The recent trend toward non-standard and free form architecture has generated a lot of debate among the Scientific Community. The reasons can be found in the renewed interest in organic shapes, in addition to recent and powerful capabilities of parametric platforms. In this regard, the Visual Programming Language (VPL) interface gives a high level of freedom and control for conceiving complex shapes.

The geometric problems in identifying a suitable shape have been addressed by relying on the study of Origami. The control of variable geometry has required the use of algorithmic models that ensure fast changes and free control of the model, besides a physical one made of rigid cardboard to simulate its rigid-foldability.

The aim of this research by Massimiliano Lo Turco, Louena Shtrepi, Ursula Zich, Arianna Astolfi and Matteo Botto Poaola is to present a prototype of an adaptive structure, with an acoustic application, to control sound quality and perception in spaces where this has a central role, such as theatres or concert halls.
