Techniques and procedures for the definition of AR applications in architectural and archaeological contexts
2022
The growth and development of Augmented reality applications and their use in different contexts has been recently fostered by two factors: i) the hardware and computing power of mobile devices has been radically improved; ii) Apple and Google have released two development platforms for AR applications. AR has been a major topic in research on cultural heritage fruition for many years, but the latest developments are really promising, and they seem capable of overcoming the difficulties that have delayed the diffusion of this technology. The paper focuses the potential and criticalities of augmented reality systems used for fruition purposes in architectural and archaeological contexts. The…
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…
The Nymphaeum of the Tritons at Hierapolis of Phrygia (Turkey) from excavations to 3D-virtual reconstruction: an example of integrated methods in the…
2011
The Nymphaeum of the Tritons at Hierapolis of Phrygia is a monumental fountain of the Roman period with an imposing marble façade. Within the activities of the Italian Archaeological Mission the Nymphaeum is currently being studied by a team from the University of Messina with the goal of understanding its original layout and its history. The starting point of the study is the wealth of data provided by stratigraphic excavation of the building, particularly by the extensive archaeological deposits formed by the blocks of the façade collapsed into the pool of the fountain following an earthquake in the 7th century AD. The need to process a large amount of data required the creation of a comp…
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…
Experiments on the Virtual City: Three-Dimensional Reconfigurations of Missing, Never Realized or Destroyed Urban Areas
2011
We present two works on the "Virtual City" held at Palermo. They are about the three-dimensional reconfiguration of urban places that show evidence of "invisible" architecture, this is because in one case there were ancient monuments now destroyed, or in another case projects designed for the urban void and never made. The aim is to involve new forms of communication for the development of cultural tourism.
Una chiesa scomparsa “dentro della nuova, assai più magnifica”. Progetti e ricostruzioni della cattedrale di Mdina tra Medioevo ed Età Moderna
2023
A corpus of drawings attributable to the seventeenth and eighteenth centuries, and preserved in the Diocesan archive of Mdina, allows us to better understand the reconstruction of the Cathedral of Malta after the earthquake of 1693, which damaged the medieval building. This had already been interested, a few years earlier, bu some works that had affected the presbytery area. The survey and project drawings, partly published but never studied in depth, offer valuable information on the medieval church and on the transformation process, on the relationship between the pre-existing buildings and the new projects. Starting from the available drawings, and with the support of documentary data an…
Il progetto di Archeologia Virtuale ad Alesa Arconidea
2023
The Virtual Archaeology project at Alesa Arconidea · Virtual Archeology is the field of application that finalizes the use of information technologies for the knowledge, enhancement and communication of the archaeological heritage. It deals with the reconstruction of artifacts, buildings, landscapes of the past through three-dimensional models, hypertexts and multimedia solutions. The goal of Virtual Archeology is to promote the development of formalized investigation procedures and methodologies to acquire, represent, process and communicate data while producing new information and research tools that go beyond traditional forms and bring a contribution to the progress of the studies and p…
Ricostruzione virtuale delle crociere dell'aula della chiesa di San Domenico a Cagliari (XVI sec.)
2016
Il saggio affronta la ricostruzione virtuale delle crociere dell’aula della chiesa di San Domenico a Cagliari, distrutta nel 1943 dai bombardamenti alleati che colpirono la città. La ricostruzione virtuale, combinando gli strumenti dell’indagine storica e della rappresentazione digitale, è stata impiegata per comprendere il processo costruttivo della copertura dell’aula. Lo studio ha inoltre permesso di elaborare una più corretta interpretazione dei dettagli linguistici e delle caratteristiche costruttive delle crociere, consentendo di elaborare nuove ipotesi sulla fabbrica, attraverso la comparazione con architetture coeve. This paper focuses on the 3D virtual reconstruction of the star-sh…
Rebuilding Palermo in the Middle Ages: A Virtual Approach
2020
A long sequence of demolitions, transformations, interpretative restorations eliminated or compromised a series of civil and religious buildings built between the XII and early XVI centuries in Palermo. For many of these architectures, graphic, photographic and documentary evidence exists and can be found. Within an extensive project of the Department of Architecture of the University of Palermo, based on the collaboration between different disciplines, we intend to offer an essay of the possible results that the synergy between historical research and representation can offer. Chosen case is a fifteenth-century civil building located in the San Francesco district, of which some fragments r…
La perduta Chiesa dell'Annunziata presso Porta san Giorgio a Palermo: ipotesi e ricostruzioni virtuali
2020
The Annunziata church was destroyed by the bombings of the Allies on May 9 1943 on the city of Palermo. However, important evidence remains of the church, built at the end of the 16th century and located near the San Giorgio gate: a 1832 drawing by Pierre-Joseph Garrez, preserved in Paris, at the École nationale supérieure des Beaux-Arts, the survey of the architect Nino Pollaci of the early twentieth century, a series of historical photos, the surviving architectural fragments such as the capitals and the painted wooden coffered ceiling, preserved in various Palermitan museums, and above all the bell tower, still the only trace on the site of the now disappeared church of the Annunziata.
