| description | As there are numerous applications for 3D city models with a wide range of model requirements regarding geometric accuracy and
granularity, there is also a high demand for such models at different levels of detail (LOD). And although their reconstruction and
cartographic generalization has been widely studied, particularly with regard to 3D building models, their encoding for a progressive
storage and transmission is up to now not profoundly explored and sufficiently solved. Most often building models at different LODs
are considered as discrete entities that are not related to each other. In this paper we present a progressive encoding and transmission
scheme for 3D building models that is easy to understand and implement for the end user as well as flexible and extensible for the
model producer. The progressive scheme is based on string grammars and describes a sequence of successive LODs as a dynamic set
of production rules. In order to restrict the effects of LOD changes on a local range of the progressive string representation, we use a
solid modelling approach based on planar half-spaces to construct 3D buildings. The generation of such progressive string grammars
is shown and examples are given. |
