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.
Recensione di Vincenzo Cirillo: Feste Settecentesche a Napoli. Disegni e progetti per l’architettura effimera. Napoli: La Scuola di Pitagora, 2021
2022
The book by Vincenzo Cirillo focuses on the ephemeral Neapolitan architecture of the 18th century, it excels in the exploration and deepening of the Neapolitan experience by suggesting new approaches to the historical and cultural study of the city of Naples.
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 The graphic restitution of the survey provided new information and unpublished images of the castle.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…
La memoria fotografica dell’architettura : restituzioni prospettiche e ricostruzioni
2023
This book explores perspective restitution from photographs for the reconstruction of buildings and urban sites that no longer exist or have suffered many alterations over time. Digital drawing and modelling tools overcome many of the limitations that, in the past, made perspective restitution from photographs inaccurate and inconvenient. Traditional drawing tools made perspective restitution from photographs difficult, especially when vanishing points appeared at a great distance from the image frame. The results of perspective restitution were either 1D or 2D objects, i.e. points, segments, angles, planar figures and profiles, that were revolved into the picture plane. By contrast, digita…
From aerial survey to representation and visualization: the Temple G of Selinunte
2022
The paper reports the outputs of a research work focused on the segmentation of meshes generated from aerial photogrammetric survey, aiming at the implementation of a database integrated in a web-based Information System developed with 3D-Hop technology, that uses models as the access point to information data. Segmentation is a relevant topic in cultural heritage documentation, since it is the a pre-requisite for the development of systems that connect information data to 3D models. The chosen case study is the Doric Temple G of Selinunte, an archaeological site in southern Sicily. Temple G, one of the biggest Doric Temples of Magna Graecia, it is today a huge heap of ruins, probably due t…
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…
Il restauro virtuale dei sistemi decorativi e studio ricostruttivo dell’insula
2018
Il presente contributo rientra nell’ambito di in una più vasta linea di ricerca denominata “Progetto Hierapolis Virtuale”, sviluppata a partire dal 2007 e finalizzata alla ricostruzione tridimensionale degli edifici della città. A differenza di altre ricerche condotte sui monumenti di Hierapolis, l’attuale studio riguarda solamente una singola fase edilizia dell’insula, relativa alla grande stagione monumentale di età protobizantina riferibile a un periodo posto tra il VI e la prima metà del VII secolo. Tale scelta è stata dettata unicamente dalla quantità e dalla qualità dei dati archeologici utili ad uno studio ricostruttivo il più possibile scientifico per contribuire ad una maggiore con…
Il contributo delle tecnologie digitali per la valorizzazione del patrimonio rupestre pugliese
2016
The essay concerns the recent work carried out as part of a multidisciplinary research on some rocky churches in the southern Apulia, conducted in collaboration with the Chair of History of Medieval Art of the University of Salento and of the University of Bari. The work aims at the knowledge and the monitoring of the fresco paintings inside three rocky environments, two of which are located in Lama d’Antico, in Fasano (BR), and the other two in Vaste di Poggiardo and Giurdignano (LE). The contribution illustrates methods and data acquired during the fieldwork, carried out through a multidisciplinary approach. From the image-based Techniques for the survey in Camera-Scanner to the restituti…

Negative image-based (NIB) screening is a rigid molecular docking methodology that can also be employed in docking rescoring. During the NIB screening, a negative image is generated based on the target protein’s ligand-binding cavity by inverting its shape and electrostatics. The resulting NIB model is a drug-like entity or pseudo-ligand that is compared directly against ligand 3D conformers, as is done with a template compound in the ligand-based screening. This cavity-based rigid docking has been demonstrated to work with genuine drug targets in both benchmark testing and drug candidate/lead discovery. Firstly, the study explores in-depth the applicability of different ligand 3D conformer…
A Molecular Dynamics-Shared Pharmacophore Approach to Boost Early-Enrichment Virtual Screening: A Case Study on Peroxisome Proliferator-Activated Rec…
2016
Molecular dynamics (MD) simulations can be used, prior to virtual screening, to add flexibility to proteins and study them in a dynamic way. Furthermore, the use of multiple crystal structures of the same protein containing different co-crystallized ligands can help elucidate the role of the ligand on a protein's active conformation, and then explore the most common interactions between small molecules and the receptor. In this work, we evaluated the contribution of the combined use of MD on crystal structures containing the same protein but different ligands to examine the crucial ligand-protein interactions within the complexes. The study was carried out on peroxisome proliferator-activat…
