title Recognition of spatial grouping in rectangular arrangements
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary Rectangular arrangements are an efficient technique for generating an exhaustive catalogue of a class of designs. Moreover, they offer the possibility of retrieving designs from such a catalogue on the basis of geometric or topological features. The paper describes an extension of the possibilities of rectangular arrangements in indexing and retrieving catalogues of architectural floor plans through the recognition of spatial grouping. Using an adaptation of the chain code, each space in a shape arrangement is labeled in terms of its bilateral geometric relationships with contiguous spaces. This means that each space is maximally labeled as many times as the number of its contiguous spaces. The labels of a space are ordered on the basis of a priority list that reflects the stylistic preferences of the particular design class. Grouping of spaces uses the ordered space labels as criteria. The groups returned by this process agree with human intuitive perception of spatial grouping in the floor plan, as well as with expert architectural knowledge. For example, Palladian floor plans are consistently grouped into a central space group flanked by two symmetric space groups.
