The algorithm is very efficient and though being an object space algorithm its run-time depends only on the complexity of the generated picture. The algorithm is recursive and uses extensively the coherence given by the adjacencies of the rooms within a building. Extensions to more complex models are considered.10.2312/eg.19831025
