| summary |
The Australian branch of the SEED project created a new formalism for design spaces in which the fundamental structuring operator is information specificity, formally characterised as subsumption. Here design space navigation is composed as combinations of the primitive operators of resolution, unification, anti-unification, search, query and hysterical undo. The structures needed to support such a view are highly constrained in a mathematical sense and it is in these constraints that the problems for representation of geometry arise. The research challenge is to add the formal design space exploration constraints into an existing geometric representation scheme or alternatively to discover a new scheme in which the constraints are realized. Based on Typed Feature Structures (TFS), Geometric Typed Feature Structures (GTFS) are a representation scheme and method for performing the basic design space exploration operations on geometric objects. The crucial insight behind extending TFS to geometry is to discover useful algebraic structures of geometric objects affording the mathematics required of TFS. In this paper we describe Geometric Typed Feature Structures through one example of form: IOPSet. Our method of exposition is both mathematical and graphical: for each structure we will demonstrate both how it meets the necessary formal conditions as well as the sorts of form-sculpting operations it enables. An architectural example: insulated enclosure is used as a demonstration of subsumption operations over IOPSet. One alternative description of insulated enclosure using GTFS is also shown in the paper. |
