hi Geoservers, 1. We have been working on an implementation of a W3DS server on top of Geoserver. We used the draft specification 0.4.0. It's only a draft, but we think that a working open source implementation can improve the draft and it might became a standard. The major motivation for this work is the HTML5 support in modern browsers, supporting X3D scenes (using the x3dom library). As far as we know, there are no other open source implementations of this service. We presented this service last week, in the Jornadas SIG Libre, in Girona.
2. All code was written on top of: Build Information Version 2.2-SNAPSHOT Subversion Revision 16244 Build Date 28-Mar-2012 12:54 GeoTools Version 8-SNAPSHOT (rev 37918) 3. Basically, we: 3.1 Registered another service (W3DS), implemented the operations GetCapabilities, GetScene, GetTile and GetFeatureInfo (not finished). 3.2 Updated Geotools to read 3D data from PostGIS 3.3 Updated Geotools to support 3D styles 3.4 Updates the web interface accordingly (in several places; we needed some specific options when publishing another 3D layer, beyond the 'data' and 'publish' tabs on the interface) 3.5 X3D is now supported as output. We also added a HTML5+X3D to enable direct preview on the browser (it's really nice to see the 3D data on browsers supporting WebGL) 4. We have the .war available, and the sources as well, from: http://3dwebgis.di.uminho.pt/sources/ We didn't create diffs from the sources. We just created a tgz file from the maven project, to allow people to read it, if necessary. 5. We also have some videos of the 3D data returned, available at: http://3dwebgis.di.uminho.pt/videos/ 6. We have a W3DS server up and running. Several requests[1] are at the end of the message, for testing. The result can be seen in WebGL compatible browsers (ie Firefox and Chrome). If the scene is not shown, try to force with 'Show all'. 6.1 Administration access to this server is available (just use the default geoserver admin password). 7. We have some more time and resources to continue this project, and we would like to integrate this W3DS service in the GeoServer trunk. 8. Questions: 8.1 Should W3DS be integrated in the truck? Or should it be an extension? 8.2 What is the best way to share and integrate the code developed for X3D? By opening several tickets? 9. Now that the service is running, we will start the documentation today :-) Any suggestions are very welcome.
