Hi Philipp, I was also thinking to use Oulu dataset as reference. For proof of concept it would be enough to draw few buildings to correct place, or even just one. When theory is proofed to work, we can extend functionality to cover wider areas. Out setup is following: Postgresql with PostGIS extension. All data is stored to there. Then we have Geoserver with W3DS module. Plan is that Geoserver reads data from PostGIS and serves generated scenes to client. So for us it would be helpful if there would be ready xml3d test asset to be stored to our database. Since you have converted already Oulu 3D city model, would it be possible that you'd deliver couple XML3D houses to us? Or is it simple for us just to pick up house models from your repo? Then we could try to store them to our DB and try to use with GeoServer. I was also thinking to use OSM map for verification. It also gives nice extra touch for demo, so that there isn't just plain house models in the void :) Best regards, Sami On Wed, Sep 18, 2013 at 9:02 PM, Philipp Slusallek < Philipp.Slusallek at dfki.de> wrote: > Hi, > > Thanks for the feedback.
