The paper describes the parametric design, fabrication and construction of the Stone PolySphere, an installation that investigates the potential of digital fabrication applied to the stone industry. It is a lithic sphere with a diameter of 1.4 m, composed by a massive hemisphere below and a stereotomic hemisphere above. The prototype ideally summarizes, in a single object, the two big trends in stone architecture: the megaliths (below) and the stereotomic assemblies (above). The upper part is a micro-architecture that represents a domed space. The research also shows a new workflow for the realisation of non-reciprocal stereotomic geodesic assemblies, in which are used complex holed voussoirs generated by means of simple morphing operations and recursive subdivisions. The fabrication of the voussoirs consists in milling of several layers of stones glued together. The results are critically discussed, and the implications of the parametric design process are pointed out.

Abstract
The paper describes the parametric design, fabrication and construction of the Stone PolySphere, an installation that investigates the potential of digital fabrication applied to the stone industry. It is a lithic sphere with a diameter of 1.4 m, composed by a massive hemisphere below and a stereotomic hemisphere above. The prototype ideally summarizes, in a single object, the two big trends in stone architecture: the megaliths (below) and the stereotomic assemblies (above). The upper part is a micro-architecture that represents a domed space. The research also shows a new workflow for the realisation of non-reciprocal stereotomic geodesic assemblies, in which are used complex holed voussoirs generated by means of simple morphing operations and recursive subdivisions. The fabrication of the voussoirs consists in milling of several layers of stones glued together. The results are critically discussed, and the implications of the parametric design process are pointed out.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
