Paper Abstract

This paper addresses the nature of events in 3D building models. Events are characterized by their structures, tenses and temporal attributes. They can be also distinguished in different types in terms of changes in geometries, attributes and textures. There are up to 13 temporal topologic relationships between two arbitrary events of different lifespan. These relationships may change with varying temporal resolutions. On the basis of the inherent dependence that exists between the spatial and temporal resolutions, a mathematical model is established to describe the relative significance of an event that occurs to geometries or façade textures. Since 3D buildings are the most important object type that characterizes the dynamic nature of a city, the investigations on their events can serve as a conceptual basis for modeling, acquisition, visualization and retrieval of a 4D virtual city environment.
