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…
Palazzo Lanza dei Principi di Deliella. Dai disegni di archivio di Ernesto Basile alla ricostruzione virtuale
2022
Il contributo indaga il progetto di Ernesto Basile, mai realizzato, per Palazzo Lanza dei principi di Deliella a Palermo, attraverso lo studio dei disegni originali (1895-1897). Questi consistono in 15 documenti grafici che raccolgono 5 piante, 6 prospetti e 4 viste prospettiche, che rappresentano quattro versioni di progetto con diverse soluzioni, di ognuna delle quali è possibile reperire una documentazione frammentaria e incompleta, riconducibile a tempi ideativi differenti. Il contributo ripercorre, mediante il ridisegno, il percorso compiuto da Basile per giungere dalla prima all’ultima versione, raccontando graficamente l’evoluzione della pianta dell’edificio che, dall’impianto simmet…
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,…
Toward a virtual reconstruction of an antique three-dimensional marble puzzle
2017
International audience; Abstract | Introduction | Related Work | Acquisition Setup, Proposed Prototype: Calibration and Visibility | Preprocessing of Scanned Three-Dimensional Fragment Data | Processing of Scanned Three-Dimensional Surface Data: Matching | Conclusion and Future Works | Appendices | Acknowledgments | ReferencesAbstract. The reconstruction of broken objects is an important field of research for many applications, such as art restoration, surgery, forensics, and solving puzzles. In archaeology, the reconstruction of broken artifacts is a very time-consuming task due to the handling of fractured objects, which are generally fragile. However, it can now be supported by three-dim…

Ricostruzione virtuale dei resti archeologici: sperimentazione di approcci integrati innovativi per lo studio e la valorizzazione dell’area sacra del…
2022
Il progetto di cui si presentano i risultati è rivolto all’ambito delle Scienze applicate al Patrimonio culturale e, nella fattispecie, all’applicazione di metodologie e tecnologie innovative di ricostruzione virtuale di supporto allo studio, alla valorizzazione e alla fruizione innovativa dei beni archeologici. Esso ha richiesto, per l’acquisizione delle competenze necessarie alla sua conduzione, lo svolgimento di uno stage presso la Virtutim srl in Roma, per la formazione all’uso delle tecniche di rilievo 3D e dei software di grafica e modellazione virtuale con cui sono stati realizzati i contenuti multimediali presentati di seguito, nonché un periodo di studio all’estero, presso l’Instit…
Dalla Fotografia alla ricostruzione: Porta Maqueda a Palermo
2022
The reconstruction of gone, or never built buildings has ever been one of the preferred subjects of digital representation. Many researches have focused the reconstruction of buildings that were modified by human actions, as wars or demolitions, or by natural causes as earthquakes or decay. Many buildings, destroyed or reshaped from the second half of the 19th century have been photographed before they vanished; when no drawing or document are available, the memory of the architecture layout of these buildings is entrusted to few period photos. Digital representation makes the reconstruction of gone buildings from period photos possible. Descriptive Geometry provides the conceptual and oper…
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…
The Virtual Reconstruction of the Aesculapius and Hygeia Statues from the Sanctuary of Isis in Lilybaeum: Methods and Tools for Ancient Sculptures’ E…
2022
Thanks to recent technological developments in 3D surveys, computer graphics and virtual reality, new scenarios have been opened for the documentation and enhancement of ancient sculptures. When not totally preserved, sculptures can be digitally reproduced, modified and visualized to simulate their physical or virtual reconstruction in a non-invasive way for specialists or for dissemination aims. The virtual sculptural reconstruction process starts usually from the 3D survey of real fragments, and then continues by integrating missing parts with 3D modelling techniques by means of source evaluation. Along with primary data sources (reality-based model), secondary data sources (photos, drawi…
Per un teatro dell'architettura e della città: teorie e pratiche di realtà aumentata alla Cité de l'architecture et du patrimoine al Palais de Chaill…
2017
Lo studio presenta gli esiti di una ricerca volta allo sviluppo di un allestimento museale con sole tecniche di realtà aumentata per la Cité de l’architecture et du patrimoine (Palais de Chaillot, Parigi). Realizzato sfruttando la recentissima piattaforma Google Tango, questo sistema permette al visitatore di accedere a contenuti multimediali e visualizzare ricostruzioni digitali 3D, appositamente elaborate, semplicemente inquadrando con uno smartphone Tango-enabled i calchi e i plastici esposti nel museo. This study presents the results of a research which aims to develop a museum exhibition planning, with interactive augmented reality techniques, at the Cité de l’architecture et du patrim…
