Castellaccio of Monreale: From the Survey to the Visualisation of Virtual Reconstructions
2023
On Monte Caputo near Monreale stands a castle, presumably built in the twelfth century. The paper presents the first results of a still in progress survey activity, carried out on the entire monument using laser scanning and photogram-metric methods. This activity was carried out as part of a scientific agreement stipu-lated between the University of Palermo, Department of Architecture and the Club Alpino Siciliano, owner of the Castle. The graphic restitution of the survey provided new information and unpublished images of the castle. It was then possible to formu-late hypotheses on the virtual reconstruction of lost configurations. This was achiev-able thanks to the survey analytical read…
La memoria fotografica dell’architettura : restituzioni prospettiche e ricostruzioni
2023
This book explores perspective restitution from photographs for the reconstruction of buildings and urban sites that no longer exist or have suffered many alterations over time. Digital drawing and modelling tools overcome many of the limitations that, in the past, made perspective restitution from photographs inaccurate and inconvenient. Traditional drawing tools made perspective restitution from photographs difficult, especially when vanishing points appeared at a great distance from the image frame. The results of perspective restitution were either 1D or 2D objects, i.e. points, segments, angles, planar figures and profiles, that were revolved into the picture plane. By contrast, digita…
From aerial survey to representation and visualization: the Temple G of Selinunte
2022
The paper reports the outputs of a research work focused on the segmentation of meshes generated from aerial photogrammetric survey, aiming at the implementation of a database integrated in a web-based Information System developed with 3D-Hop technology, that uses models as the access point to information data. Segmentation is a relevant topic in cultural heritage documentation, since it is the a pre-requisite for the development of systems that connect information data to 3D models. The chosen case study is the Doric Temple G of Selinunte, an archaeological site in southern Sicily. Temple G, one of the biggest Doric Temples of Magna Graecia, it is today a huge heap of ruins, probably due t…
A virtual reconfiguration of two destroyed neighborhoods in the Old Town of Palermo
2018
The proposed contribution deals with the topic of virtual three-dimensional reconstructions on an urban scale. The choice was oriented on significant samples of city portions that over the centuries have undergone substantial transformations or distortions: the aim is to reconstruct their history backwards, starting from the current survey and using the tools of virtual representation to reconfigure the forms of the past and tell their events. From here comes the idea to create, for pieces, a hypertextual study of the urban image of Palermo: the theme of the transformation of the city, of change and of complexity, opens up differentiated research paths. The hypertext choice was almost obvio…
Visual Culture and Cultural Heritage: ViC-CH a Synthesis Between Digital Representation and Heritage Experience
2019
The dissemination possibilities offered by digital technologies provide multiple ways of reading and fruition of the cultural heritage. In order to define a visualization and communication strategy through images, the paper shows some of the results of the ViC-CH Visual Culture and Cultural Heritage workshop, which involved the University of Trento and the Free University of Bozen-Bolzano. The graphic elaborations focused on the Library of the Priest Seminar in Brixen; photomodelling, short films with drone shots and virtual visits have been some of the ways of manipulating the image for the animation and realistic visualization of a cultural heritage not easily accessible to date (The pape…
Disegnare il non costruito: la Caserma-Teatro G.I.L. di Luigi Moretti a Piacenza
2021
Come si misura la distanza che intercorre tra noi e un edificio rimasto sulla carta? Questa domanda apparentemente pretestuosa può esserci utile per incardinare delle riflessioni sull’uso del Disegno nello studio dell’architettura non realizzata, soprattutto quella del primo ‘900. Non a caso, nell’approfondire un progetto rimasto tale di Luigi Moretti per la città di Piacenza (la locale “Caserma-Teatro G.I.L.”) si è voluto prioritariamente verificare un metodo che prevede l’applicazione di alcuni degli strumenti propri della Scienza della Rappresentazione. I culmini di questo processo lento di decodifica e successiva esegesi sono stati certamente l’analisi grafica (che ha permesso di discre…
Introduzione a culture visibili
2017
Culture visibili, ovvero spazi fisici e virtuali generati dalla stratificazione di storie, dall’accumulazione di significazioni e progetti, che diventano luoghi ideali in cui leggere e interpretare, in un continuo sistema dialettico, la memoria, le narrazioni, i percorsi, gli scenari futuri dei territori, di coloro che li abitano e del loro modo di comunicare. Se le città invisibili erano luoghi immaginari ed evocativi, metafore della realtà, le città visibili e con esse le loro culture, sempre più a rischio di divenire invisibili, sono luoghi tangibili, concreti, spesso territori fragili e permeabili dove la comunicazione svolge un ruolo determinante. Visible cultures, meaning physical and…
Proportions in Salvatore Caronia Roberti Between Theory and Practice
2022
AbstractIn 1949 Salvatore Caronia Roberti published the volume Introduzione allo studio della composizione architettonica. It is a compendium of his own studies and research came together in his architecture, testifying to the close interweaving of theory and practice. Caronia Roberti was a student of Ernesto Basile, one of the leading exponents of Art Nouveau, a style in which proportions played a marginal place. He later broke away from the Master’s school to attempt a new path in which geometry and proportion constitute the core of his theoretical research. This study aims to highlights the organic nature of Caronia Roberti’s thought, between architectural history and representation, by …
Masonry Sail Vaults in Maltese Architecture: Geometrical Analysis for the Study of Building Processes
2023
This research concerns the introduction and dissemination of masonry sail vaults in Malta between the sixteenth and the eighteenth centuries. A digital survey is produced to capture a reality-based 3D model, undertake analysis, and compare case studies with the aim of interpreting the sail vaults' construction systems.
Visual Perception and Graphic Analysis. The Pattern of Inlays in the Cathedral of Palermo
2017
The Cathedral of Palermo is one of the monuments belonging to the Arab-Norman Itinerary, declared a UNESCO World Heritage site in 2015. This text uses geometric analysis to describe some of the inlaid circular designs from the eastern façade, the corner towers and the apses. The cataloguing of the two-tone geometric motifs also reveals aspects that can be linked back to the laws of visual perception. Hence, the text investigates these aspects based on a new reading. In fact, decomposing these elements based on the experience of their perception also facilitates the recognition of elementary figures. The attempt made in this brief text intends to induce a new perceptive awareness resulting f…
