Levantamiento del templo G. parque arqueologico de Selinunte, Trapani. Sicilia. Informe general
2006
El trabajo de campo al que se refiere la presente comunicación, se puede considerar como la fase inicial del proyecto de levantamiento del templo G de Selinunte, ya que si bien se han podido tomar muchos datos del mismo durante la campaña de verano del 2005, quedan algunas zonas donde no ha sido posible acceder, por lo que será preciso completar la información conforme se vaya avanzando en el modelo. La dificultad mayor vendrá con la definición del propio modelo 3D, labor de investigación avanzada ya que actualmente no existen técnicas ni metodologías de referencia a nivel mundial en el uso de escaners láser 3d aplicados al campo de la arquitectura. Esta segunda tarea la estamos llevando a …
The Cathedral of Palermo : from survey to historic interpretation
2013
The Cathedral of Palermo was built by the Norman Kings, in the place where a mosque had been erected by the muslim governors of Sicily. The church has many features recalling the norman churches in northern France and in England, whilst some others are due to the contamination of norman, muslim and byzantine culture, that is peculiar of the so-called “arab-norman” architecture of medieval Sicily. In the XVIth century the Cathedral has been enriched by additions that did not affect its medieval features: a portico and a sacristy on the southern front, a sculptural decoration in the main apse. It was at the end of the XVIIIth century that the church underwent huge and extensive transformation…
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…
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…
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…
