Trondheim 3D demo in HD from Morten Jacobsen on Vimeo.
The movie above illustrates a preview of 3D Trondhiem in Norway, produced by C3.
The modelling process is automated, with the textures and mesh produced purely from imagery and not from the more traditional LiDAR approach. C3 are defiantly a company to watch out for in terms of 3D city models.
See http://kart.sesam.no/3d/ for a 3D flythough (Windows only at the moment) and http://www.c3technologies.com for more info.
