||Medial Representations for driving the Architectural Creative Process
||International Architecture Symposium, Barcelona, April 2008
||Medial representations of shape provide a powerful framework for the analysis and genesis of architectural forms,layouts, landscapes, cityscapes. In this paper we explore their potential use in driving the architectural creative process for 2D and 3D applications. We consider both the aspects of (i) the analysis of exisiting architectural layouts, and (ii) the genesis of novel ones.
The archetypal medial representation of shape is the “medial axis” of Harry Blum (circa 1960). Boundary
elements, the outline samples of the objects of interest, are used as the source of a wavefront propagation, for
which the quenching points constitute axial symmetries. In 2D layout applications the resulting medial axis (MA) takes the form of a graph which unites geometry and topology of the objects and the field they occupy in one single framework.
In the following we first survey the topic of shape representation via medial structures and consider their
specific use in architectural analysis and genesis. We then report of early works in extending such ideas for novel
applications relevant to architecture.
