"Ecce Homo" by Antonello da Messina, from non-invasive investigations to data fusion and dissemination
Albertin F., Ruberto C., Cucci C., Callieri M., Potenziani M., Siotto E., Pingi P., Scopigno R., Bettuzzi M., Brancaccio R., Morigi M. P., Castelli L., Taccetti F., Picollo M., Stefani L., De Vita F.
Scientific investigations of artworks are crucial in terms of preservation since they provide a measurable evaluation of the materials and the state of conservation. This is the case of Antonello da Messina's painting "Ecce Homo": its delicate state of conservation, with the need for constant monitoring, required a broad and in-depth diagnostic campaign to support the restorers. The project was carried out entirely in situ using non-invasive cutting-edge techniques and proposes a multimodal and data-centric approach, integrating 3D and 2D methodologies. The surface irregularities and the support were analysed with a structured-light 3D scanner and X-ray tomography. The painting materials were investigated with X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI). Primarily, the data were jointly used for a scientific scope and provided new knowledge of the painting in terms of materials and painting techniques. In addition, two web-based interactive platforms were developed: one to provide restorers and experts with a new perspective of the hidden geometries of the painting, and the other targeted at the general public for dissemination purposes. The results of the Ecce Homo scientific analysis were exhibited, using a touch-screen interface, and developed for different user levels, from adults to kids.Source: Scientific reports (Nature Publishing Group) 11 (2021): 15868–15885. doi:10.1038/s41598-021-95212-2

Documentation and analysis of the deformations of the panel and painted surface with 3D scanner
Pingi P., Siotto E., Palma G., Scopigno R.
Despite what might be assumed, the surface of a painting on a canvas or a wooden panel is not perfectly flat, but rather is characterized by a complex three-dimensionality. The paint the artist lays down on the support possesses its own body and thickness, that, even on a millimeter or sub-millimeter scale, may be detected using instruments and three-dimensional measurement applications. At the same time, a wooden panel may be affected by deformations from historical or restoration changes, which may be readily revealed and documented. When analyzing a work of art subjected to an important restoration treatment, as was the case of the Adoration of the Magi by Leonardo da Vinci, a precise 3D documentation of the painted surface is thus strictly linked to the state of its wooden support. As is well-known, a panel painting is a layered structure (usually a protective varnish coating, paint layers, usually preparatory or ground layers, and the wooden panel), each with different physical and chemical compositions. Therefore, an accurate geometric 3D acquisition of the board structure and its connecting components (butterfly joins or dowel inserts) and the auxiliary support system (crossbars) may supply information to not only improve understanding of how the painting was made and its condition, but also permit it to be monitored over time or during restoration. Furthermore, the application of modern 3D computer graphics technologies is not only a valid diagnostic aid to acquiring knowledge about the work, but also a way to map information and share it (for example art historical information, technical data, and the results of chemical and physical analyses), making them easily accessible online both to experts in the sector and a wider public, thanks to specifically developed multimedia systems.1 In the case of the unfinished masterpiece by Leonardo, a complete high resolution 3D acquisition was performed in order to show and measure--at the moment during conservation treatment--a map of deviations from planarity caused by the curvature and warp of the wooden boards, permitting the documenting of the spatial deformation of the painted surface and the monitoring of its state of preservation.Source: The restoration of Leonardo da Vinci's Adoration of the Magi - Rediscovering a masterpiece, edited by Ciatti M., Frosinini C., pp. 281–286.

Il rilievo 3D per la caratterizzazione morfologica dell'opera di Raffaello
Pingi P., Siotto E., Palma G.
Tra le analisi diagnostiche non invasive effettuate in supporto al restauro della tavola raffigurante Papa Leone X de' Medici tra i cardinali Giulio de Medici e Luigi de' Rossi di Raffaello è stato eseguito un rilievo tridimensionale (3D) dell'intera opera. Il rilievo 3D, oltre ad essere usato per effettuare misure sulla forma della superficie ed essere un valido supporto per la conoscenza e lo studio dell'opera, si configura anche come un efficace mezzo per monitorarne lo stato di conservazione nel tempo. In questo caso, l'acquisizione 3D era volta alla valutazione della deformazione del supporto ligneo e allo studio del deterioramento della superficie pittorica. Per tale motivo l'intera opera (fronte, retro e bordi) è stata acquisita con un passo di campionamento medio pari a 0.3 mm. Alcune zone sono state acquisite anche ad una risoluzione di 0.16 mm al fine di mettere a punto un metodo automatico in grado di evidenziare le micro-fratture dello strato pittorico.Source: Raffaello e il ritorno del Papa Medici: restauri e scoperte sul Ritratto di Leone X con i due cardinali, edited by Marco Ciatti, Eike D.

Deformation analysis of Leonardo da Vinci's "Adorazione dei Magi" through temporal unrelated 3D digitization
Palma G., Pingi P., Siotto E., Bellucci R., Guidi G., Scopigno R.
3D scanning is an effective technology for dealing at different levels the state of conservation/deformation of a panel painting, from the micro-geometry of the craquelure to the macro-geometry of the supported used. Unfortunately, the current solutions used to analyze multiple 3D scans acquired over time are based on very controlled acquisition procedures, such as the use of target reference points that are stationary over time and fixed to the artwork, or on complex hardware setups to keep the acquisition device fixed to the artwork. These procedures are challenging when a long monitoring period is involved or during restoration when the painting may be moved several times. This paper presents a new and robust approach to observe and quantify the panel deformations of artworks by comparing 3D models acquired with different scanning devices at different times. The procedure is based on a non-rigid registration algorithm that deforms one 3D model over the other in a controlled way, extracting the real deformation field. We apply the method to the 3D scanning data of the unfinished panel painting "Adorazione dei Magi" by Leonardo da Vinci. The data were acquired in 2002 and 2015. First, we analyze the two 3D models with the classical distance from the ideal flat plane of the painting. Then we study the type of deformation of each plank of the support by fitting a quadric surface. Finally, we compare the models before and after the deformation computed by a non-rigid registration algorithm. This last comparison enables the panel deformation to be separated from the structural changes (e.g. the structural restorations on the back and the missing pieces) of the artwork in a more robust way.Source: Journal of cultural heritage 38 (2019): 174–185. doi:10.1016/j.culher.2018.11.001

Three Armenian Manuscripts from Tuscany
Callieri M., Pingi P., Potenziani M., Ponchio F., Scopigno R.
For the temporary exhibition "Three Armenian Manuscripts from Tuscany", taking palce at the Matenadaran Museum (Jerevan, Armenia) from June 9th 2019 to January 9 2020, The Visual Computing Lab of ISTI-CNR created a multimedia interactive kiosk presenting to the museum visitors the pages of the codices and the rooms of the libraries that preserved the books in their long life. The photographic campaign of the codices and buildings has also been used in the monographic volume "Three Armenian Manuscripts from Tuscany (13th - 14th century)", by Anna Rita Fantoni e Giovanna Rasario. Mandragora, Firenze. 2019. ISBN 978-88-7461-475-2 The Kiosk presents, commented by the texts edited by the experts Anna Rita Fantoni e Giovanna Rasario, high-res 360° panorama images of ther libraries (Biblioteca Medicea Laurenziana and Biblioteca di S. Matteo), high-res images of selected pages of the three codices displayed int he exhibition, and relightable RTI images of the decorated cover of one of the codices and of a parchment page illuminated in gold. The Kiosk is based on web technologies: this makes possible the installation on a stand-alone PC (like in the exhibition) but also a web publishing, linked just above. The generation of RTI, and the web visualization of RTI and multiresolution images is managed by the library Relight, developed by ISTI-CNR.

Rilievo 3D di Alchimia, ed uso dei modelli 3D per studio e divulgazione
Callieri M., Dellepiane M., Lureau A., Pavoni G., Pingi P., Potenziani M., Scopigno R.
Le tecniche di digitalizzazione 3D si sono fatte largo prepotentemente nel campo dei beni culturali. Dalle prime sperimentazioni dell'utilizzo di modelli 3D di due decenni fa, si è arrivati oggi ad una ampia diffusione e democratizzazione di queste tecnologie, fino a poter dire che la digitalizzazione 3D è uno strumento ormai essenziale nella maggior parte dei progetti di conservazione, restauro, documentazione e studio dei beni culturali. Nell'ultimo periodo, poi, anche le tecnologie di riproduzione fisica da modelli 3D (3D printing e la prototipazione rapida) stanno entrando nella routine di queste tipologie di azione. Un aspetto chiave dei modelli digitali 3D risiede nella loro "doppia natura": -i modelli 3D sono pura informazione numerica e geometrica, sono fatti, cioè, di numeri che rappresentano le misure e la forma di un oggetto fisico. Hanno dunque proprietà metriche, e le misure in essi contenute possono essere usate per calcoli tecnici, documentazione, simulazione e riproduzione fisica; -i modelli 3D però hanno anche un aspetto "visuale", cioè possono essere visualizzati e disegnati a schermo formando immagini che, visivamente, corrispondono alla percezione che noi avremmo davanti all'oggetto reale (specialmente quando il modello 3D geometrico è corredato anche di informazione di tessitura o colore). Questa doppia natura unisce una precisione, una scientificità del dato, alla possibilità di interagire con esso in maniera naturale, come faremmo con l'oggetto reale. Se è vero che nelle prime sperimentazioni, i modelli 3D sono stati utilizzati solamente come fonte di misure e di dati, oppure solo come "gadget visuale" per presentare al pubblico l'oggetto d'arte, possiamo dire che oggi, con il progredire delle tecnologie, e soprattutto con la definizione di protocolli di lavoro più completi, questi due aspetti riescono ad essere sfruttati appieno in maniera congiunta. In questo lavoro, per l'appunto, è stato possibile sfruttare appieno le potenzialità del media digitale 3D, sia dal punto di vista scientifico-documentale, che come strumento di disseminazione e di coinvolgimento del pubblico.Source: Alchimia di Jackson Pollock - Viaggio all'interno della materia, edited by Luciano Pensabene Buemi, Francesca Bettini, Roberto Bellucci, pp. 145–154.

Documentazione e analisi delle deformazioni del supporto ligneo e della superficie pittorica mediante rilievo 3D
Pingi P., Siotto E., Palma G., Scopigno R.
Un dipinto su tela o su tavola, contrariamente a quanto si potrebbe pensare, non è un oggetto con una superficie perfettamente planare, ma è caratterizzato da una complessa tridimensionalità. Il colore che l'artista pone sul supporto ha una propria corposità materica, uno spessore, che, seppur millimetrico o sub-millimetrico, può essere rilevato con strumenti e applicativi di misurazione tridimensionale (3D). Allo stesso tempo, il supporto ligneo può presentare deformazioni legate a vicissitudini storiche e conservative, che possono essere facilmente rilevate e documentate. Nella fase di analisi di un'opera soggetta ad un importante intervento di restauro, come è avvenuto per l'Adorazione dei Magi di Leonardo da Vinci, un'accurata documentazione 3D della superficie pittorica è pertanto strettamente legata a quella del suo supporto ligneo. Pertanto, una scrupolosa acquisizione geometrica 3D del tavolato e dei suoi elementi di collegamento (farfalle e cavicchi) e di sostegno (traverse) può fornire elementi utili non solo per una maggiore conoscenza della fattura dell'opera e del suo stato di conservazione, ma anche per un suo monitoraggio nel corso del tempo o in fase di restauro. Inoltre, un uso appropriato delle moderne tecnologie di Computer Grafica 3D non rappresenta soltanto un valido ausilio diagnostico per la conoscenza dell'opera, ma anche un mezzo per raccogliere informazioni di carattere scientifico-divulgativo (ad esempio dati storico-artistici, tecnici, risultati di analisi chimico-fisiche) e renderle facilmente fruibili on-line agli addetti del settore e ad un pubblico più vasto, grazie a sistemi multimediali appositamente sviluppati. Nel caso del capolavoro non concluso di Leonardo, una sua completa acquisizione 3D ad alta risoluzione è stata eseguita con lo scopo di evidenziare e misurare - in fase di restauro pittorico - una mappa di deviazioni della planarità causata dalla curvatura e deformazione delle tavole lignee, consentendo di documentare la deformazione spaziale subìta dalla pittura e monitorare il suo stato di conservazione.Source: Il restauro dell'Adorazione dei Magi di Leonardo - La riscoperta di un capolavoro, edited by Marco Ciatti, Cecilia Frosinini, pp. 281–286.

A virtual experience across the buried history
Canzoneri A., Pavoni G., Callieri M., Dellepiane M., Pingi P., De Giorgi M., Scopigno R.
The Sant'Angelo cave church is an underground medieval Benedictine complex in the south of Italy, affected by serious structural and chemical degradation. In the context of a documentation campaign promoted by the local Superintendence and supported by the IPERIONCH. it project, we carried out an accurate 3D and photographic survey, and reconstructed a detailed 3D model of the site (encoding shape and colour). While the primary purpose of this large amount of collected data was to provide a metric documentation of the site, the completeness and the high detail of the survey suggested also a possible use for dissemination and virtual presentation. Thus, we exploited the 3D digital models to design and build a virtual visit of the church, oriented to scholars, museums and tourists. This paper describes the design and implementation of this educational experience, closely related to the bibliographic sources of the artistic heritage, fully enriched with hyper-textual information, intuitive and easy to use for all users regardless of their level of familiarity with the 3D medium.Source: AVR 2016 - Augmented Reality, Virtual Reality, and Computer Graphics.

Fast and simple automatic alignment of large sets of range maps
Pingi P., Corsini M., Ganovelli F., Scopigno R.
We present a very fast and simple-to-implement algorithm for the automatic registration of a large number of range maps. The proposed algorithm exploits a compact and GPU-friendly descriptor specifically designed for the alignment of this type of data. This pairwise registration algorithm, which also includes a simple mechanism to avoid to get false positives, is part of a system capable to align a sequence of up to hundreds of range maps in few minutes. In order to reduce the number of pairs to align in the case of unordered range maps we use a prioritization strategy based on the fast computation of the correlation between range maps through FFT. The proposed system does not need any user input and it was tested successfully on a large variety of datasets coming from real acquisition campaigns.Source: Computers & graphics 47 (2015): 78–88. doi:10.1016/j.cag.2014.12.002

Alchemy in 3D: a digitization for a journey through matter
Callieri M., Pingi P., Potenziani M., Dellepiane M., Pavoni G., Lureau A., Scopigno R.
In this work, we will present the outcomes of the 3D diagnostic investigations carried out on the painting Alchemy by Jackson Pollock. Thanks to an accurate digitization and a careful processing, we were able to generate a very precise high-resolution 3D model that proved to be useful in different stages of the diagnostic and conservation campaign. The 3D model was integrated in the conservation process, along with the other diagnostic investigations; the geometric data was also used to produce images and video sequences for dissemination purposes. The most interesting aspect of the work, however, was the idea of going beyond photo-realism and the use of the scanner-measured geometry to try to interpret and understand the traces and signs on the surface of the painting, in relation with the gestures and techniques used by Pollock while painting this masterpiece. Combining the knowledge of the curators and the metric data gathered in the digitization, we were able to discover and validate several interesting aspects of the painting, in the direction of trying to better understanding the painting process which was, in the idea of the artist, an essential part of the artwork. The 3D model of the artwork played a central role also in the temporary exhibition created for the dissemination of the conservation and the diagnostic campaign to the museum visitors. This was also done following the idea of using the geometry to explain the gestures, actions and techniques of Jackson Pollock at work. The 3D model was used to create an interactive kiosk, to have the visitors navigate the model and access explanations of relevant geometrical details and to produce a 1:1 physical reproduction to give the public the possibility to physically interact with the artwork.Source: International Congress on Digital Heritage, pp. 223–231, Granada, Spain, 28/08/2015-02/10/2015

Digitizing and navigating unaccessible archaeological sites on mobile devices
Malomo L., Banterle F., Pingi P., Callieri M., Dellepiane M., Scopigno R.
A very large number of sites, probably the large majority of our Cultural Heritage (CH), are unaccessible to the public due to the lack of infrastructure, improper security conditions or lack of personnel. Digitizing in 3D those sites is not very complicated nowadays. We will briefly review the technology available for cheap 3D digitization, from 3D scanning to cheaper photogrammetric solutions. However, digitization per se is not a solution: 3D models have to be shared in the widest and easiest manner. We will present the design and results of a software instrument that aims at supporting easy navigation of 3D digitized spaces, running on top of mobile devices such as tablets or smartphones. The main goal of this project is to guarantee navigation with ease for users without experience in computer graphics and videogames, while providing high-fidelity rendering of the digital 3D model.Source: 1st International Conference on Metrology for Archaeology, pp. 43–48, Benevento, Italy, 22-23/10/2015

VirtualTour: a system for exploring cultural heritage sites in an immersive way
Malomo L., Banterle F., Pingi P., Gabellone F., Scopigno R.
In the last few years, mobile or wearable virtual reality has gained new interest amongst the industry and researchers. The rapid development of new technologies such as high quality head mounted displays, accurate and cheap motion sensors (e.g. accelerometers, gyroscopes, depth cameras, etc.), localization sensors (e.g. GPS, compass, etc.) etc. have led to new opportunities that just a few years ago were not possible to achieve with off-the-shelf components. This renaissance of virtual reality is happening in both research and practical applications, such as computer games, movies, documentaries, learning, urban planning, etc. In this work we propose a system, VirtualTour, offering virtual exploration of Cultural Heritage (CH) sites on mobile devices based on a natural interaction approach; a few easy to understand (and to be tracked) actions performed by the user in the real world are translated into navigation instructions in the virtual world. To achieve this goal, we have exploited embedded sensors and the fast hardware of modern mobile devices.Source: 2015 Digital Heritage International Congress, pp. 309–312, Granada, Spain, 28/09/2015-02/10/2015

From the archival documentation to standardised web database and 3D models: the case study of the Camaldolese Abbey in Volterra (Italy)
Siotto E., Callieri M., Pingi P., Scopigno R., Benassi L., Parri A., La Monica D., Ferrara A.
Our age is characterized by the ease of communication and fast and free exchange of data. The use of standards and a common approach to recollect, organize and present the documentation gives a great advantage for the knowledge and dissemination of the archaeological, artistic, historical and conservation information of Cultural Heritage. Establishing a "correct" documentation policy is the main goal that guided our initiative for the documentation, preservation and valorisation of the monumental complex of the Camaldolese Abbey in Tuscany. In this project we retrieved the paper documentation in the Historical Archives of the Tuscany Region, to study the historical and conservation data of the monumental complex. Digital technologies have been used to support storing and access to this important information, including also data to monitor the current state of its preservation. The documentation has been digitized and is accessible through a web database; this resource was designed by following the Italian National standards proposed by Central Institute for Cataloguing and Documentation (ICCD). The current state of conservation of some parts of the building has been documented by taking panoramic images or panoramas (360º images) and by the acquiring 3D digital models. In particular, panoramas are used to document the state of preservation of frescoed rooms, while geometric 3D models are produced to document the degraded areas of the church, which require a constant monitoring. Moreover, an analytical virtual reconstruction of the church was modeled to depict its status before the building's collapse. The main goals of this work are to provide a good-practice example on how to document and disseminate on the web the knowledge available on an endangered monument, following national and international standards, in order to make the knowledge widely accessible. In this way, it is possible to disseminate and enhance the old results with new analysis and interpretations of documents that can be easily shared with other researches, conservation experts and the ordinary public.Source: CHNT 18 - International Conference on Cultural Heritage and New Technologies, Vienna, Austria, 11-13 November 2013

The Reconversion of Italian fortress through the use of modern tools
Parri A., Benassi L., La Monica D., Siotto E., Callieri M., Pingi P., Scopigno R.
The Italian historic architectural heritage includes a special and widespread category of buildings: the fortresses. Fortresses characterized for centuries the image of many Italian towns and landscapes and their presence modelled their urban or rural settings. Today these military buildings have lost their original function and very often create difficulties in current urban policies, in consideration of their dimensions, their collocation and the high costs for their preservation. As consequence, they are often in critical conditions of conservation and they have been frequently transformed in empty spaces disconnected from the current city life. The better way to protect these huge architectures consists in a long-term planning of sustainable reuse. Obviously these structures cannot be used to fulfill their original military functions and their peculiar architectural features clash sometimes with actual needs. It is necessary to study each structure according to its environmental, social and cultural contest to facilitate its best reconversion. The use of multimedia instruments suggests a method to reach satisfactory results but also it engenders some questions and doubts. The goal of this paper is to analyze the problem of fortresses today and to explain some meaningful cases of reuse in central Italy. Particular attention will be paid to the fortress of Verrucole near Lucca. This is an emblematic case study both for the choices of restoration and new display and for the difficulty to select new functions.Source: Heritage Architecture Landesign, focus on Conservation, Regeneration, Innovation.

Virtual reconstruction of an Etruscan tomb
Batino S., Callieri M., Duranti D., Dellepiane M., Pingi P., Siotto E., Scopigno R.
This paper describes the main phases of an ongoing project regarding the 3D virtual reconstruction of an Etruscan hypogeum together with the funerary equipment it contained. The tomb is dating back to late Hellenistic period. It was discovered in 1880 in Sigliano, between lake Trasimeno and lake of Chiusi in Central Italy. This sepulcher is a paradigmatic testimony to enlighten the processes of settlement and land use during ancient times in a district (Valdichiana) with a strong vocation for agriculture and forestry. Furthermore, this reconstruction allows to relocate in their original context some finds now kept at the Archaeological Museum of Perugia, together with some other lost goods, documented by detailed sketches and drawings only. Hence, 3D modeling and 3D scanning have been combined to present the plausible appearance of the tomb when it was discovered. Some of the most interesting objects have been 3D scanned to provide accurate data. Particular care has been devoted to the 3D model of a probably gilded bronze helmet, a Southern Italy production (probabl y from Taranto) dated 4th century BC. A portion of plausible landscape has been modeled taking into account the geomorphology obtained through Google Earth, to locate the grave, and to insert it in a possible context. Moreover, following the indications found in the original sketches, the interior of the tomb and some of the smaller objects have been modeled. All of the generated data have been used to produce a video which will be shown at the Archaeological Museum of Perugia.Source: CHNT 2012 - Conference on Cultural Heritage and New Technologies, Vienna, 5-7 November 2012
