| dc.description.abstract | In this paper we address the problem of geometric interference in architectural databases, that arises when different architecture and structural engineering teams integrate their designs into a common 3D scene. By analysing in detail the current work practices, we have modelled a design verification matrix for interference cheking, between architectural (wall, window and door openning, etc) and structural design elements (column, beam, roof slab, etc). In our novel algorithm, we’ve implemented a Binary Space Partitioning (BSP) scheme for all the scene elements, along with several boolean operators that apply to the BSP tree. Every interference can be expressed as a boolean equation that must hold true. Each pair of architectural and structural elements, from the verification matrix, is substituted into the relevant equations and, if a false result is obtained, an inconsistency is visualy signalled and can be discussed at a distance, using our own multi-user 3D virtual environment. | en_US |
