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 TECHNICAL REPORT SERIES, pp. 25-32. Llandudno, UK, 11-15 aprile 2011

Intuitive representation of surface properties of biomolecules using BioBlender
Andrei R M, Callieri M, Zini Mf, Loni T, Maraziti G, Pan Mc, Zoppè M
Background: In living cells, proteins are in continuous motion and interaction with the surrounding medium and/ or other proteins and ligands. These interactions are mediated by protein features such as electrostatic and lipophilic potentials. The availability of protein structures enables the study of their surfaces and surface characteristics, based on atomic contribution. Traditionally, these properties are calculated by physico-chemical programs and visualized as range of colors that vary according to the tool used and imposes the necessity of a legend to decrypt it. The use of color to encode both characteristics makes the simultaneous visualization almost impossible, requiring these features to be visualized in different images. In this work, we describe a novel and intuitive code for the simultaneous visualization of these properties. Methods: Recent advances in 3D animation and rendering software have not yet been exploited for the representation of biomolecules in an intuitive, animated form. For our purpose we use Blender, an open-source, free, cross-platform application used professionally for 3D work. On the basis Blender, we developed BioBlender, dedicated to biological work: elaboration of protein motion with simultaneous visualization of their chemical and physical features. Electrostatic and lipophilic potentials are calculated using physico-chemical software and scripts, organized and accessed through BioBlender interface. Results: A new visual code is introduced for molecular lipophilic potential: a range of optical features going from smooth-shiny for hydrophobic regions to rough-dull for hydrophilic ones. Electrostatic potential is represented as animated line particles that flow along field lines, proportional to the total charge of the protein. Conclusions: Our system permits visualization of molecular features and, in the case of moving proteins, their continuous perception, calculated for each conformation during motion. Using real world tactile/sight feelings, the nanoscale world of proteins becomes more understandable, familiar to our everyday life, making it easier to introduce "un-seen" phenomena (concepts) such as hydropathy or charges. Moreover, this representation contributes to gain insight into molecular functions by drawing viewer's attention to the most active regions of the protein. The program, available for Windows, Linux and MacOS, can be downloaded freely from the dedicated website http://www.bioblender.euSource: BMC BIOINFORMATICS, vol. 13

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.

Using and combining remote-sensing technologies to document the Castillo de Consuegra in Castilla-La Mancha, Spain
Lureau A, Maschner H, Lopezmenchero Bendicho Vm, 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 Mc, 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.

Fast low-memory seamless photo blending on massive point clouds using a streaming framework

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.

Different paradigms for different spaces: showing the Montagnola Tomb inside & out.
Callieri M, Manganelli Del Fà R, Arrighetti A, Minutoli G, Pancani G
The "Montagnola Tomb" is an Aetruscan burial mound in Sesto Fiorentino. Excavated in 1959, has never been properly opened to the public. Given the difficulty of having a full-time opening, the institutions wanted a "virtual" presentation of the hypogeum, to integrate the future visits. But which was the correct way to present such a monument? As most buildings, this tomb, too, spans across two different spaces: an outer space and an inner space. The mound is made to be seen from outside, as a monumental statement of power, and inside, as a private place of contact with the departed. Wanting to give to the visitor a complete perception of the monument, we had to work on both of these aspects, choosing for each side the correct presentation paradigm. For the outer space, the user should appreciate the shape, size and proportions of the structure, and understand the relationship between visible and invisible areas. Maquettes have been always used in museums, to present environments and reconstructions of ancient spaces. Their language is cross-cultural and accessible. By combining the language of maquettes with digital technologies, it was possible to setup an interactive presentation of the tomb structure using predefined views, cut-through sections, and transparency effects. Conversely, for the inner space, the user has to experience a sense of presence inside the mound. The paradigms of Virtual reality and immersive 3D are the perfect tools to let the viewer roam inside the tomb, and experience the inner space with an assisted navigation. We chose the web3D platform, as it ensured a wider audience, and the 3DHOP tool to implement the two viewers. We are now moving "outwards", extending the two presentation paradigms: using 3D printing to create physical maquettes, while, on the other side, porting the 3D virtual visit on immersive VR devices. Relevance for the conference: This work is focused on the design of methodologies for the effective data presentation to the public through advanced technologies Relevance for the session: The paper deal exactly with the issue of presentation paradigms, going from the physical to the immersive VR Innovation: We show how, with a careful design, iti si possible to create two specialized viewers with significantly diverse presentation paradigms, starting from the same base data and tools, and then expanding the concept to physical reproduction and VR

Digital models for publishing of research project data The case of Villa Corsi Salviati Guicciardini in Sesto Fiorentino
Callieri M, Cantisani E, Casciani A, Cuzman Oa, Manganelli Del Fa R, Riminesi C, Rosa P, Tiano P, Vettori S
Creating a digital model of an object allows us to get an accurate "copy" of it, both in shape and colour. The online interactive visualization of these models is a powerful dissemination tool that allows us to visualize the object in all its parts and to easily communicate the methodologies used and the results obtained in scientific projects and research. For the project "La Conservazione programmata dei Beni Culturali lapidei in giardini storici. Progetto di ricerca e definizione di protocolli", the models of case studies, normally not visible because they are in private ownership, can be viewed on-line and include information about the project and the methodologies used for characterization Conservation status and monitoring of conservative treatments.Source: KERMES, vol. 107 (issue luglio-settembre), pp. 87-91

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, vol. 30, pp. 483-486

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

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, vol. 7 (issue 1), pp. 337-352

This article presents the preliminary results from this experiment.Source: OPEN ARCHAEOLOGY, vol. 7 (issue 1), pp. 337-352

The Dynamic Collections project: providing structured online access to digital replicas
Berggren Å, Callieri M, Dell'Unto N, Derudas P, Dininno D, Ekengren F, Naponiello G
This contribution will present the latest results of the Dynamic Collections project, highlighting the evolution of the approach, methodologies and tools. The core idea behind the project was to explore the possibilities of working online, for teaching and study purposes, with high-resolution digital replicas of archaeological artefacts, going beyond the single-object approach. To this aim, the project built an archive of high-resolution digital models, and designed and implemented an online platform that makes it possible to build, annotate and share a custom assemblage of the objects in the archive (a Dynamic Collection, that is). These annotated collections can be the pivot element in the definition of collaborative workflows and shared research/teaching environments.

The dynamic collections - a 3D web platform of archaeological artefacts designed for data reuse and deep interaction
Callieri M, Berggren Å, Dell'Unto N, Derudas P, Dininno D, Ekengren F, Naponiello G
The Dynamic Collections project is an ongoing initiative pursued by the Visual Computing Lab ISTI-CNR in Italy and the Lund University Digital Archaeology Laboratory-DARKLab, Sweden. The aim of this project is to explore the possibilities offered by a deep, structured interaction with a large set of digital replicas of archaeological artefacts. The project developed and deployed a web-based platform containing a large number of digital artefacts, and a set of dedicated tools to interact with them at a both artefact- and collection-level. This platform has been used in university courses and research activities with positive feedback from the community. In this contribution, we want to describe various aspects of the management of the project, its evolution, and discuss the roadmap of future developments and research directions.

A digital platform for the centralization and long-term preservation of multidisciplinary scientific data belonging to the Notre Dame de Paris scientific action
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, vol. 65 (issue January–February 2024), pp. 210-220

Laser Scanning of a complex cave system during multiple campaigns: a case study of the Domica Cave, Slovakia
Ján Kaňuk, Jozef Šupinský, John Meneely, Zdenko Hochmuth, Ján Šašak, Michal Gallay, Marco Callieri
Caves are natural sub-surface hollows with an extremely complex three-dimensional (3D) morphology. The inherent mystery and natural beauty captivate human curiosity; therefore, the caves have become the subject of tourism but also research and protection. From a scientific point of view, the caves are a source of essential information about the past environment important for understanding contemporary conditions and changes of the environment. Generating highly detailed and accurate digital twins of caves provides means for improving their cartographic representation and use of geospatial analytical methods to study the cave surface. Terrestrial laser scanning (TLS) has been demonstrated in the last decade to be the most suitable technology for such a task. Despite higher costs, TLS as an active technique overcomes the challenge of underground darkness in comparison with traditional tacheometry or digital cameras and lights needed for photogrammetry. This chapter demonstrates how TLS can be used in 3D mapping of a complex show cave, which is a part of 27,000 m long system of underground corridors formed inside a limestone plateau that spans the border between Slovakia and Hungary in Central Europe. The multifold TLS campaigns resulted in scanning over 5,000 m of corridors and experience in the scanning of various kinds of cave passages in diverse environmental circumstances. The acquired data improved the standard cave cartography, enabled research of cave ceilings and walls inaccessible in person, helped the cave management, and resulted in new interactive visualisations easily accessible via the Internet.

Is Kelami's method still useful in the smartphone era? The virtual 3-dimensional reconstruction of penile curvature in patients with peyronie's disease: a pilot study
Pavone C, Abrate A, Altomare S, Vella M, Serretta V, Simonato A, Callieri M
Background: Peyronie's disease is an idiopathic fibrotic disease affecting the penile tunica albuginea. Among other resulting deformities, the more common penile curvature should be assessed preferentially with in-office goniometric estimation after pharmacologically induced erection, although clearly invasive and uncomfortable. Aim: In the present pilot study, we investigated the usefulness for the patient and the surgeon of a 3-dimensional (3D) reconstruction of the penile curvature obtained through photogrammetry software in clinical evaluation and surgical planning. Methods: Enrolled patients received alprostadil 10 ?g by intracavernous injection. Then, the medical personnel took a sequence of up to 50 photographs in orthostatism via a smartphone and processed them to obtain a 3D model of the whole groin area with 3DF Zephyr free software (3Dflow SRL, Verona, Italy), to take measurements of the penile curvature with MeshLab software (National Research Council of Italy, Rome, Italy) and to simulate the results after corporoplasty with Blender software (Blender Foundation, Amsterdam, the Netherlands). Finally, we submitted a 1-5 Likert scale to patients and surgeons investigating their satisfaction with the use of the 3D model during preoperative counseling, surgical planning, and the esthetic results after surgery. Outcomes: We investigated the patient and surgeon satisfaction with the use of the 3D model in understanding/evaluating the pathology and the surgical planning during the preoperative visit and the satisfaction with the final esthetic results in relation to the preoperative model itself. Results: 4 patients were included. The median photographs acquisition and computer processing time were 39 seconds and 347.5 minutes, respectively. All the patients and surgeons involved gave a score of >=4 to all the items investigated. Clinical implications: The 3D model of the penile curvature is very useful both to the patient and the surgeon to understand the severity of the disease and the possible surgical management. Strength & Limitations: This is a pilot study including only 4 cases, but it is the first experience in which the patients with Peyronie's disease had the possibility to see a virtual 3D model of their penile curvature and final esthetic results after corporoplasty, based on 3 freely available computer applications. Conclusion: Our pilot study has shown that it is possible to quickly obtain a sequence of photographs to create an accurate virtual 3D model of the penis of patients with Peyronie's disease, helping the patients and the surgeon during preoperative counseling and surgical planning.

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, vol. 30 (issue 3), pp. 368-376
