This paper presents some results of research aimed at defining a parametric tool for modelling complex decorative apparatuses of domes based on geometric rules definition and building techniques. MaTiDo, Majolica Tiles on Domes, is an adaptive tool that allows a user to place “fish scale” on revolution domes and oval or elliptical ones, on domes with ribs and domes without ribs. MaTiDo can be used to reproduce the look of the real domes and virtually reconstruct domes modified or destroyed. These ideal models are suitable for different uses, for Cultural Heritage dissemination or in HBIM process. The main geometric problem to address is how to evenly distribute on doubly curvature surfaces flat tiles that are all the same size. MaTiDo is being developed for colour automatic distribution on tiles in order to generate different decorative patterns on extrados dome surfaces.

Reality-based tools for architectural surveys allow the acquisition of multiple integrated data (morphological, material, colorimetric). The number and heterogeneity of the acquired data represent an advantage for information gathering; yet, at the same time, this calls for new considerations regarding big data management and output. Following these premises, this article presents the first results of an ongoing research activity aimed to the definition and testing of parametric tools (VPL for interoperability – BIM/H-BIM) for RGB-based, semi-automated thematic representations of the conservation state of architectural façades. Specifically, the contribution proposes an algorithmic generative definition for decay phenomena mapping. This was experimented on the façades of the Church of the Archconfraternity of Santa Maria delle Grazie e Sant’Andrea Apostolo (Naples, Italy), surveyed through digital terrestrial photogrammetry and thermographic cameras. Orthophotos and thermographic mosaics constitute the types of RGB mapping used to validate the designed tool. This process is aimed to the visualization/modeling of data related to complex phenomena and to the rapid production of graphs for documentary and preventive purposes.

This research work into Evolutionary Computing field aims at improving a dataset of algorithmic gen-erative definitions able to return an optimized ‘semi–ideal’ curve that best fits a generic reality–based profile, starting from some of its points. This paper shows GAs_Genetic Algorithms applications especially with regards to study, interpretation and definition of generic polycentric curves. Current VPL tools (Galapagos–Rhino, McNeel) allow to test Evolutionary Theories for problem solving and decision makingin architectural research field. According to a human driven approach, an operator defines GENOME, FUNCTION and FITNESS to drive the Evolutionary Solver towards optimized solutions. Some case studies from Historical/Existent Architectural Heritage are used to show how GAs can simplify the digitalization process and big data interpretation.

This chapter shows some results of academic research and didactic activities about innovative design and productive processes based on modeling and digital fabrication integrated strategies. The results of these experiments are customizable lamps prototypes. Digital modeling is based on algorithmic-generative visual scripting approach and geometric theories to manage primitive or complex shapes and patterns to optimize digital manufacturing. The following paragraphs and sub-paragraphs describe a prototypes collection designed, manufactured, and assembled by students on their first experience in VPL and digital prototyping. Lamp prototypes are made using additive and subtractive techniques according to different shaping approaches. The main goal of this academic approach is to collaborate in design and architectural geometry research field: the main goal is to support training and entrepreneurial activities of students aimed at management of complex data systems according to new potential of digital tools for advanced shaping, new manufacturing processes, and ecological strategies.

L’utilizzo delle tecnologie digitali per la documentazione e la valorizzazione dei Beni Culturali ha avuto un forte impulso nell’ultimo decennio soprattutto per l’ampia diffusione di strumenti per la modella- zione e la realizzazione di immagini immersive e dei dispositivi che consentono la fruizione interattiva a distanza attraverso l’utilizzo della rete. Sempre più numerose sono le sperimentazioni di sistemi integrati multimediali di realtà virtuale, applicazioni immersive, realtà aumentata, Serious Games, etc. che hanno come obiettivo la digitalizzazione eo la ricostruzione virtuale, di manufatti e contesti, e la definizione di strategie in grado di coinvolgere gli utenti stimolando comportamenti attivi. Il contributo si colloca in questo ambito e mostra gli avanzamenti di una ricerca in progress finalizzata allo sviluppo di artefatti cognitivi interattivi web-based, fruibili in situ e/o in remoto, con l’obiettivo di trasferire contenuti culturali e stimolare la fruizione partecipata del patrimonio utilizzando modalità ‘pseudo-ludiche’ (gamification). A scopo esemplificativo, si riportano alcune applicazioni realizzate per la Torre del Partito Nazionale Fascista di Luigi Cosenza (progetto mai realizzato) e per l’Arena Flegrea di Giulio De Luca (edificio demolito e ricostruito), che hanno consentito di affrontare tematiche relative alle diverse possibili esigenze comunicative, di valutare le potenzialità degli strumenti e di sperimentarne la flessibilità.

The contribution is part of an interdisciplinary research that aims to address the problems of knowledge, interpretation and documentation of vulnerable structures such as the brick Renaissance domes in Campania (XV-XVI century). The goal is to analyze the relationship between Survey, Historic Building Information Modelling (HBIM) and 3D parametric models based on geometric rules from Treaties to study and to manage Cultural Heritage. HBIM is generally based on scan-to-BIM process that allows to generate 3D model from point cloud. The reverse modeling process, from a point cloud to parametric geometric model, poses a series of issues at the center of cultural debate that currently takes place around HBIM. The experimentation underway is part of this research field with the aim of using the parametric approach as a tool able to introduce an additional methodology for big data interpretation. Currently we can identify two different approaches for the construction of a HBIM system: building a simplified model by identifying the shape grammar or building the geometric components from survey without using pre-compiled objects libraries, following the scan to BIM logic. In our research we are going to identify an "hybrid" methodology. Generally the process is based on the knowledge and critical abilities of individual scholars, the idea is to increase the efficiency of the system through collaborative workflow forms that allow to optimize the processes through effective knowledge management actions. We are going to use procedural modeling techniques to generate HBIM domes library.

This paper aims to explore shadow in Street Art by collecting and testing shadow street artworks as main tools to investigate interaction between man, urban environment and social identy as psychogeographic manifestation. Psychogeography, introduced by Debord in the 1950s, studies correlations be-tween psyche and environment, challenging classical geography and supporting the creative re-definition of urban space. According to these premises, Shadow Street Art can be considered as an alternative form of Street Art thanks to the strong psycho-environmental dimension and involvement generated by exclusively monochrome, colorless graffiti and sudden, evanescent projections. Furthermore, the main goal of street artists who work with real shadows is to design 4D works: time is the main parameter to control the whole process. Parametric-generative digital tools allow to simulate dynamic projective process and perspective anamorphic transformation of shadows on walls, streets or squares according to specific environmental (geographical, temporal parameters) and technical (light design) parameters. From projection to invention, the aim of this contribution is to decline Shadow Street Art trough artifacts in which shadow is both an artistic expression, a narrative tool and a research object, providing references to inspire new creative works for non-invasive enhancement of urban places and buildings.DOI: https://doi.org/10.20365/disegnarecon.24.2020.14

I siti ex-estrattivi rappresentano una delle maggiori sfide per le politiche di rigenerazione territoriale in Europa e nel mondo, definiti spesso, nelle loro connotazioni spazio-tipologiche, con accezioni che ne lasciano generalmente intendere qualità negative non evidenziando il loro valore di paesaggi culturali. Nonostante un preliminare e non esaustivo contesto normativo di riferimento nazionale e regionale, il tema della valorizzazione di tali ambiti necessita di maggiore attenzione da parte della comunità scientifica, soprattutto nel rispetto dell’attuale scenario internazionale (Direttiva Europea 85/337). Nello specifico, per la sua numerosa concentrazione di aree estrattive, peculiare attenzione merita la realtà territoriale della regione Campania, con la messa a punto di un sistema informativo aperto da cui desumere una rappresentazione sinottica dello stato di fatto che integri l’identità storico-culturale con la dimensione figurativa e percettiva dei luoghi.

Geometric understanding allows us to solve many problems in manufacturing complex surfaces and geometric rules can lead the project from theory to practice (Pottmann in Architectural geometry. Kindle edn, 2015). Digital fabrication technologies are evolving and becoming more and more widespread. Knowledge of fabrication methods available and parametric design tools, based on geometry, are changing the designer way to think. Advances in this field promote experimental use of new materials but also innovative use of traditional materials, such as wood. Our research in the field of non-developable surfaces fabrication move from “paneling” to “kerfing”, or “kerf bending”. This subtractive manufacturing technique consists in transforming a rigid material in a flexible one and the problem to solve is how to cut the flat shape to obtain the 3D design surface. This is a quite simple question to solve for a developable surface, but it is a very complex problems for a double curvature surface manufacturing. The aims of our research are: analyzing the relationship between the curvature of surfaces and kerfing techniques; testing different ways to optimize the design of cutting patterns to bend a rigid materials; testing different ways to manufacture 3D surface from 2D panel. We are manufacturing some prototypes that are made up of pieces of developable helicoid and hyperbolic paraboloid.

Contemporary architecture is considered a dynamic system, capable of adapting to different needs, from environmental to functional ones. The term 'Adaptable Architecture' describes an architecture from which specific components can be changed in relation to external stimuli. This change could be executed by the building system itself, transformed manually or it could be any other ability to be transformed by external forces (Leliveld et al.2017). Adaptability concept is therefore linked to motion and to recent advances in kinetic architecture. In our research we are studying the rules that we can use to design a kinetic architecture using origami. Parametric design allows us to digitally simulate the movement of origami structures, we are testing algorithmic modeling to generate doubly curvature surfaces starting from a designed surface and not from the process. Our main goal is to study the relationship between geometry, motion and shape. We are interested, in particular, in complex surface manufacture using origami technique to design a kinetic and reactive ceiling.
