Origami Design Strategies for Architects and Designers. Analysis and Design of Folded Surfaces Through Algorithmic Modelling
No full textBoth in the field of manufacturing and architecture, the art of paper folding (origami) is often taken as a reference for its kinetic proprieties and its elegant appearance.
Dynamic facades, fast deployment structures, temporary shelters, portable furniture, and retractile roofs, are only a few of a vast variety of examples that can take advantage of theories proper of origami art.
However, the available applications typically used by architects and designers are usually missing tools to aid the design of foldable mechanisms.
Thus, this book addresses different strategies to narrow the gap between the potentialities of this discipline and the limits of the most used informatics tools, by proposing a synthetic parametric constructive approach, which allows designers with no background in math and scripting to deal with design problems typical of origami, such as folding simulations, rigid foldability, one degree of freedom motion, origami thickening, developability checking and more
La fotomodellazione per il rilievo architettonico: metodologie, potenzialità e criticità
No full textQuesto articolo vuole approfondire la tematica della fotomodellazione applicata all’architettura, in particolare ad edifici porticati, descrivendo ogni passaggio necessario per ottenere un modello tridimensionale texturizzato dal reale tramite un set fotografico.
Le potenzialità e le criticità di questo metodo sono messe in evidenza attraverso la presentazione di un caso di studio sviluppato nell’ambito di una ricerca coordinata dal Dipartimento di Architettura dell’Università di Bologna
Conformation of a Flexible Miura Pattern on a Double Curvature Surface
No full textThis paper proposes a design method, through a case study, to explore the conformation of any corrugation to a single or double curvature surface using Grasshopper with Kangaroo. The research focuses on the Miura-ori [8] which is one of the simplest 1 DOF rigid-foldable corrugation. It has limited spatial configurations, and at first can’t be conformed to a generic surface, but including the flexibility of the faces it can conforms to a wider range of surfaces. The flexibility of faces, has been simulated triangulating the quadrangular faces and applying a “stiffness” controller to the relative rotation freedom of the new triangular faces. This study is aimed at architects and designers who are not familiar with origami mathematics and physical formulations, and it want to carry out an easy approach with which it can be possible to make preliminary shapes-searching studies before the prototyping. For this reason, widespread pieces of software, used by architects and designers, have been chosen. In the conclusions, the pros and cons which can be encountered using this methodology are highlighted. Some precautions and checking methods are explained to avoid deceitful issues which can be encountered using these kinds of tools

Towards a Methodology for the Digitisation of Unbuilt Cities: from ‘Drawn’ Architecture to 3D Landscape
No full textThe paper illustrates the first step of a methodological workflow under development for the valorisation and communication of the documentary heritage. Archival drawings offer numerous insights into the past. Still, they often remain hidden from a broader audience in favour of specific and disciplinary studies that pertain to the history of architecture but also overlap with the science of representation. Digital technologies now allow the reconstruction or reinvention of a past that never existed, made up of ‘drawn’ architecture that, thanks to 3D modelling, can take shape and be narrated interactively and engagingly. Studies of this nature have often been undertaken by the discipline of Disegno, facing the complexity of virtual reconstruction at an architectural scale. This work illustrates a process that aims to systematise hypothetical virtual reconstruction within an urban context. This approach was made possible thanks to the Atlases of Mauro Guidi (1761-1829), an Italian architect from Cesena (Emilia Romagna) who, from the 18th century until his death, dedicated himself to the study of numerous architectural themes: public buildings, palaces, temples and churches. In particular, in Atlas 48, conserved at the Malatestiana Library of Cesena, project drawings can be consulted, accompanied by a textual description of two utopian projects for the cities of Cesena and Cesenatico: New Cesena and New Cesenatic

Dal foglio allo schermo: la modellazione tridimensionale dei disegni di Leonardo
No full textCompared to a two-dimensional photographic image, a digital three-dimensional model offers several advantages: it can describe the shape of a drawing and its media replicating its optical properties; it can efficiently document its state of conservation by highlighting the overlaps and changes occurred over time; and, finally, it can be displayed interactively from multiple points of view and under the correct lights showing even the finest details. In accordance with this working hypothesis, the drawings of Anatomia dei disegni [Reloaded] exhibition were reproduced three-dimensionally with the ambition of providing both visitors and scholars with a tool that recreates most of the features of the original drawings. The digital model thus narrates the drawing techniques and the complex contents that their author has transferred into them. Using the photometric stereo technique – a minimally invasive technology exploiting a limited number of photographic images captured with lights in the visible spectrum only – the models of the five drawings exposed were created with nLights, a software developed to generate the 3D shape and the bitmaps required to replicate the optical properties of the materials used by Leonardo da Vinci to trace his figures and texts
Perspective Studies on the Adoration of the Magi by Leonardo da Vinci
No full textThis paper aims to unravel the perspective construction used by Leonardo da Vinci for his iconic and celebrated unfinished painting the Adoration of the Magi. This study is the final step of years-long research brought forward by our department focused on the study of the perspective construction used by Leonardo in the preparatory drawings of his masterpiece. The first two published studies demonstrate how Leonardo re-interpreted the Albertian rules of perspective construction and used them in a non-rigorous way to draw the architectural elements of the preparatory drawings. Starting from these discoveries, this contribution aspires to complete the analysis by investigating if the same aberrations and formal errors are also present in the final painting. By inverse construction and comparison with the preparatory drawings, we observed probable perspective aberrations analogous to those observed in Uffizi’s preparatory drawing

Parametric Design of Applied Origami with a Synthetic Computational Approach
No full textIn this paper, we present a series of case studies of origami-like geometries modelled and animated following the principles of the synthetic method applied through parametric modelling applications. The aim of this research is to analyze the benefits and criticalities of the proposed method in the field of applied origami design. The presented method will be compared with the algebraic-based analytical approach highlighting the strengths and weaknesses of both methods. This paper is based on the PhD thesis of the last Author and we present a selection of the most interesting generative algorithms we have studied and designed
