Titel:
Implementing metric operators of a Spatial Query Language for 3D Building Models: Octree and B-Rep approaches 
Abstract:
A spatial query language for building information models enables the spatial analysis of buildings and the extraction of partial models that fulfill certain spatial constraints. Among other features, the developed spatial query language includes metric operators, i.e., operators that reflect distance relationships between spatial objects, such as mindist, maxdist, isCloser and isFarther. The paper presents formal definitions of the semantics of these operators by using point set theory notation....    »
