Managing Complex Geometries through Rhinoceros: Voronoi cells

Abstract

This research describes the possibility of handling complex geometries through Rhinoceros, three-dimensional modeling software, by means of some parameterization blocks. More specifically, by processing programming codes in an internal Rhinoceros environment (Grasshopper), it is possible to parameterize geometries, allowing accurate and dynamic modeling. The geometry analyzed in the following discussion is an unconventional closed-cell structure. It is based on the application of Voronoi diagrams in the three-dimensional field, thus creating closed cells in a foamlike manner. The objective pursued is to further study the properties of such structures and possible applications, ranging from the automotive to the biomedical field. The possibility of modeling complex structures with easiness, combined with the possibility of realizing them through modern additive manufacturing techniques, leads to the development of new, unconventional materials with unique mechanical properties and fully customizable behavior.
