A streaming framework for seamless detailed photo blending on massive point clouds
Pintus R., Gobbetti E., Callieri M.
We present an efficient scalable streaming technique for mapping highly detailed color information on extremely dense point clouds. Our method does not require meshing or extensive processing of the input model, works on a coarsely spatially-reordered point stream and can adaptively refine point cloud geometry on the basis of image content. Seamless multi-band image blending is obtained by using GPU accelerated screen-space operators, which solve point set visibility, compute a per-pixel view-dependent weight and ensure a smooth weighting function over each input image. The proposed approach works independently on each image in a memory coherent manner, and can be easily extended to include further image quality estimators. The effectiveness of the method is demonstrated on a series of massive real-world point datasets.Source: Eurographics 2011: the 32nd annual conference of the European Association for Computer Graphics, EG 2011, pp. 25–32, Llandudno, UK, 11-15 aprile 2011

Claudian Aqueduct in Rome, from the 3D survey to the virtual reconstruction according to archaeological records
Vecchione A., Callieri M.
This paper presents a possible way to manage a virtual reconstruction of the Roman aqueduct Aqua Claudia in Rome, in particular, the section between Tor Fiscale and Porta Furba. The aqueduct is a peculiar monument, because it spans multiple scales: it has an architectural scale, as a building, but also a landscape scale, as a part of the local geography, and also a detail scale, considering each section as a single entity, with traces and carachteristics worth to be investigated. Furthermore, the modern urban illegal development and the fragmentary conservation status of the aqueduct due to a wide middle-age mining phase, resulted in the monument being split in several chunks, each one, now, an object on its own. These considerations had a great influence on the methodology and on the data recording technique we had to choose: a classical total station survey was paired with a photogrammetric campaign, to cope with the different scales of the monument to be documented. For the second step, that is the organization and visualization of the collected data, we chose to work with 3DHOP (3D Heritage Online Presenter), an open-source software package for the creation of interactive Web presentations of high-resolution 3D models. Using this tool, we have built a "3D hub" that, at different scales, can link together the 3D geoemtry, the data from the ground surveys and the classical archaeological records, providing a more immediate and structured access to the available information. Thus, we have split the visualization into two differents layer: the first one, at a landscape scale, let us to have a complete view of the section; the second layer is focused on the single chunks of the monument, especially on their structure, to better understand the ancient building techniques and its evolution in time. The surveyed data will be also enriched with a modeling of the original shape of the aqueduct, and of its modifications.Source: CHNT 2017 - Cultural Heritage and New Technologies, 22nd edition, pp. 89–90, Vienna, Austria, 08- 10 November 2017

Using and combining remote-sensing technologies to document the Castillo de Consuegra in Castilla-La Mancha, Spain
Lureau A., Maschner H., Lopez-Menchero Bendicho V. M., Du Vernay J., Mcleod J., Matthew V., Callieri M.
The Castillo de La Muela in Consuegra, Castilla-La Mancha, Spain, is a medieval castle that has a long history starting from the Xth century. It is now one of the most well preserved castles of the region and it has undergone a lot of restoration campaigns. A lot of questions are still not answered about this castle: it's the state of preservation and the various restoration campaigns need to be assessed and documented, the castle needs to be presented with new technics to the public in order to attract new visitors, and the surroundings of the castle and its lost outer surrounding walls have yet to be entirely found and documented. In order to answer as many questions as possible, the castle was surveyed with remote-sensing technics by the CVAST from USF, Tampa, in collaboration with the Universities of Castilla-La Mancha and the Université Paris1 Panthéon-Sorbonne. The team used a lot of remote-sensing technologies to survey the castle and its surroundings: terrestrial laser scanning was used to document the exterior and interior of the castle; aerial photogrammetry by drone was used to document the upper parts of the castle and the whole hill on which it sits; terrestrial photogrammetry was used to document the inner parts of the castle, and 360 panoramas were made in order to create a virtual tour for the visitors. This survey will be included in a larger campaign using other remote-sensing technologies such as geophysics and aerial surveys using thermal imaging, but also well-known methods such as GIS and cartography will complete the new documentation in order to present all the new data to the public and contemplate an excavation campaign. Relevance conference / Relevance session: The survey campaign is about documenting Cultural Heritage in a remote area of Spain with new technologies, and how combining those to obtain the best of each would provide the best documentation. Innovation: Remote-sensing has been used before to document medieval structures, but rarely on a building this size and possibly never to that extent of precision and completion that the three surveys provided.

A 3D digital approach for the study and presentation of the Bisarcio site
Derudas P., Sgarella M. C., Callieri M.
Recently, 3D-from-photos and close-range photogrammetry have established themselves as important modern technologies in archaeology. Nevertheless, three-dimensional survey has not reached its full potential in the daily work of excavation, as it has been generally restricted to exceptional and monumental cases. The digging of the late- and post-medieval cemetery of Bisarcio, Sardinia, was an opportunity to experiment with 3D survey. After an extensive 3D survey, covering the entire excavation area and duration, 3D models have been used for the documentation and interpretation of the stratigraphy, and, to create a web-based visualization and dissemination tool. The three interconnected steps, of documentation, interpretation, and visualization and dissemination, were used to evaluate the effectiveness of the 3D data in each step, and also to build a complete 3D workflow. The results are promising: with the correct protocol, these procedures may be soon part of the archaeologist's daily routines.Source: CAA2016 44th Conference on Computer Applications and Quantitative Methods in Archaeology., pp. 389–398, Oslo, 30 marzo - 3 aprile 2016

Fast low-memory seamless photo blending on massive point clouds using a streaming framework
Pintus R., Gobbetti E., Callieri M.
We present an efficient scalable streaming technique for mapping highly detailed color information on extremely dense point clouds. Our method does not require meshing or extensive processing of the input model, works on a coarsely spatially reordered point stream, and can adaptively refine point cloud geometry on the basis of image content. Seamless multiband image blending is obtained by using GPU-accelerated screen-space operators, which solve point set visibility, compute a per-pixel view-dependent weight, and ensure a smooth weighting function over each input image. The proposed approach works independently on each image in a memory-coherent manner, and can be easily extended to include further image-quality estimators. The effectiveness of the method is demonstrated on a series of massive real-world point datasets. © 2011 ACM.Source: ACM journal on computing and cultural heritage (Print) 4 (2011). doi:10.1145/2037820.2037823

3D archaeological data management via web: The experience with 3DHOP software
Vecchione A., Lureau A., Callieri M.
3D Heritage Online Presenter (3DHOP) is a framework for advanced web-based visual presentations of high-resolution 3D content. Developed at the Visual Computing Lab CNR ISTI, 3DHOP was designed to cope with the specific needs of cultural heritage projects, supporting web-based publishing of very high-resolution digitized results and enabling the documentation of complex restoration actions. The present paper highlights, through some case studies (Peltuinum archaeological area, AQ, and Castillo de La Muela in Consuegra), the potentials of 3DHOP's tools for the management of data from both active (laser scanner) and passive sensors (photogrammetry and aerophotogrammetry). In addition, problems and solutions encountered during the organization and personalization of web pages will be presented. The goal of this operation is to create a three-dimensional hub that can collect and link traditional archaeological documentation to 3D geometry.Source: Archeologia e calcolatori 30 (2019): 483–486. doi:10.19282/ac.30.2019.35

Sharing archaeological knowledge: the interactive reporting system
Derudas P., Dell'Unto N., Callieri M., Apel J.
This study describes the development of a digital reporting system designed to provide archaeologists with a dynamic and interactive 3D web platform that can be used for describing in great detail records and activities undertaken across a multi-year field investigation campaign. The system was used to compose the archaeological report of a multi-year investigation and employed during the pandemic crisis for supporting digital courses in archaeological practice; the paper also reports the preliminary results of the use of this platform within teaching activities. Unlike other web solutions, this system supports an assisted publication of archaeological contents that integrates a 3D visualization system in the reporting process, exploiting the communicative potentials of 3D models and the web. This study represents a contribution to research on sustainable forms of management and publication of archaeological contents and their reuse and sharing.Source: Journal of field archaeology (2021). doi:10.1080/00934690.2021.1911132

Dynamic collections: a 3D web infrastructure for artifact engagement
Ekengren F., Callieri M., Dininno D., Berggren A., Macheridis S., Dell'Unto N.
Archaeological collections are crucial in heritage studies and are used every day for training archaeologists and cultural heritage specialists. The recent developments in 3D acquisition and visualization technology has contributed to the rapid emergence of a large number of 3D collections, whose production is often justified as the democratization of data and knowledge production. Despite the fact that several 3D datasets are now available online, it is not always clear how the data - once stored - may be engaged by archaeology students, and the possible challenges the students may face in the learning process. The goal of the Dynamic Collections project at Lund University is to develop a novel 3D web infrastructure designed to support higher education and research in archaeology. At the onset of the COVID-19 pandemic in the spring of 2020, all teaching at Lund University moved online, reinforcing the urgency for such an infrastructure. By letting a group of students test an early version of the system as part of their online teaching, we were able to study how they used and interacted with an archaeological collection in 3D and explore the intersection of digital methods and pedagogy in archaeology. This article presents the preliminary results from this experiment.Source: open archaeology 7 (2021): 337–352. doi:10.1515/opar-2020-0139

Néroulidis A., Pouyet T., Tournon S., Rousset M., Callieri M., Manuel A., Abergel V., Malavergne O., Cao I., Roussel R., Granier X., Rodier X., De Luca L.
This article explores the design, development and deployment of a digital platform for scholarly work at Notre Dame Cathedral and demonstrates the transformative impact of digital technology on heritage disciplines. By merging technology and human expertise, the platform facilitates the creation, integration, sharing, and analysis of extensive scientific data on the multidisciplinary post-fire study of the cathedral. This multi-layered approach includes community building for collaborative efforts, digital tools tailored to different stakeholders, data structuring approaches for managing multidimensional features, and experience-based workflows for documenting, categorising and semantically enriching scientific and restoration data. The overall goal is to introduce an integrated solution for collaborative studies and to promote a digital memory of the collective initiative in accordance with the principles of FAIR for scientific heritage data. This initiative not only supports the research and restoration of Notre Dame, but also serves as a paradigm for future conservation and documentation efforts in the field of cultural heritage.Source: Journal of cultural heritage (2023). doi:10.1016/j.culher.2023.09.016

A realtime immersive application with realistic lighting: the Parthenon
Callieri M., Debevec P., Pair J., Scopigno R.
Off-line rendering techniques have nowadays reached an astonishing level of realism but pay the cost of long computational times. The new generation of programmable graphic hardware, on the other hand, gives the possibility to implement in realtime some of the visual e ects previously available only for cinematographic production. We describe the design and implementation of an interactive system which is able to reproduce in realtime one of the crucial sequences from the short movie 'The Parthenon' presented at Siggraph 2004. The application is designed to run on a specific immersive reality system, making possible for a user to perceive the virtual environment with nearly-cinematographic visual quality.Source: Computers & graphics 30 (2006): 368–376. doi:10.1016/j.cag.2006.02.015

Off-line rendering techniques have nowadays reached an astonishing level of realism but pay the cost of long computational times. The new generation of programmable graphic hardware, on the other hand, gives the possibility to implement in realtime some of the visual effects previously available only for cinematographic production. We describe the design of an interactive system which is able to reproduce in realtime one of the crucial sequences from the short movie 'The Parthenon' presented at Siggraph 2004. The application is designed to run on a specific immersive reality system, making possible for a user to perceive the virtual environment with a nearly cinematographic visual quality. In this paper we present the principal ideas of the project, discussing the design issues and the technical solutions used to implement the realtime demo.Source: SPIE International Symposium on Optical Metrology, Munich, 13-17 June 2005

CENOBIUM Cultural Electronic Network Online: Binding Up Interoperably Usable Multimedia
Baracchini C., Callieri M., Corsini M., Dellepiane M., Dercks U., Keultjes D., Montani C., Scognamiglio M., Scopigno R., Sigismondi R., Wolf G.
CENOBIUM project is a multimedia presentation of Romanesque cloister capitals from the Mediterranean region. High-resolution digital photographs, 3-D models, and panoramas will virtually link the capitals to their original surroundings, thus representing them within their original architectural and conceptual contexts. The cloister of Monreale is the starting point of this project, which combines classical and innovative methods of Art History with the latest in multimedia data technology. The paper describes the different acquisition and documentation; it also outlines the main components of the system which will allow the user to virtually explore the cloister.Source: Electronic Imaging & the Visual Arts.

Digital reconstruction and visualization in archaeology. Case-study drawn from the work of the Swedish Pompeii Project
Dell'Unto N., Ferdani D., Leander A., Dellepiane M., Callieri M., Lindgren S.
The Swedish Pompeii Project started in 2000 as a research and fieldwork activity initiated by the Swedish Institute in Rome. The aim was to record and analyze an entire Pompeian city-block, Insula V 1. Since autumn 2011 a new branch of advanced digital archaeology, involving 3D reconstructions and documentation methods, was added to the project agenda. The insula was completely digitized using laser scanner technology and the raw data were employed to develop different research activities in the area of digital visualization. This paper presents the recent results of the 3D interpretation of the house of Caecilius Iucundus. This research activity was developed employing a large variety of historical and archaeological sources such as: archaeological reports, historical image documentation (printed as well as in edited material) and analysis of the in situ structures. This work was characterized by the experimentation of a new workflow of data development, where the elaboration of the interpreted structures took place directly in virtual space, using the scanned model as geometrical reference. This method easily connected all the historical and archaeological sources collected for the interpretation, opening a new discussion about different possible interpretation of the house. Moreover, a Cave Automatic Virtual Environment (CAVE) was used in different occasions as platform where the different hypotheses could be discussed in the context given by the actual state of the archaeological structures. The use of an accurate and resolute replica of the site as a backdrop for the virtual reconstruction allowed a high level of control on the proposed hypotheses during the interpretation process. This study enabled the acquisition of new and important information about the house, thus, bringing a significant contribution to the archaeological analysis of Insula V 1, suggested as pilot project for wider use.Source: Digital Heritage - 2013 Digital Heritage International Congress, pp. 621–628, Marseille, France, 27 October - 1 November 2013

Pompei revived: scanning Mission - Insula V 1
Dell'Unto N., Dellepiane M., Callieri M., Leander A., Lindgren S., Larsson C.
The Swedish Pompeii Project started in 2000 as a fieldwork initiated from the Swedish Institute in Rome. The aim was to record and analyze a full Pompeian city-block, Insula V 1. This paper presents the initial results of one of the actions in the context of this project. In October 2011, two houses were acquired using 3D scanning and 3d-from-photos techniques, and the data was processed to obtain an accurate and complete model. Through the use of Virtual Reality Techniques, it will be possible to visit the Pompeian houses of Casa del Torello and Casa di Cecilio Giocondo understanding the relation between the actual archaeological context and their original outfit. The collected data will be used also to design and test a web-based access system, where the entire dataset will be available for browsing, measurement and data extraction. The features of HTML5, in particular WebGL, will be used to deliver realtime 3D content and interaction.Source: Archaeology in the Digital Era, edited by Graeme Earl, Tim Sly, Angeliki Chrysanthi, Patricia Murrieta-Flores, Constantinos Papadopoulos, Iza Romanowska, David Wheatley, pp. 199–207.

Web-based visualization for 3D data in archaeology: The ADS 3D viewer
Galeazzi F., Callieri M., Dellepiane M., Charno M., Richards J., Scopigno R.
The solid geometry of archaeological deposits is fundamental to the interpretation of their chronological sequence. However, such stratigraphic sequences are generally viewed as static two-dimensional diagrammatic representations which are difficult to manipulate or to relate to real layers. The ADS 3D Viewer is a web-based resource for the management and analysis of archaeological data. The viewer was developed to take advantage of recent developments in web technology, namely the adoption of WebGL (Web Graphics Library) by current web browsers. The ADS 3D Viewer combines the potential of the 3D Heritage Online Presenter (3DHOP), a software package for the web-based visualization of 3D geometries, with the infrastructure of the Archaeology Data Service (ADS) repository, in the attempt to create a platform for the visualization and analysis of 3D data archived by the ADS.Two versions of the viewer have been developed to answer the needs of different users. The first version, the Object Level 3D Viewer, was implemented to extend the browsing capability of ADS project archives by enabling the visualization of single 3D models. The second version, the Stratigraphy 3D Viewer, is an extension which allows the exploration of a specific kind of aggregated data: the multiple layers of an archaeological stratigraphic sequence. This allows those unable to participate directly in the fieldwork to access, analyse and re-interpret the archaeological context remotely. This has the potential to transform the discipline, allowing inter-disciplinary, cross-border and 'at-distance' collaborative workflows, and enabling easier access to and analysis of archaeological data.Source: Journal of Archaeological Science: Reports (Print) 9 (2016): 1–11. doi:10.1016/j.jasrep.2016.06.045
