The Petralona Cave, which local inhabitants discovered by chance in 1959, is a remarkable natural and cultural landmark close to the village of Petralona, in the Chalkidiki peninsula of Greece. The site has gained global recognition for the discovery of a remarkably well-preserved Palaeolithic human skull, unearthed in 1960; it also holds archaeological and palaeontological significance. In this paper, the researchers introduce the Petralona Cave Virtual Museum: an innovative project whose mission is to increase public awareness and comprehension of the site. Our approach goes beyond mere replication of the physical museum located close to the cave; instead, the objective is to create an independent and comprehensive experience that is accessible to all visitors, irrespective of their ability to visit the site in person. Our methodology involved the documentation of the site and its history, analysis of user requirements, development of use cases to steer the design process, as well as architectural designs creation, itineraries and findings digitisation, and architectural structure finalisation. The Virtual Museum provides a well-organised frame structure that serves as an efficient gateway to the content, making navigation easy for visitors. Thanks to various presentation methods, including videos, high-quality images, interactive maps, animated content, interactive 3D models, plus searchable item libraries, among others, users are empowered to create a highly personalised navigation plan; thus the Virtual Museum experience is comparable to visiting the physical museum or cultural site. Cutting-edge digitisation techniques were employed to create highly detailed 3D models of the site. The Petralona Cave Virtual Museum is expected to offer an immersive experience, engaging diverse audiences; the interactive and educational exploration provides highly innovative access to archaeological knowledge. The visibility of the Petralona site is amplified and there is a significant contribution to knowledge dissemination about this important cultural heritage site.

Highlights: • Graphic tools and virtual reconstruction applied to watermills contribute to their overall understanding as an anthropogenic landscape. • Virtual reconstruction of the milling mechanisms allows us to understand the mill operation beyond the mere construction preservation. • The Riamonte mills are an example of a group of canal mills linked to a single dam and with a social typology of inheriting turns to grind. Abstract: Each concello (municipality) in Galicia is home to a large number of pre-industrial rural heritage assets integrated into the landscape. Among them are the water mills, usually made up of small constructions that are difficult to reuse in their original function. They are not easily compatible with other uses either. Their current state of abandonment requires their cataloguing and correct valorization as pre-industrial archaeological heritage. These constructions must be conceived as interrelated constructive groupings, in their original physical and social context. A good example of this is the unpublished sample of the Riamonte milling complex. Its study, digitalization and virtual recreation by means of computer-assisted graphics have great potential for dissemination to the public and better integration into the nature trail near the riverbed. Graphically presenting archaeological heritage through virtual media helps to promote social understanding in order to raise awareness of the importance of its protection and irreplaceable nature, especially in case of those vestiges lacking sufficient security to survive. Due to the large amount of vegetation around the wall remains, a rigorous planimetric survey of the entire complex was carried out, followed by three-dimensional (3D) modelling of representative elements. In addition, applying a rigorous principle of transparency, a chromatic differentiation is made in the 2D and 3D virtual reconstructions between already existing and newly added elements. Regarding the 3D model, a historical-archaeological evidence scale is used, allowing a graphic identification of the authenticity degree required to provide reliability in the reconstruction of lost or altered parts. This facilitates virtual recreation interpretation among future researchers from different disciplines. The Riamonte mill complex is part of a typology typical of the region, in which the use of virtual models makes it possible to reach the scales of the territory, the building and the machinery, facilitating the correct understanding of this cultural heritage.

The research presented here puts together different direct and/or physical operations all aimed to enhance the knowledge and produce advanced dissemination of the very last ship from the “Mosquitos’ Fleet” which operated during the World War I and in some operations even during the World War II. The exploration of the valuable remains along the Thames River in London, the intervention with archaeology strategy, the use of digital survey procedures, the investigation of the references about the fleet, the digital modelling and drawing and the final online sharing of the 3D model, brought together to a specific digital heritage creation of an element with a high risk of getting lost. An international team worked together on the poor shipwreck of the Eothen (the last name assigned to this ship by its last owner). The intervention was operated in very odd operative conditions, with the hull invaded by the mud, the very wet environment and the daily flood of the area, such a mix of difficult conditions were a special challenge for the survey operations, which were optimized and accurately planned to allow the best and efficient result in terms of coverage and level of details. The following post-processing aimed to the production of a classic set of 2D drawings and an interactive 3D model, accessible in a real-time visualization from the sketchfab.com platform creates an excellent base for a possible following restoration/musealisation intervention, or, at least, allow digital preservation of a rich dataset of the remains of this interesting piece from the naval history of the first half of the 20th century. Highlights: • The “mosquito fleet” has a specific page in the WWI naval wars. Based on a specific ship, it is missing detailed documentation, the survey of the last one can highlight that episode. • The digital survey of the Eothen has a strategy aimed to allow the full documentation of the shipwreck in a very difficult environment, managing floods, mud, vegetation and reflections. • The drawings and the 3D model, accessible from a free platform allow complete access to this ruined ship, a contribution to knowledge and a base for possible intervention hypothesis.

Can we preserve cultural heritage and, consequently, the memory of the past? To answer this question, one should look at the digital revolution that the world has gone through in recent decades and analyse the complex and the dialectical relationship between cultural heritage and new technologies. Thanks to these, increasingly accurate reconstructions of archaeological sites and historical monuments are possible. The resulting digital replicas are fundamental to experience and understand cultural heritage in innovative ways: they have complex and dynamic relationships with the original objects. This research paper highlights the importance and the scientific validity of digital replicas aimed at understanding, enhancing and protecting cultural heritage. The study focuses on the virtual reconstruction of the constructive phases, from the mid-15th century to date, of one of the most emblematic Gothic-Renaissance buildings in the city of Milan (Italy): the convent of Santa Maria delle Grazie, famous worldwide for hosting Leonardo da Vinci's Last Supper painting. This site proved to be an ideal case study because of its troubled and little-known history that led to numerous changes over the centuries. Thanks to a methodological approach based on the analysis of the documentary sources and three-dimensional (3D) modelling, it was possible to outline the chronological succession of the convent transformations; the way in which these overlapped the pre-existing structures was described starting from the Renaissance harmonious and organic interventions, to finally reach 18th-19th centuries inhomogeneous and incompatible additions. Finally, the research was completed by mapping the 3D models based on the sources used and their different levels of accuracy. The 3D models have thus become a valid tool for checking and verifying the reconstruction hypotheses. Highlights: • The study focused on the virtual reconstruction of the convent of Santa Maria delle Grazie, one of the most emblematicGothic-Renaissance buildings in the city of Milan. • By combining data from documentary sources, architectural treatises, period photos and digital survey, the mainbuilding phases of the convent, from the 15th century to date, were digitally reconstructed. • The 3D models are enriched with information about the accuracy of the digital reconstruction, creating 3D databasesthat can be easily consulted and updated.

The Portes Mordelaises, remnants of the medieval city walls of Rennes, France, has been the subject of several archaeological excavations until 2017. From these excavations, we created a three-dimensional (3D) model of the site reconstructed as it would have appeared during the 15th century, including the surrounding plus the interiors of its famed towers. Once our efforts and results were officially recognised as being of national interest by the French Ministry of Culture and Communication, Department of Heritage and the National Museum Service of France, we presented our virtual model reconstruction in an exhibition curated by the Museum of Bretagne, entitled "Rennes, les vies d'une ville" (Rennes, the Lives of a City). This approach to 3D reconstruction of the site served to further study Rennes’ origins, its construction, organisation, as well as its historic relationship to surrounding territories. The main objective of this work was to investigate, using of a significant and complex archaeological site as proof of concept, how the digitalisation of an existing structure, the modelling of its hypothetical structures, and the interactions with its virtual spaces enabled the general public to provide critical feedback, and enhance archaeological knowledge and evaluation of such sites. This reconstruction was carried out under a West Digital Conservatory of Archaeological Heritage project, whose mission is to support and advise archaeologists in the production and exploration of 3D archaeological datasets using the latest digitisation, modelling, and virtual reality (VR) techniques. Through a complex but repeatable process, using the valuable data provided by various excavations, in addition to new information provided by the 3D digitalisation itself, we produced a 3D model, fully satisfactory to rigorous scientific standards, which was then incorporated into a VR space ready for diffusion to the general public. Furthermore, the fact that 45850 visitors were welcome to experience our 3D model at an exhibition in a city the size of Rennes proved to be a significant success.

The dissemination of the tangible and intangible values of heritage building represents one of the most important objectives in the field of Digital Cultural Heritage (DCH). In recent years, different studies and research applied to heritage monuments have shown how it is possible to improve the awareness of the architectural heritage through the integration of latest developments in the field of 3D survey, 3D modelling, Building Information Modeling (BIM) and eXtended Reality (XR). On the other hand, this digital workflow requires a huge amount of data sources and a holistic approach to reach a high level of information sharing coming from different disciplines and sectors such as restoration, geomatics, 3D virtual museums and serious gaming. In conjunction with entertainment software and gaming, this research shows the main results obtained during the generative process of digital environments oriented to improve the level of information and to enrich the contents coming from the informative models. The case study is represented by one of the most important Lombard monuments: the Basilica of Sant’Ambrogio in Milan. This study, starting from the 3D survey and the data collection of the historical records of the church, improves the creation of an XR experience that reaches a new level of interactivity for different types of devices (desktop, mobile, VR headset) and users (experts, non-experts). Highlights: • Generative modelling requirements and novel grades of generations (GOG) and accuracy (GOA) are presented in order to improve the digitisation of built heritage from the 3D survey, reducing time and costs of the scan-to-BIM process. • The holistic value of generative modelling allows experts to create digital worlds able to faithfully and accurately represent the detected reality and improve new immersive environments for Virtual Reality (VR) and Augmented Reality (AR) projects. • Immersive environments are created with a mixture of the latest generation software and hardware, allowing users to discover the hidden historical values of built heritage with new levels of interactivity and information.

3D modelling of archaeological and historical structures is the new frontier in the field of conservation science. Similarly, the identification of buried finds, which enhances their multimedia diffusion and restoration, has gained relevance. As such sites often have a high level of structural complexity and complicated territorial geometries, accuracy in the creation of 3D models and the use of sophisticated algorithms for georadar data analysis are crucial. This research is the first step in a larger project aimed at reclaiming the ancient villages located in the Greek area of southern Italy. The present study focuses on the restoration of the village of Africo (RC), a village hit by past flooding. The survey began with a laser scan of the church of St. Nicholas, using both the Faro Focus3D and the Riegl LMS-Z420i laser scanner. At the same time, georadar analyses were carried out in order to pinpoint any buried objects. In the processing phase, our own MATLAB algorithms were used for both laser scanner and georadar datasets and the results compared with those obtained from the scanners’ respective proprietary software. We are working to develop a tourism app in both augmented and virtual reality environments, in order to disseminate and improve access to cultural heritage. The app allows users to see the 3D model and simultaneously access information on the site integrated from a variety of repositories. The aim is to create an immersive visit, in this case, to the church of St. Nicholas. Highlights: • Use of different algorithms for registration of terrestrial laser scans and analysis of the data obtained. • 3D acquisition, processing and restitution methodology from georadar data. • Implementation of a tourist app in both virtual and augmented reality by integrating geomatics methodologies.

Entre ellos se encuentran los molinos hidráulicos, constituidos habitualmente por pequeñas construcciones difícilmente reutilizables en su función original; tampoco son fácilmente compatibles con otros aprovechamientos, cuyo estado de abandono hace necesaria su catalogación y correcta puesta en valor como patrimonio arqueológico previo a la industrialización. Estas arquitecturas deben ser entendidas en la forma de agrupaciones constructivas interrelacionadas, en su contexto físico y social de origen. Buen ejemplo de ello es la muestra inédita del conjunto molinar de Riamonte. Su estudio, digitalización y recreación virtual mediante medios gráficos asistidos por ordenador atesora un gran potencial para su difusión al público y una mejor integración en la senda turística de naturaleza próxima al cauce del río. Dar a conocer gráficamente el patrimonio arqueológico a través de medios virtuales contribuye a favorecer la comprensión social en aras de sensibilizar y concienciar sobre la importancia de su protección y naturaleza irremplazable, en especial aquellos vestigios carentes de la suficiente seguridad de supervivencia. Debido a la gran cantidad de vegetación alrededor de los restos murarios se optó por realizar un riguroso levantamiento planimétrico de todo el conjunto y, posteriormente, el modelado tridimensional (3D) de elementos representativos. Además, siguiendo un riguroso principio de transparencia, se lleva a cabo una diferenciación cromática en las reconstrucciones virtuales en 2D y 3D entre elementos existentes y añadidos. En el caso del modelo 3D se aplica una escala de evidencia histórico-arqueológica que permite una identificación gráfica del grado de autenticidad, necesaria para dotar de fiabilidad a la reconstrucción de las partes perdidas o alteradas. De esta forma se facilita la labor en la interpretación de las recreaciones virtuales entre los futuros investigadores de diferentes disciplinas. El conjunto molinar de Riamonte forma parte de una tipología propia de la región, en la que el uso de modelos virtuales permite alcanzar las escalas del territorio, del edificio y de la maquinaria, facilitando la correcta comprensión de este patrimonio cultural.

This article aims to critically examine the entire methodology of very large scale (1:1) surveying and documentation of mosaic surfaces. The term ‘survey’ should be read in its broadest and most complete and sense, including the phases of measurement and data processing as well as management and use of these data for the purposes of preservation and maintenance. The case study presented here took place at St Mark’s Basilica (Basilica di San Marco), in Venice, where mosaic flooring, wall and vault decorations have been surveyed on two separate occasions. These two experiences shared a common goal (a full-scale survey of the mosaic decorations) but differed in terms of the methodologies used, chiefly due to the technological developments of recent years. All this, therefore, lends itself to a methodological reflection and critique of the ways in which surveying technology has evolved over time. It enables to conduct surveys that would, just a few years ago, have been inconceivable due to their size and complexity. This article describes in detail current surveying processes, which includes the use of a multi-scale “image-based” approach, “re-topology” methods such as non-uniform rational B-spline (NURBS) and a tailor-made Building Information Modeling (BIM) system. This system allows the direct use of a three-dimensional (3D) model of the Basilica within the maintenance process of the monument itself with the options to georeferencing information, extract basic metric data and catalogue all its mosaics. Highlights: • Modern digital photogrammetric techniques enable the acquisition of very complex objects, not only in terms of form but also in terms of material. • To obtain high resolution orthophotos, it is necessary to accurately take care of all the stages of the process: photographic acquisition, surveying, modelling and orthographic reprojection. • High resolution images and detailed 3D models can benefit from a complex BIM system for the management of all data.

Unmanned aerial vehicle (UAV) photogrammetry has shown a very rapid development in many fields, especially in archaeological excavation areas and architectural complexes, where it offers a detailed generation of three-dimensional (3D) data including the possibility of updating over time. It also proves to be a very flexible tool applicable to many types of complex areas with a variety of different features. The use of aerial acquisition provides highly effective results, adding to both rapid capture and lower costs. In fact, today in the field of archaeological research, great efforts are invested in the generation of very large-scale models and orthophotos, and the technology seems to promise further future developments, not only from the terrestrial (orthogonal) point of view, but also from the nadiral direction from a low altitude, as a preferential and often optimal point of view. Here an effective workflow for photogrammetric product generation is presented for selected case studies in some monumental areas of ancient Hierapolis in Phrygia (Turkey), in which the Italian Archaeological Mission of Hierapolis (MAIER) has been working since the 1960s. The recent experiences achieved by UAV photogrammetry are quite innovative. The variety and complexity of the buildings, as well as the height of their ruins, offer numerous challenges, which are interesting to deal with. The 3D aerial survey was performed for multiple purposes with the eBee system by Sensefly. Specific attention was paid to the digital surface model (DSM) and aerial orthoimages of three test areas: the Plutonium area; the Thermal Bath-Church; and the Necropolis. Starting from the same technical approach, a comparative assesment among the three sites was carried out, taking into account the specific goals, the type of the structure and the terrain conformation.

The three-dimensional (3D) visualization of historical and cultural heritage in the province of Cáceres is essential for tourism promotion. This study uses panoramic spherical photography and terrestrial laser scanning (TLS) for the geometric characterization and cataloguing of sites of cultural interest, according to the principles of the Charter of Krakow. The benefits of this project include improved knowledge dissemination of the cultural heritage of Cáceres in a society that demands state-of-the-art tourist information. In this sense, this study has three specific aims: to develop a highly reliable methodology for modeling heritage based on a combination of non-destructive geomatics methods; to design and develop software modules for interactive 3D visualization of models; and to promote knowledge of the historical and cultural heritage of Cáceres by creating a hypermedia atlas accessible via the Internet. Through this free-of-charge hypermedia atlas, the tourist accesses 3D photographic and interactive scenes, videos created by 3D point clouds obtained from laser scanning and 3D models available for downloading in ASCII format, and thus acquire a greater knowledge of the touristic attractions in the province of Cáceres.

Cultural heritage is a relevant issue in contemporary society. While its preservation is a challenge, its dissemination, can contribute for an economic balance between costs and benefits. Scientific heritage can be considered as a special domain of cultural heritage, not yet sought by the mass tourism, but worth being preserved as the roots of today’s knowledge. Considering that university students of engineering and computer science traditionally do not address cultural or scientific heritage issues in their syllabus, and that they constitute a layer of young citizens that will come to be influential in the future of society, an effort was undertaken to focus on this theme in disciplines of different courses, allying the learning of technical skills with the natural interest of younger people for 3D and animation for the profit of heritage. The goal was to raise the awareness of this particular group to the importance of maintaining heritage issues, in particular, in a virtual way, both for documentation and for divulgating their existence. Raising funds for buildings’ restoration, attracting the public to visit buildings and collections that are outside the usual tourism routes, contributing to revenue generation, or allowing virtual visits of not accessible issues, complementing physical visits on site, were the general aims of the proposed projects. A survey was undertaken under the participating students to evaluate how the projects influenced their attitude towards heritage. The obtained feedback was very positive: 76% agreed that the project alerted them for the importance of preserving historical and cultural heritage, while 72% considered it was interesting that the topic of digital cultural heritage was used for the assessments of the disciplines.

The initial construction of a digital virtual object is the three-dimensional (3D)point. Using the notions of making, wayfaring, meshwork and agency, this discussion focuses on Ingold’s (2011) theoretical approach to these comments as a means for the construction of archaeological knowledge as applied to the 3D virtual landscape. It will demonstrate that 3D points, whether constructed or captured, can be considered to be agents within an actor network, have agency and are subject to memory and loss within the digital archaeological record. By their interconnections they become a mesh work that can exchange and retain unique attributes of materiality. As such, they challenge our notions of meaning-making beyond the rote actions of visualizing within archaeology to a form that is more theoretically deeper. By viewing the construction and capture and the production of 3D or 2D visual data through a different lens but within theoretical archaeological terms, we can begin to understand our role in the creation of meaning within virtual archaeology.

In ancient Rome, damnatio memoriae was a practice of erasing the memory of condemned persons from historical records after their death. This practice was usually addressed by the Senate to Roman elites and emperors who were declared enemies of the State, in order to preserve the honour of Rome. This condemnation usually included practices such as, for example, the erasure of names sculpted on inscriptions and the destruction or reworking of statues and of any other image of the person. Emperor Nero, for example, was condemned to this practice immediately after his death and a wide iconographic repertoire on him was therefore destroyed or deeply damaged. This lack of information can actually be improved thanks to the possibilities of virtual restoration and reconstruction offered by 3D digital technologies. The aim of this paper is to show how the possibility to acquire 3D reality-based data from archaeological finds allows to build 3D digital models that can be analysed and managed in a virtual environment and can be relocated, assembled or restored in order to suggest or graphically support archaeologists’ interpretations and reconstructions. The paper shows the methodology developed for the virtual restoration of the statue of Nero starting from the 3D digitization of the torso that was found 500 years ago by the Roman theatre of Bologna, Italy, the ancient Bononia.

The Building Information Modelling (BIM) software enables the users to communicate and design, understand appearance, performance and cost in the spatial and urban design process. Another important use of the BIM technology is the documentation and 3D reconstruction of cultural heritage monuments. The appropriate BIM software equips the users with tools to easily capture and analyse concepts and maintain the coordination of design data through documentation and 3D modelling. Many developments come up in the BIM field and software industry for design, construction-reconstruction, restoration and management of the cultural heritage 3D models, using BIM tools; mainly commercial as well as free or open source. Nevertheless, recently the growing popularity of open source has altered the landscape in software industry, as they attract many users. This paper presents a review of some recent research on the topic. We review the recent developments focusing on the OSS that can be used at various stages of BIM process in the digital documentation of cultural heritage. The results show that there is more preference in the commercial software due to the fact that the OSS is not yet complete and covers all stages of the BIM process. However, lately we have the Edificius in architectural BIM design and “BIM Vision” as Industry Foundation Classes (IFC) model viewer that try to attract as many users as possible. These tools are free and they could well be used for the digital reconstruction of cultural heritage.

With the diffusion of Virtual Archaeology, many projects in the field of Cultural Heritage attempt to virtually reconstruct historical buildings of different types. Unfortunately, some of these 3D reconstructions still have as principal aim to impress the external users, while the correct interpretation of the buildings modeled is much more important in the domain of archaeological research. Still more critical is the situation when we have to encounter a reconstruction of a monument which is not visible anymore, or which consists only of few architectural remains. The main purpose of this paper is to introduce an innovative methodology to verify hypothetical scenarios of 3D architectural reconstructions, specifically for ancient theatres. In very recent time 3D visibility analysis applied to archaeological context using ArcGIS has been developed, in particular about social-urban studies. In this paper, visibility analysis in 3D contexts is used as an additional instrument to correctly reconstruct architectural elements of the large Roman theatre of Gortyn, in Crete. The results indicate that the level of visibility of the stage, and consequently of the presumed actors, from some of the more representative sectors of the cavea, is of crucial importance for leading to a right reconstruction model of the theatre.

[EN] Can we preserve cultural heritage and, consequently, the memory of the past? To answer this question, one should look at the digital revolution that the world has gone through in recent decades and analyse the complex and the dialectical relationship between cultural heritage and new technologies. Thanks to these, increasingly accurate reconstructions of archaeological sites and historical monuments are possible. The resulting digital replicas are fundamental to experience and understand cultural heritage in innovative ways: they have complex and dynamic relationships with the original objects. This research paper highlights the importance and the scientific validity of digital replicas aimed at understanding, enhancing and protecting cultural heritage. The study focuses on the virtual reconstruction of the constructive phases, from the mid-15th century to date, of one of the most emblematic Gothic-Renaissance buildings in the city of Milan (Italy): the convent of Santa Maria delle Grazie, famous worldwide for hosting Leonardo da Vinci's Last Supper painting. This site proved to be an ideal case study because of its troubled and little-known history that led to numerous changes over the centuries. Thanks to a methodological approach based on the analysis of the documentary sources and three-dimensional (3D) modelling, it was possible to outline the chronological succession of the convent transformations; the way in which these overlapped the pre-existing structures was described starting from the Renaissance harmonious and organic interventions, to finally reach 18th -19th centuries inhomogeneous and incompatible additions. Finally, the research was completed by mapping the 3D models based on the sources used and their different levels of accuracy. The 3D models have thus become a valid tool for checking and verifying the reconstruction hypotheses., [ES] ¿Podemos preservar el patrimonio cultural y, por consiguiente, la memoria del pasado? Para responder a esta pregunta, es necesario examinar la revolución digital que ha experimentado el mundo en las últimas décadas y analizar la compleja relación dialéctica entre el patrimonio cultural y las nuevas tecnologías. Gracias a estas, son posibles reconstrucciones precisas de los sitios arqueológicos y de los monumentos históricos. Las réplicas digitales son fundamentales para experimentar el patrimonio cultural de forma innovadora; de ellas destaca también que juegan un papel importante en la comprensión del patrimonio cultural, y que poseen complejas y dinámicas relaciones con los objetos originales. Este artículo de investigación destaca la importancia y la validez científica de las réplicas digitales destinadas a comprender, mejorar y proteger el patrimonio cultural. El estudio se centró en la reconstrucción virtual de las fases constructivas, desde mediados del siglo XV hasta la actualidad, de uno de los edificios gótico-renacentistas más emblemáticos de la ciudad de Milán (Italia): el convento de Santa María de las Gracias, famoso en todo el mundo por ser la sede de la pintura mural de la Última Cena de Leonardo da Vinci. Este sitio demostró ser un caso de estudio ideal debido a su problemática y poco conocida historia que llevó a numerosos cambios a lo largo de los siglos. Gracias a un enfoque metodológico basado en el análisis de las fuentes documentales y en la modelización tridimensional (3D), fue posible esbozar la sucesión cronológica de las transformaciones; se trabajó desde las intervenciones armoniosas y orgánicas del renacimiento, hasta alcanzar las adiciones desiguales e incompatibles de los siglos XVIII y XIX. Por último, la investigación se completó con el mapeado de los modelos 3D sobre la base de las fuentes utilizadas y sus diferentes niveles de precisión. Los modelos 3D se han convertido así en un instrumento válido para comprobar y verificar las hipótesis reconstructivas.

Traditional written historical investigation and analysis have from the beginning consisted of a sometimes unstable mixture of fact and conjecture, hard evidence and inspired imagination. To encourage 3-D modelling of cultural heritage artefacts to be taken seriously as historical scholarship this inevitable and ambiguous balance can be highlighted and to a significant degree documented and modulated by London Charter principles. This enhances the scholarly integrity of these models as examples of serious research based historical investigation, and helps avoid the dangers of inflated or unverified “media hype” which can compromise or discredit such work .

[EN] The research presented here puts together different direct and/or physical operations all aimed to enhance the knowledge and produce advanced dissemination of the very last ship from the “Mosquitos’ Fleet” which operated during the World War I and in some operations even during the World War II. The exploration of the valuable remains along the Thames River in London, the intervention with archaeology strategy, the use of digital survey procedures, the investigation of the references about the fleet, the digital modelling and drawing and the final online sharing of the 3D model, brought together to a specific digital heritage creation of an element with a high risk of getting lost. An international team worked together on the poor shipwreck of the Eothen (the last name assigned to this ship by its last owner). The intervention was operated in very odd operative conditions, with the hull invaded by the mud, the very wet environment and the daily flood of the area, such a mix of difficult conditions were a special challenge for the survey operations, which were optimized and accurately planned to allow the best and efficient result in terms of coverage and level of details. The following post-processing aimed to the production of a classic set of 2D drawings and an interactive 3D model, accessible in a real-time visualization from the sketchfab.com platform creates an excellent base for a possible following restoration/musealisation intervention, or, at least, allow digital preservation of a rich dataset of the remains of this interesting piece from the naval history of the first half of the 20th century., [ES] La investigación que aquí se muestra reúne diferentes operaciones directas y/o físicas, todas orientadas a mejorar el conocimiento y producir una puesta en valor del último barco de la “Flota de Mosquitos” que operó durante la Primera Guerra Mundial y en algunas operaciones incluso durante la Segunda Guerra Mundial. Presentamos la exploración de los valiosos restos a lo largo del río Támesis en Londres, la intervención con estrategia arqueológica, el uso de procedimientos de levantamiento digital, la investigación de las referencias sobre la embarcación, el modelado y dibujo digital, y el intercambio final en línea del modelo 3D, reunidos en una aportación de patrimonio digital específico de un elemento con alto riesgo de perderse. Un equipo internacional , trabajaron juntos en el naufragio del Eothen (nombre asignado a este barco por su último propietario). La toma de datos se realizó en condiciones operativas muy complejas, con el casco invadido por el limo del rio, el entorno muy húmedo y la inundación diaria de la zona; esta mezcla de condiciones difíciles fueron un desafío especial para llevar a cabo las operaciones de levantamiento, las cuales fueron optimizadas con el objetivo de obtener el mejor y más eficiente resultado en términos de cobertura y nivel de detalle. El siguiente posprocesamiento estuvo dirigido a la obtención de un conjunto clásico de dibujos 2D, así como de un modelo 3D interactivo, accesible en una visualización en tiempo real desde la plataforma Sketchfab.com. Así se ha creado una base excelente para una posible intervención posterior de restauración/musealización, o, al menos, para obtener la preservación digital de un rico conjunto de datos de los restos de esta interesante pieza de la historia naval, de la primera mitad del siglo XX.

In ancient Rome, damnatio memoriae was a practice of erasing the memory of condemned persons from historical records after their death. This practice was usually addressed by the Senate to Roman elites and emperors who were declared enemies of the State, in order to preserve the honour of Rome. This condemnation usually included practices such as, for example, the erasure of names sculpted on inscriptions and the destruction or reworking of statues and of any other image of the person. Emperor Nero, for example, was condemned to this practice immediately after his death and a wide iconographic repertoire on him was therefore destroyed or deeply damaged. This lack of information can actually be improved thanks to the possibilities of virtual restoration and reconstruction offered by 3D digital technologies.The aim of this paper is to show how the possibility to acquire 3D reality-based data from archaeological finds allows to build 3D digital models that can be analysed and managed in a virtual environment and can be relocated, assembled or restored in order to suggest or graphically support archaeologists’ interpretations and reconstructions. The paper shows the methodology developed for the virtual restoration of the statue of Nero starting from the 3D digitization of the torso that was found 500 years ago by the Roman theatre of Bologna, Italy, the ancient Bononia.

[EN] The Portes Mordelaises, remnants of the medieval city walls of Rennes, France, has been the subject of several archaeological excavations until 2017. From these excavations, we created a three-dimensional (3D) model of the site reconstructed as it would have appeared during the 15th century, including the surrounding plus the interiors of its famed towers. Once our efforts and results were officially recognised as being of national interest by the French Ministry of Culture and Communication, Department of Heritage and the National Museum Service of France, we presented our virtual model reconstruction in an exhibition curated by the Museum of Bretagne, entitled "Rennes, les vies d'une ville" (Rennes, the Lives of a City). This approach to 3D reconstruction of the site served to further study Rennes’ origins, its construction, organisation, as well as its historic relationship to surrounding territories.

[EN] 3D reconstructions for research and conservation of archaeological sites and objects are becoming increasingly common as laser and photogrammetric techniques are now more readily accessible to nonspecialists. Most of these imaging techniques have been applied to sites and/or objects that can be physically visited, handled, measured and studied in various ways. However, little or no attention has been paid to the potential of modern 3D modelling techniques for obtaining new quantitative and qualitative information from sites and objects which have been destroyed or are no longer accessible. This paper explores the potential of Structure from Motion (SfM) to provide fresh insight into the scientific exploitation of ancient image archives. Two case studies from Western France will be used to illustrate this: a series of photographs of one decorated orthostate from the Neolithic gallery grave of Kermorvan (Le Conquet, Finistère), dating from 1911-12, and a 12-minute video of the excavation of a Bronze Age mound in Kervingar (Ploudalmézeau, Finistère), dating from 1953., [ES] La modelización tridimensional dirigida a la investigación y conservación de objetos y yacimientos arqueológicos ha ido cobrando una importancia progresiva, a medida que las técnicas láser y fotogramétricas se han generalizado y simplificado. La gran mayoría de estas técnicas ha sido por el momento aplicada a elementos que pueden ser hoy en día visitados, manejados, medidos y estudiados de diferentes formas. Sin embargo, poca o ninguna atención se ha prestado desde nuestra disciplina al potencial de estos métodos de reconstrucción tridimensional para obtener nuevos datos cuantitativos y cualitativos de elementos destruidos o actualmente inaccesibles. En esta línea, el presente trabajo explora el potencial de la técnica Structure from Motion (SfM) para la explotación científica de archivos de imágenes antiguos. Para ilustrar esta aproximación presentamos aquí dos casos de estudio: la modelización de un ortostato decorado del dolmen de Kermorvan (Le Conquet, Finistère, Francia) a partir de una serie fotográfica de 1911-1912; la modelización de varios elementos de la excavación del túmulo de la Edad del Bronce de Kervingar (Ploudalmézeau, Finistère, Francia), a partir de un video de 12 minutos realizado en 1953., This research has been carried out within the framework of the ICARE (Iconographie et Collections d’Anthropologie de Rennes, UMR 6566 CReAAH) and eSCOPES (Evolving spaces: coastal landscapes of the Neolithic in the European Lands Ends; Marie Curie-IEF 2013-2015) projects.

[EN] Extended Abstract:We present a methodological approach for the representation, visualisation and analysis of three-dimensional (3D) models of meaningful details in stone reliefs provided by digital documentation tools and subsequent processing. For this aim, anthropomorphous shapes engraved on a flat stone slab found in Sierra de Fontcalent (Alicante) are studied. The object under consideration was located near two archaeological sites, Cova del Fum–a cave with presence of the Chalcolithic material (López, 2010)–and the archaeological site of Fontcalent, with remains from different phases of occupation spanning from 7th-6thBC to the 20thcentury (Ximénez, 2012).In the last few years, the use of digital tools provided by new technologies and software development has left traditional work methodology behind (De Reu et al., 2014)while enabling the development of new approaches to both minimise heritage alteration and provide objective and accurate information (Lopez-Menchero, Marchante, Vincent, Cárdenas, & Onrubia, 2017). 3D documentation allows recording of cultural heritage at a reasonable cost with precision and quality through digital photography and SfM (Structure from Motion) photogrammetry with specialised software (De Reu et al., 2013).In this project, recording and documentation with digital photography and automated photogrammetric techniques are applied to the Fontcalent stone slab for its digitisation and subsequent 3D representation. From the resulting model, a two-folded line of study is obtained. On the one hand, a Digital Elevation Model (DEM) is generated to study the microtopographies of the stone with geographic analysis techniques provided by Geographic Information Systems (GIS) from different lighting conditions and surface reflections, which are calculated by hillshading or LRM (Local Relief Model) for the interpretation of the object (Carrero-Pazos, Vilas, Romaní, & Rodríguez, 2014;Gawior, Rutkiewicz, Malik & Wistuba, 2017).On the other hand, from both the 3D model and the point cloud, the study is completed with the application of the methods of analysis and visualisation based on the Morphological Residue Model (MRM) which stands out every single detail of the surface morphology of the object (Caninas, Pires, Henriques, & Chambino, 2016;Correia, Pires, & Sousa, 2014). Further visualisations are based on Reflectance Transformation Imaging (RTI) which provides different shadows and reflections over the object from the application of a multidirectional illumination (Happa et al., 2010; Malzbender, Gelb, Wolters, & Zuckerman, 2000; Mudge et al., 2010).The results thus obtained of the Fontcalent stone slab allow us to visualise several characteristic elements. The anthropomorphous figure awaking interest is also combined with the figure resulting from different visualisations applied with GIS techniques which may resemble a zoomorph. The use of visualisation techniques shown in this study has been fundamental in order to recognise the latter element. The composition reveals a zigzag line already appreciated before the study so that it is interesting to check if visualisations based on GIS techniques are able to highlight it though being shallow incisions. In our experience regarding this study, visualisation by using the hillshading technique shows a greater level of 3D detail than that provided by the application of the sky-view factor technique which offers a flattering view. However, the former technique may occasionally show shadows which hide other details, unlike the latter technique which plots the entire slab surface illuminated while differentiating the associated microtopography on the basis of its marks. The use of shaders in combination with hillshading and particularly combined with high pass filtering, contributes to improving the visualisation and accuracy of shadowed areas. As a result, we conclude that the results obtained in this work by lighting techniques with GIS add a greater level of detail in comparison to those provided by the mesh or the point cloud.The study of the Fontcalent stone slab paves the way for two working hypotheses to be developed: on the one hand, its anthropological origin possibly related to the Chalcolithic, and on the other hand, its study as natural geological formations with ichnofossils.The digitisation of cultural heritage with available 3D technologies should be a mandatory requirement when facing any study, analysis or intervention. With the current development of such techniques, we have verified their contribution to fundamental characteristics in the corresponding stages of visualisation and study. Thus, the proposed methodology is presented as an accurate and complete alternative for the study and analysis of the existing cultural heritage, and opens new ways for the revision, reinterpretation and revaluation of the previously evaluated heritage through traditional techniques., [ES] Este trabajo tiene por objetivo presentar una aproximación metodológica para la representación, visualización y análisis de modelos tridimensiones (3D) de relieves y detalles significativos sobre piedra a partir de la aplicación de herramientas de documentación digital y su correspondiente procesado. Para ello se toma como objeto de estudio unas figuras antropomorfas que aparecen sobre una piedra caliza en forma de lasca plana y de espesor contante hallada en la Sierra de Fontcalent (Alicante). Sobre ella se aplican a una escala de objeto, técnicas de documentación y registro con fotogrametría mediante fotografía digital y técnicas SfM (Structure from Motion) para su digitalización y posterior representación en 3D. Del modelo resultante se genera un MDE (Modelo Digital de Elevación) para estudiar las microtopografías de la pieza, a través de visualizaciones topográficas obtenidas mediante herramientas de análisis geográfico que nos proporcionan los programas SIG (Sistemas de Información Geográfica) a partir de distintas condiciones de iluminación y reflejo de las superficies que proporcionan técnicas como el sombreado (hillshading) o el LRM (Local Relief Model) y que posibilitan la interpretación arqueológica del objeto bajo estudio. El estudio se completa mediante la aplicación de los métodos de análisis y visualización basados en el Modelo de Residuo Morfológico (MRM) y de RTI (Reflectance Transformation Imaging), respectivamente, generados ambos mediante el software Cloudcompare. De este modo, la metodología propuesta se presenta como una alternativa precisa y completa para el estudio y análisis del patrimonio cultural existente, y abre nuevas vías para la revisión, reinterpretación y revalorización del patrimonio evaluado con anterioridad mediante técnicas tradicionales.

[EN] With the rise of available computing capabilities, structural analysis has recently become a key tool for building assessment usually managed by art historians, curators, and other specialist related to the study and preservation of ancient buildings. On the other hand, the flourishing field of procedural modeling has provided some exciting breakthroughs for the recreation of lost buildings and urban structures. However, there is a surprising lack of literature to enable the production of procedural-based buildings taking into account structural analysis, which has proven to be a crucial element for the recreation of faithful masonry structures. In order to perform an in-depth study of the advances in this type of analysis for cultural heritage buildings, we performed a study focused on procedural modeling that make use of structural analysis methods, especially in its application to historic masonry buildings such as churches and cathedrals. Moreover, with the aim of improving the knowledge about structural analysis of procedurally-recreated historical buildings, we have taken a geometric structure, added a set of procedural walls structured in masonry bricks, and studied its behavior in a generic, freely-available simulation tool, thus showing the feasibility of its analysis with non-specialized tools. This not only has allowed us to understand and learn how the different parameter values of a masonry structure can affect the results of the simulation, but also has proven that this kind of simulations can be easily integrated in an off-the-shelf procedural modeling tool, enabling this kind of analysis for a wide variety of historical studies, or restoration and preservation actions., [ES] Con el creciente aumento de las capacidades computacionales, el análisis estructural se ha convertido en una herramienta clave para la evaluación del estudio y conservación de edificios antiguos por parte de los historiadores del arte, curadores y otros especialistas. Por otro lado, el floreciente campo del modelado procedural ha proporcionado avances interesantes para la reconstrucción de edificios y estructuras urbanas no accesibles. Sin embargo, hay una sorprendente falta de métodos que permiten la generación deedificios procedurales, teniendo en cuenta el análisis estructural, los cuales handemostrado ser un elemento crucial para la concepciónde estructuras de mampostería. Con el fin de realizar un estudio en profundidad de los avances en este tipo de análisis para edificios del patrimonio cultural, se realizó un estudio centrado en elroldelmodelado proceduralque realizanmétodos de análisis estructural, especialmente en su aplicación a los edificios históricos de albañilería, tales como iglesias y catedrales. Por otra parte, con el objetivo de mejorar el conocimiento sobre el análisis estructural de los edificios históricos concebidosproceduralmente, hemos tomado una estructura geométrica de un atrículo, añadidoun conjunto de paredesproceduralesestructuradasen ladrillos, y estudiado su comportamiento conuna herramienta de simulación de pública disponibilidad.Con esto sedemuestra la viabilidad de su análisis con herramientas no especializadas. Esto no sólo nos ha permitido entender y aprender cómo los diferentes valores de los parámetros de una estructura de mampostería pueden afectar los resultados de la simulación, sino tambiénque este tipo de simulaciones se puede integrar fácilmente en una herramienta de modelado proceduralal alcance de todo público, lo que permite acercar este tipo de análisis a una amplia variedad de estudios históricos o acciones de restauración y conservación., This work was partially funded by the TIN2014-52211-C2-2-R project from Ministerio de Economia y Competividad, Spain.

[EN] With the diffusion of Virtual Archaeology, many projects in the field of Cultural Heritage attempt to virtually reconstruct historical buildings of different types. Unfortunately, some of these 3D reconstructions still have as principal aim to impress the external users, while the correct interpretation of the buildings modeled is much more important in the domain of archaeological research. Still more critical is the situation when we have to encounter a reconstruction of a monument which is not visible anymore, or which consists only of few architectural remains. The main purpose of this paper is to introduce an innovative methodology to verify hypothetical scenarios of 3D architectural reconstructions, specifically for ancient theatres. In very recent time 3D visibility analysis applied to archaeological context using ArcGIS has been developed, in particular about social-urban studies. In this paper, visibility analysis in 3D contexts is used as an additional instrument to correctly reconstruct architectural elements of the large Roman theatre of Gortyn, in Crete. The results indicate that the level of visibility of the stage, and consequently of the presumed actors, from some of the more representative sectors of the cavea, is of crucial importance for leading to a right reconstruction model of the theatre., [ES] Con la difusión de la arqueología virtual, muchos proyectos en el campo del patrimonio cultural intentan reconstruir edificios históricos de varios tipos. Desafortunadamente, algunas de estas reconstrucciones 3D tienen todavíacomo principal objetivoimpresionar al/a la usuario/a, cuando la correcta interpretaciónde los monumentos modelados es mucho más importante en el campo de la arqueología. La situación es aún más crucial cuando tenemos que reconstruir algo que ya no es visible, o de lo que hay solo unos pocos restos. Por esta razón, el principal propósito de este artículo es presentar una metodología innovadora para verificar escenarios hipotéticos de reconstruccionesarquitectónicasen 3D, específicamente deteatros antiguos. Recientemente, el análisis de la visibilidad en 3D utilizando ArcGis ha sido aplicado al contexto arqueológico, en particular a estudios socio-urbanos. En este artículo, elanálisis de la visibilidad en contextos 3D se usa como un instrumento adicional que reconstruyecorrectamente elementos arquitectónicos del gran teatro Romano de Gortina, en Creta. Los resultados muestranqueel nivel de visibilidad de la plataforma, y consiguientemente de los supuestos actores, desde algunos de los sectores más representativos de la cavea,es de crucial importancia para conseguir la reconstrucción del modelo más correcto del teatro., This research was supported by the Greek State Scholarship Foundation (I.K.Y.) under the grant for post graduated study of foreign students in Greece. The presentation of this paper has been possible thanks to the funding of the Institute for Mediterranean Studies in Rethymno, Crete. I would like to thank Dr. Apostolos Sarris for his helpful suggestions both during my research and about this paper.
