Integrating Current Weather Effects into Urban Visualization

General interest in visualizations of digital 3D city models is growing rapidly, and several applications are available that display such models realistically. Many authors have emphasized the importance of realistic illumination for computer generated images, and this applies especially to 3D city visualization. However, current 3D city visualization applications rarely implement techniques for achieving realistic illumination, in particular the effects caused by current weather. At most, some geospatial visualization systems render artificial skies – sometimes with a georeferenced determination of the sun position – to give the user the notion of a real sky.
