- Title
The Subsymmetry Analysis and Rule-Based Synthesis of John Portman's Midnight Sun.
- Authors
Ligler, Heather
- Abstract
The symmetry properties of John Portman's 1968 Midnight Sun cocktail bar are discussed in detail. A special emphasis is given to subsymmetry analysis to decompose the multiple layers of symmetry groups in the polyrhythmic design and to relate them to a foundational project in Portman's corpus, the 1964 house Entelechy I. This analysis informs a rule-based interpretation of the cocktail bar as a transformation of the hollow column prototype developed in Entelechy I. These findings are specified formally in the Midnight Sun grammar, a shape grammar implemented in a shape rewrite technology called Shape Machine. The implementation is then used to produce a series of variations featuring a range of symmetry groups. These outcomes and their implications for design generation as well as insights into Portman's design principles are discussed to conclude the paper.
