I’ve started a project able to generate 3D scenes from xml OSM data: osm2x3d. There is already a web service to generate x3d tiles.
Finally, the “Open Earth View” project aims to intensively exploit osm2x3d concept. It exploits x3dom js library: http://www.openearthview.net
Other features will be included: textures, skybox, svg for building floors, etc…
Currently, I’m alone on these projects.
Who could be interested to promote or join the team?
