Lettura stratigrafica degli elevati e restituzione 3d della Chiesa
2009
Il contributo riguarda lo studio architettonico della chiesa attraverso un percorso metodologico che parte del rilievo architettonico e dalla lettura stratigrafica degli elevati fino all'ipotesi di ricostruzione virtuale dell'edificio The contribution concerns the architectural study of the church through a methodological path that is part of the architectural survey and from the stratigraphic reading of the elevated to the hypothesis of virtual reconstruction of the building
Riannodare il passato e il presente con la restituzione prospettica: ricostruzione della perduta chiesa delle Stimmate di Palermo da foto d’archivio
2020
La restituzione prospettica appartiene di diritto al corpus disciplinare della geometria descrittiva, come problema inverso della prospettiva. In passato tale tecnica è stata utilizzata ben poche volte per la ricostruzione da immagini fotografiche di architetture e opere d’arte perdute; gli strumenti digitali per la rappresentazione offrono però l’opportunità di recuperare la restituzione prospettica come strumento efficace per la ricostruzione di monumenti perduti ritratti in foto d’epoca. Il caso studio prescelto è la chiesa delle Stimmate di Palermo, demolita alla fine del XIX secolo per la costruzione del Teatro Massimo. La chiesa ad aula era delimitata da pareti con nicchie arcuate poc…
La ricostruzione da immagini con tecniche di restituzione prospettica
2018
Il contributo è incentrato sulla ricostruzione di opere di architettura perdute da fotografie attraverso l’uso di tecniche di restituzione prospettica. Una breve introduzione illustra le ragioni che relegano la restituzione prospettica a un ruolo secondario nel contesto delle ricostruzioni virtuali; il paragrafo successivo illustra i risultati di un test sul confronto fra restituzione prospettica da singolo fotogramma e restituzione SfM. Il paragrafo conclusivo descrive la ricostruzione virtuale di una chiesa di Palermo, demolita nella prima metà del XX secolo e documentata da poche foto d’epoca. The paper focuses the 3D reconstruction of buildings that were destroyed during the World War I…
PERSPECTIVE RESTITUTION FROM VIEW CAMERAS PHOTOS
2022
Abstract. The paper aims at discussing the accuracy of perspective restitution from view camera photos; view cameras are non-standard cameras frequently used in the past century for on field shooting of buildings and urban sites; this is why the reconstruction of lost buildings often deals with photos taken with a view camera. The case study chosen for the proposed experiment is an urban complex built in Palermo in the ‘50s. The site features a very regular layout with surfaces at right angle, that supports the graphic reconstruction of photos’ inner and outer orientation. The site has been surveyed with a laser scanner; the point cloud provided the metric information needed for the evaluat…
From the “Sacred Theatres” of Andrea Pozzo to the International Truncated Calotte: History and Representation of the Immacolatella Church’s Tribune i…
2022
The contribution, divided between history and representation, aims to analyse the design genesis and the sources used by the architect Giovanni Amico for the modernization of the Immacolatella church’s tribune in Trapani (since 1732). The church is devoid of studies and surveys with digital instrumentation but its unique compositional characteristics, which exploit the theme of the manipulation of space and light for scenographic and liturgical purposes, require in-depth analysis. The solution applied to the church tribune combines different compositional themes linked to the Roman design world and in particular by Andrea Pozzo in relation to the “sacred theatres” produced for the Jesuits a…
INTEGRATED SURVEYING AND MODELING TECHNIQUES FOR THE DOCUMENTATION AND VISUALIZATION OF THREE ANCIENT HOUSES IN THE MEDITERRANEAN AREA
2015
The paper is focused on the layout and testing of a workflow for the documentation of archeological remains, addressed to the study, visualization and information data input. Topographic, laser scanning and photogrammetric data have been used to build up 3D textured models of three ancient houses built in Sicily and in Tunisia in the Hellenistic and Roman age. 3D models have been used to extract conventional representations (plans and sections), analyze the geometric and proportional features and propose a virtual reconstruction of the original layout. The final step of the research work has been addressed to the creation of a web-based tools for the visualization of the models addressed to…
Lettura stratigrafica delle murature e studio architettonico della Chiesa
2018
The contribution concerns the study of the construction phases of the church of Santa Marina in Muro Leccese (LE) realized through the stratigraphic reading of the masonry that has allowed, later, to be able to carry out the reconstructive study of the building through a digital model.
Nuove ricerche a Solunto (2021)
2021
New researches in Solunto (2021) · The paper presents an overview of the ongoing researches in Solunto by the University of Palermo. In 2021 stratigraphical sondages were undertaken in two areas of the town: 1) in the great sanctuary above the theatre, in the frame of a major project aimed at addressing several still unresolved issues. That area, as a matter of fact, has never been considered as a whole; the sacred buildings have not been studied, and their mutual relationships and the links with the adjacent terraces have never been properly examined; 2) in the North Baths near the agora, as a corollary of the systematic study of water management, some sondages were made by G. Polizzi. Fin…
La cornice Ionica del tempio G di Selinunte. Rilievo e interpretazione per la ricostruzione virtuale.
2013
This research is focused on the virtual reconstruction of the Ionic cornice of temple G of Selinunte, as a case study for the definition of a virtual reconstruction method of collapsed walls elements in archaeological contexts. The complexity of the ruins of the temple suggested a thorough archaeological analysis of the fragments of the Ionic cornice that made it possible to identify traces of the construction process left by stonecutters during the worksite such as unfinished surfaces. The study of these surfaces, together with the dimensional data surveyed, provided the information to reposition the fragments in their supposed original position, and thus develop a virtual reconstruction o…
Hulot's Selinunte: digital analysis and virtual reconstruction
2021
Some drawings feature a powerful evocative nature, capable of presenting a truthful vision that can replace, in collective imagination, the actual expression of reality. This is the case of the "restorations" of Selinunte proposed by the French architect Jean-Louis Hulot (Paris 1871 -1959) which still today evoke the splendours of the ancient city. Thanks to his accurate surveys and inspired by the visit to the remains of further ancient cities such as Priene, Tera, Delos, and Pompeii, Hulot proposed in his watercolour drawings a vision of a "living" city, rendered at the height of its architectural and social magnificence. The paper presents a study on digital solutions that combine data f…
