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…
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…
Maison Particulière. Graphic Reading and Virtual Reconstruction
2021
De Stijl, a modern and avant-garde movement of the early twentieth century, is considered the link between the pre-1914 avant-garde and the post-1918 International Style. The name derives from the magazine founded in 1917 and used for the promotion of the ideals ofNeoplasticism, theorised by Theo VanDoesburg. In 1924 Van Doesburg published the essay Tot een beeldende architectuur in which he explained a 16 points manifesto on the neoplastic vision of modern architecture. The analysis of the drawings and contra-constructions and the comparative reading of all the original drawings allowed for a series of graphic interpretations, which made the project understandable. This interpretative-reco…
I Telamoni del Tempio di Zeus ad Agrigento: rilievi, disegni e ricostruzioni
2013
Oggetto dello studio qui presentato è la ricostruzione di un intercolumnio del fronte esterno del Tempio di Zeus ad Agrigento, basata sul rilievo del Telamone oggi custodito presso il Museo Archeologico, sugli studi e i numerosi saggi di ricostruzione proposti dagli studiosi dal XVIII secolo fino alla metà dello scorso secolo e sulla analisi strutturale del Telamone ricostruito nel Museo. The drawings of the telamones, the giant statues placed the front of the Temple of Zeus in the archaeological area of Agrigento, have fascinated some of the most famous neoclassical architects in Europe. The virtual reconstruction of one intercolumnial of the Temple, based both on the range-based survey of…
Il Caffè Arabo alla IV Esposizione Nazionale di Palermo: dai disegni di Ernesto Basile alla ricostruzione virtuale
2016
A partire dalla rilettura di disegni originali di progetto e riproduzioni grafiche d’epoca, il contributo indaga il caffè arabo progettato da Ernesto Basile per la IV Esposizione Nazionale di Palermo. Il presente studio rientra nel filone delle ricostruzioni virtuali di architetture non più esistenti o solo disegnate e si configura quale tassello mancante di un lavoro più ampio e già edito riguardante la maggior parte del complesso espositivo. La ricostruzione virtuale si connota quale strumento di indagine e visualizzazione di un’architettura effimera, in una parte di città perduta. This text studies the project for the Caffé Arabo designed by Ernesto Basile for the IV Esposizione Nazional…
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…
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. T…
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.
