AR METHODS FOR THE VISUALIZATION OF THE LOST MARBLE “TRIBUNA” IN THE MAIN APSE OF THE CATHEDRAL OF PALERMO
2022
Abstract. In recent years research works have shown that augmented reality tools can offer effective support for the dissemination of architectural heritage, when integrated into the information data extracted with surveying and representation tools and further data from other sources, e.g., history.The development and permanent updating of software platforms dedicated to augmented reality, i.e., Apple's ARKit and Google's ARCore, as well as the introduction of new features, offer today affordable support for the development of AR solutions.Some operational difficulties are due to the rapid and constant evolution of the technologies; the available solutions can be compared to prototypes and…
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.
Dallo scavo archeologico alla riprogettazione virtuale di un edificio: La chiesa a doppia abside del casale di Quattro Macine, Giuggianello (Lecce)
2003
The increasingly widespread use of computational technologies in the archaeological field it has opened up new possibilities of research thanks to the passage of information technology from simple support for "management and documentation" of data as a tool for the "production and analysis" of data themselves. Nowadays, having new software from computer-aided architectural design (Computer Aided Design) it is possible for the archaeologist to use the computer to realize a virtual reconstruction intended as a tool of archaeological analysis of an artifact building, retracing all the individual steps of the activity constructive up to the original architectural project. To proceed in this wor…
Ricerche a Solunto (2022)
2023
New Investigations at Solunto (2022) ∙ The last fieldwork campaign in Solunto by the University of Palermo, in the sanctuary above the theatre and in the baths near the agora (the North Baths), obtained some relevant results concerning both the building sequences and the architectural configurations. In the sanctuary, a clearer picture is emerging of the oldest layout, dating from the 4th century B.C. (1st phase). After the first reshaping of the street grid and of the urban layout (2nd phase), in the second half of 2nd century B.C., an overall restyling (3rd phase) gave the whole sanctuary area an impressive organization into terraces linked through ramps and stairways. A striking feature,…
