Surfaces: Concept, Design, Parametric Modeling and Prototyping

Our experiments are intended to refocus attention on the study of geometry, in particular on ruled surfaces, their possible discrete forms and/or development in the plane. The study of geometry is oriented to the concept, formal and expressive control, and built form. We begin with the critical analysis of the geometric shape, go through the problems of its virtual representation – also in parametric form – and finally transform it into a physical object with simple prototyping equipment that, on a small scale, reproduces a process repeatable at the large scale of architectural building. This is therefore a digital approach with roots in descriptive geometry. During our experimentation several models were realized, both parametric and physical. Today models can assist in experimental testing and are useful instruments for showing how the research was carried out.
