[OSGeo-Discuss] Generalizing complex 3D vector polygon data

[Stefan Steiniger]

not that I know of any 3D FOSS.

however I know of research in Hannover (GER) by Frank Thiemann - german 
only webpage:
http://www.ikg.uni-hannover.de/de/forschung/projekte/3d-gebaeude-generalisierung/

and Potsdam (GER) group of Juergen Doellner:
http://www.matthias-trapp.de/
http://www.hpi.uni-potsdam.de/doellner/3dgi/index.html?L=1

so maybe look for publications of those people?
