FlexMaps 2.0

2020: New architectural challenges

The FlexMaps 2.0 is an interdisciplinary research project that builds on the previous experience, the FlexMaps Pavilion (link: http://vcg.isti.cnr.it/activities/pavilion/), in which the concept of FlexMaps has been successfully applied on architectural shapes. The FlexMaps 2.0 is a wooden structure, whose shape has been selected among a set of possible shapes to challenge the realization of a complex topology within a restricted indoor space. The selected anticlastic design geometry is a non-developable vaulted surface with three outer arch profiles and a central hole. The structure exploits the strengths of the FlexMaps systems of using mesostructured spiral geometry. Thus, it is possilbe to produce bespoke panels with variable stiffness by only modifying the geometrical parameters of the spiral without changing the material.

Statics Aware Grid Shells

2015: Polygonal architectural meshes with a stress-field-driven optimizations

This research proposes a framework for designing grid shells with an optimized polygonal tessellation. In contrast to most of the methods in this field that provide for shape alterations while preserving the mesh topology, this method preserves the initial continuous shape as a given input by the designer and alters the tessellation to improve the statics of the structure.

Position-based tensegrity design

2017: Automatic generation of stiff tensegrity structures

This work addresses the design of tensegrity structures, which are lightweight load-bearing assemblies entirely composed by only two types of elements: struts and cables. The form-finding of these structures is well known to be a complex problem, so that most of the existing design methods are based on the repetition of templated modules and are limited to simple shapes. Conversely, the present method creates free-form stable tensegrity configurations that satisfy both fabrication and geometric constraints.

The 'Adoration of the Magi' by Leonardo

2018: 3D Model for Diagnostic and Monitoring

The VC Lab participated at the diagnostic activity of the 'Adoration of the Magi' by Leonardo da Vinci, providing technical support to the Opificio delle Pietre Dure in Florence. The total surface of the famous unfinished artwork by Leonardo was acquired producing a single high-resolution 3D model. It was used to evaluate the conservation status of the painting and to measure the deformations of the ten wooden support. Furthermore, a previous 3D model created in 2002 was also integrated in the study developing a new approach to quantify the panel deformation along time by comparing the two 3D models. These results were presented for the first time at the International Art and Restoration Fair 2018 in Florence.

Etruscan tomb of Sigliano

2011-2013: 3D scanning of the remains of an etruscan tomb and the making of a video

The project, a collaboration between the Visual Computing Lab and the National Archaeological Museum of Umbria (Perugia), has been focused on an Etruscan burial site of Hellenistic age, discovered at the end of the XIX century in Sigliano-Val di Fosso (Perugia), and later destroyed. Its memory survives only in two archival documents and in some artefacts conserved at the National Archaeological Museum of Umbria. The fragmentation and heterogeneity of the materials, however, makes really difficult to provide a 'global' view over this burial site. Thus, we exploited the opportunities offered by digital media, to present to the public the monument as a whole, bringing back its original structures and objects.
