DESCRIPTION:“Find me sunny buildings near Hiroshima Station.”\nThis may
  sound easy for AI\, but handling spatial relationships and 3D information
  such as which way building surfaces face is not straightforward.\nThis ta
 lk presents a portable DuckDB-based approach to 3D city model search that 
 combines spatial\, semantic\, and geometric cues.
