| Summary: | Especially in the field of numerical simulations, such as flow and acoustic simulations, the interest in using virtual 3D models to
optimize urban systems is increasing. The few instances in which simulations were already carried out in practice have been associated
with an extremely high manual and therefore uneconomical effort for the processing of models. Using different ways of capturing
models in Geographic Information System (GIS) and Computer Aided Engineering (CAE), increases the already very high complexity
of the processing. To obtain virtual 3D models suitable for simulation, we developed a tool for automatic processing with the goal to
establish ties between the world of GIS and CAE. In this paper we introduce a way to use Coons surfaces for the automatic processing
of building models in LoD2, and investigate ways to simplify LoD3 models in order to reduce unnecessary information for a numerical
simulation. |
