THREE-DIMENSIONAL TOPOLOGICAL MODELS OF BUILDINGS
A novel data structure for the topology of three-dimensional skeletons of buildings is presented. Each face of the skeleton is mapped to two half-faces in the topological model. The boundary of a half-face consists of a cycle of half-edges. Each edge is mapped to a bundle of half-edges containing one half-edge for each half-face at the edge. The bundle is decomposed into two dihedral cycles, one for each direction of the edge, containing the half-edges ordered according to dihedral angle. The topological model is constructed by partitioning three-dimensional space. Each partition subdivides a specified cell into two convex cells. Cells can be merged if the resulting cell is convex. The partition and merge operations are efficient because they are performed on a small subset of the elements of the model in the vicinity of the affected cell and are thus independent of the size of the model.
