A Quick Method for the Texture Mapping of Meshes Acquired by Laser Scanner

The methodology described in this article was developed in connection with two different projects and entails texture mapping by time-of-flight laser scanner. In order to verify its operational effectiveness and applicability to other contexts, sites with extremely different morphological characteristics were studied. The basic rationale of this simple method derives from the need to obtain different types of mapping – including RGB real colour images, infra-red images, false colour images from georadar scans, etc. – from the same scanned surface. To resolve this problem, we felt that the most appropriate step was to obtain a UVW mapping based on the high resolution real colour images and then use the samecoordinates to rapidly map the false colour images as well. Thus we fitted a device to the camera to determine its trajectory (similar to a gunsight); when scanned by the laser scanner in the same context as the monument, it makes it possible to know the exact coordinates of the viewpoint

VIDEOS AUTOEXPLICATIVOS PARA EL MUSEO EGIPCIO DE TURÍN

[EN] In the present project for the setting of the new Museo Egizio of Turin the “cultural message” has been charged to make a few specific 3D computer graphic (CG) movies, and aims to introduce the topics dealt with the rooms dedicated to queen Nefertari, the chapel of the painter Maia and the tomb of Kha, respectively. In these movies, the passivity of viewing is counteracted with an emotional approach that involves the visitor within an informative path where, despite of the inactive kind of interaction, the viewer is somehow involved in the events because he or she is emotionally invested in them. Thanks to this passive and “self-explaining” approach, the visitor will be enabled to understand the relations between different objects, some of which are not directly visible. Moreover, the visitor will be able to virtually insert the tombs within their original context and above all will have the possibility to visit them as they appeared at the moment of their discovery. This has been made possible thanks the use of integrated technologies of representation, able to enhance the virtualization process to a verisimilar level allowing a hyper-realistic and “participative” vision. The high level of realism of the virtual reconstruction, the visual effects and the cinematographic representation, with added emotions to the scientific contents, positively contribute to the “dreamlike displacement” of the visitor between the real and the virtual dimensions.[ES] En este proyecto para la construcción del nuevo Museo Egipcio de Turín el mensaje cultural fue dado a tres películas específicas en gráficos 3D, destinados a la introducción de los temas tratados en las salas dedicadas a la reina Nefertari, la capilla del pintor Maia y la tumba de Kha. En estas películas, la pasividad de la visión se ve compensado por un enfoque emocional que implica el visitante en un trayecto de información en el que, a pesar de la falta de actividad de disfrute, él es en realidad participante, porque emocionalmente involucrado. Gracias a este método, pasivo y “autoexplicativa” el visitante puede comprender las relaciones entre diferentes objetos, algunos no directamente visibles, como la momia de Kha y su esposa Merit, a ser posible reconstruir las tumbas en su contexto original, pero sobre todo la posibilidad de visitar, gracias a las técnicas de la arqueología virtuales, tales contextos como aparecieron en el momento de su descubrimiento. Todo esto es posible gracias a la utilización de tecnologías integradas para el estudio y la representación, capaz de llevar el proceso de virtualización a un grado de verosimilitud hiperrealista y “participativa”. El alto grado de realismo de las reconstrucciones virtuales, efectos visuales y técnicas de representación cinematográfica, añadiendo emoción al contenido científico, contribuyen positivamente a la “pérdida” del visitante entre el real y el tamaño dimensión virtual.Gabellone, F.; Ferrari, I.; Giuri, F.; Chiffi, M.

Digital Twin: a new perspective for cultural heritage management and fruition

This paper describes the example of an interesting distance visit approach carried out during the COVID-19 emergency, applied to an underground oil-mill in the town of Gallipoli (Puglia, Italy). The limitations of access for people with disabilities and the complete closure of Italian museums during the emergency have suggested the development of an immersive platform, in the broader perspective of using the output in accordance to digital twin perspectives. Then a tool to support an innovative visit method has been realized: a virtual visit assisted by a real remote guide, hereinafter referred to as "Live-Guided Tour" with e-learning functionality. All this has been made possible starting from a three-dimensional model of an underground oil-mill, from which we extracted the stereoscopic scenes. The stereoscopy is very important for the overall success of the project, because this aspect influences the level of interest, the immersion and the ability to generate emotion and wonder. To the best of Author's knowledge, this is the only system available today for a shared virtual visit for an inaccessible context, which implements many features of a VR visit in a multi-user and multi-platform environment.</p

LECTURA CRITICA DE ESTRUCTURAS SUPERVIVIENTES A PARTIR DE ANTIGUOS ESTUDIOS PARA UNA NUEVA PROPUESTA RECONSTRUCTIVA DEL TEATRO ROMANO DE CATANIA

[EN] The Graeco-Roman theatre of Catania stands in the heart of the historic centre, on the south-eastern slopes of the hill of Montevergine. The building visible today was built during the Julio-Claudian period as part of a programme that saw the rebuilding of the monument, which probably used structures and materials from the earlier Greek theatre. The work undertaken over more than fifty years, involving expropriation, demolition, excavation, and restoration, has, on the whole, made it possible to bring to light the surviving parts of the theatre, improving the comprehension of this monument, despite the fact that some sectors have been irreparably compromised.[ES] El teatro greco-romano de Catania se encuentra en el corazón del centro histórico, en las laderas del sureste de la colina de Montevergine. Visibles en la actualidad el edificio fue construido durante el período Julio-Claudia como parte de un programa que vio la reconstrucción del monumento, lo que probablemente utiliza estructuras y materiales del teatro griego anterior. El trabajo realizado durante más de cincuenta años, la participación de la expropiación, demolición, excavación y restauración, tiene, en general, hecho posible sacar a la luz las partes sobrevivientes del teatro, la mejora de la comprensión de este monumento, a pesar del hecho de que algunos sectores han sido irremediablemente comprometido.Malfitana, D.; Gabellone, F.; Cacciaguerra, G.; Ferrari, I.; Giuri, F.; Pantellaro, C.

Nueva propuesta reconstructiva para una relectura crítica de la documentación arqueológica de Siracusa en época griega

[ES] La reconstrucción de un momumento antiguo está fuertemente influenciada por las lagunas de información, la transcripción incorrecta de las fuentes, las traducciones erróneas y en general las interpretaciones subjetivas que pueden afectar drásticamente al resultado final, generando diferencias significativas entre unas reconstrucciones y otras. Este trabajo tiene como objetivo presentar los resultados de un estudio llevado a cabo para la reconstrucción filológica de algunos monumentos de la Siracusa griega, trantando de resaltar la contribución específica de la arqueología en los procesos de interpretación, con el fin de proponer una presentación eficaz dirigida a un target específico de turistas. Siguiendo este enfoque se ha reconstruido el Templo de Apolo, el conjunto monumental de la Piazza Duomo y el Teatro griego, tratando de dar una salida de pantalla adecuada para consultas efectuadas desde smartphones y coherentes con los objetivos generales del proyecto "PON Energy Smart City". Este proyecto implica un enfoque "inteligente" para visistar Siracusa, centrándose principalmente en la fruición para la adopción de tecnologías basadas en la Realidad Aumentada, la visión de los monumentos de puntos inusuales y la visita virtual multimodal de los puntos de interés. Se desprende de este estudio, la nueva fisonomía de aquellos monumentos que, por diversas razones, se han representado en los últimos años de diferentes formas, muchas de ellas irreconocibles entre sí a pesar de trabajar sobre los mismos elementos. Gracias a la tecnología de restitución basada en imágenes 3D fue posible integrar las partes perdidas de algunos elementos arquitectónicos y escultóricos que prácticamente se trasladaron a su posición original, lo que permite una lectura dinámica que combina el verdadero aspecto con lo virtual.[IT] Lo studio ricostruttivo di un monumento antico risente fortemente di lacune informative, errata trascrizione delle fonti, errata traduzione o peggio ancora, di interpretazioni soggettive che possono compromettere drasticamente il risultato finale, portando a ricostruzioni anche notevolmente diverse tra di loro. Questo lavoro vuole presentare i risultati di uno studio ricostruttivo condotto filologicamente su alcuni monumenti di Siracusa in età greca, cercando di evidenziare il contributo specifico dell'archeologia virtuale nei processi interpretativi, al fine di proporre una presentazione efficace rivolta ad un target specifico di turisti. Seguendo questo approccio sono stati ricostruiti il Tempio di Apollo, il complesso monumentale di piazza Duomo ed il Teatro greco, cercando di fornire output di visualizzazione che fossero adeguati ad una consultazione da smartphone e coerenti alle finalità generali del progetto "PON Energia Smart City". Questo progetto prevede un approccio "smant" alla visita di Siracusa, privilegiando principalmente logiche di fruizione efficiente on-site grazie all'adozione di tecnologie basate sulla Realtà Aumentata, la visione dei monumenti da punti inusuali e la visita virtuale multimodale dei punti di interesse. Emerge da questo studio la nuova fisionomia di quei monumenti che, per motivi diversi, sono stati rappresentati negli anni in forme e modi del tutto differnti, tali da rendere a volte irriconoscibili le diverse ricostruzioni dello stesso oggetto. Grazie alle tecnologie di restituzione 3D basate sull'immagine è stato possibile integrare le parti mancanti di alcuni elementi architettonici e scultorei che, ricollocati virtualmente nella posizione originaria, permettono una lettura dinamica che combina l'aspetto reale con quello virtuale.Un ringraziamento particolare alla dott.ssa Gioconda Lamagna, direttrice del Museo Archeologico Regionale “Paolo Orsi” di Siracusa, per aver concesso il rilievo degli elementi scultorei presentati in questo progettoCaruso, F.; Gabellone, F.; Ferrari, I.; Giuri, F.

METODOLOGÍAS INTEGRADAS PARA UNA NUEVA PROPUESTA RECONSTRUCTIVA DEL ANFITEATRO DE CATANIA

[EN] The roman amphitheatre of Catania stands in a very complex and interesting area where settlement dynamics and transformations have profoundly marked its urban landscape. Over the centuries, the urban and architectural histories together with the formation of the archaeological deposits have led to the complete obliteration of the monument and restricted knowledge of its plan and architectural development. Therefore, it constitutes an interesting context in which to experiment methods and techniques for architectural representation and the three-dimensional reconstruction of the monument[ES] El anfiteatro romano de Catania se encuentra en una zona compleja e interesante donde la dinámica de asentamiento y transformaciones han marcado profundamente su paisaje urbano.

Autism Spectrum Disorder and Duchenne Muscular Dystrophy: A Clinical Case on the Potential Role of the Dystrophin in Autism Neurobiology

Abstract: A diagnosis of autism spectrum disorder is reported in up to 19% of dystrophinopathies. However, over the last ten years, only a few papers have been published on this topic. Therefore, further studies are required to analyze this association in depth and ultimately to understand the role of the brain dystrophin isoform in the pathogenesis of ASD and other neurodevelopmental disorders. In this paper, we report a clinical case of a patient affected by ASD and Duchenne muscular dystrophy, who carries a large deletion of the dystrophin gene. Then we present a brief overview of the literature about similar cases and about the potential role of the dystrophin protein in the neurobiology of autism spectrum disord
