[70] Topological Queries in a Space Partitioning Model

Paper Description extracted from PDF · abstract · 138 words

A modern building model is usually digital (BIM) and contains the geometry of the elements and spaces. The topological relationships of their elements, on the other hand, are often insufficiently described. However, many civil engineering applications do rely on the topological relationships between modeled elements. Two examples for that being energy modeling and the computer assisted navigation through indoor spaces. This paper investigates how topological queries can be run on an exemplary polyhedral space partitioning model. Therefore, a brief introduction to the principles of polyhedral space partitioning is presented. Current research approaches for topological models, spatial information and graph-based building models are reviewed. Topological queries are presented that derive neighboring relations from the investigated polyhedral space partitioning model. These queries are subsequently used deriving and visualization graph models that represent the full topology of the space partitioning model.
