Designing and developing interactive kiosks for cultural heritage: best practices and common issues
Potenziani M., Callieri M., Cignoni P.
Interactive kiosks are a smart way to engage museum visitors and complement their visiting experience with another layer of engagement and interaction with the artworks. Kiosks are also a perfect complement to an integrated Cultural Heritage project that applies digital technologies for the study, the documentation, and the conservation of works of art, as it might help in adding a new dimension of dissemination and public outreach to the project. The design and development of an interactive kiosk for Cultural Heritage involves very different knowledge, skills, and tools. However, it is possible to find various software components that can be used, with a reasonable effort and a sound strategy, to set up an interactive kiosk able to display complex 2D+ and 3D data and implement advanced interaction paradigms. The aim of this work is to help possible developers, by discussing some working strategies and approaches, highlighting possible tools, and analyzing past activities of kiosk development and deployment.Source: SPRINGER SERIES ON CULTURAL COMPUTING, pp. 473-497

3D imaging application to the study of the early Neolithic ceramic complex: the decorated pottery of Rio Tana (Abruzzi, Italy)
Petrinelli Pannocchia C., Vassanelli A., Terranova A., Potenziani M., Pingi P., Callieri M., Cignoni P.
This study aims to demonstrate the potential of 3D analysis in the study of prehistoric ceramic complexes. Due to the production systems used, prehistoric pottery decorations can vary significantly. Examining the frequency of various decorative methods used at different sites may help identify areas potentially connected to specific traditional elements. However, this is usually a cumbersome and time-consuming task. 3D digital methodologies can bring several advantages in the interpretation of ceramic decoration, providing newtools that can improve analytical skills, speed up the decision process, and support the researcher’s conclusions. This work focuses on the application of these methodologies to the study of decorated ceramics from the Neolithic site of Rio Tana (Abruzzo, central Italy): firstly, a pottery complex from this site has been 3D digitised; then, an interactive and web-based 3D visualisation system has been developed to enable access and study of these digital data. By comparing archaeological data with experimental data, in parallel with the analysis of 3D models’ surfaces, it has been possible to better define the technique employed and quickly identify the type of tool used to create the ceramic decorations. Furthermore, the web-based system made it possible to share and disseminate the digital dataset with the community, creating the conditions to make it easier to compare the frequency of different decoration methods and tools used at Rio Tana with other sites.Source: THE EUROPEAN PHYSICAL JOURNAL PLUS, vol. 139 (issue 6)

ARIADNEplus Visual Media Service 3D configurator: toward full guided publication of high-resolution 3D data
Potenziani M., Ponchio F., Callieri M., Cignoni P.
The use of digital visual media in everyday work is nowadays a common practice in many different domains, including Cultural Heritage (CH). Because of that, the presence of digital datasets in CH archives and repositories is becoming more and more relevant. However, the correct management of these assets, specialized and often complex, it is not always trivial, especially for communities of users lacking specific training. In these cases, systems enabling assisted data management during the different phases of their life cycle, can be a solution. The Visual Media Service (VMS) is a web-based platform that enables the easy publication of complex visual media assets, specifically targeting the CH domain. It allows users to upload high-resolution images, RTI (Reflectance Transformation Imaging) images, and 3D models, transforming them into an efficient format for interactive web visualization. The VMS is an end-to-end solution able to support the entire publishing process, from data uploading to presentation customization. To expand its adoption in the CH community, the ARIADNEplus project aimed to enhance its features, providing innovative services for archaeological data publication. This paper introduces the VMS 3D configurator, a new tool designed to improve the visual organization of 3D archaeological datasets in the VMS. The configurator guides content creators through a multi-step wizard, offering customization options for the presentation of 3D models. The configurator consists of five different configuration stages, each providing specific customization features, such as model orientation, appearance, scene navigation, viewer interface, and annotation of points of interest. In addition to provide a detailed description of all the configuration possibilities, the paper will also discuss uses, limitations, and potential developments of the 3D configurator, and of the entire platform too, highlighting the value of the VMS as a tool for publishing, exploring, and disseminating CH data.DOI: 10.5281/zenodo.8075050

Cultural Heritage 3D data on the Web: issues and perspectives
Potenziani M, Ponchio F, Callieri M, Cignoni P, Scopigno R
Les modèles numériques 3D sont unanimement considérés comme un atout inestimable pour l'étude, la gestion et la promotion du patrimoine culturel. L'urgence de COVID-19 a accéléré la tendance commune à travailler à distance et, pour le patrimoine culturel, la présentation, le partage et l'accès aux données 3D en ligne sont désormais perçus comme une nécessité. Malheureusement, l'absence de méthodologies, d'outils et d'infrastructures standard rend difficile le passage du stockage local à la gestion en ligne de données 3D complexes. Dans cette contribution, nous souhaitons évaluer l'état de l'art de l'utilisation avancée de la 3D sur le web, en soulignant les besoins actuels, en présentant quelques études de cas et en explorant les perspectives futures.

ARIADNEplus D15.2 - Final report on ARIADNEplus services
Marberg Jf, Bardi A, Vlachidis A, Meghini C, Binding C, Tudhope D, Sinibaldi F, Ponchio F, Mangiacrapa F, Radmanlivaja I, Callieri M, Potenziani M, Lamé M, Assante M, Pagano P, Hermon S, Vassallo V
This deliverable describes the activities carried out within Work Package 15 (WP15) of the ARIADNEplus project by the different partners and describes the results achieved. The work package consists of several individual tasks and subtasks with the overall goal to develop and provide useful services to archaeologists. This means the work package is by nature heterogeneous with stand-alone tasks and services. Efforts have been made to facilitate collaboration between the individual tasks through joint work package meetings. This has resulted in new cross-task contacts being made, and some sharing of expertise to improve services has been done. A service design template aligning the ARIADNEplus services with the requirements from European Open Science Cloud (EOSC) has been created. In connection with this, the ARIADNEplus AO-CAT ontology has been adapted to the requirements from EOSC Resource Data Model (Task 15.1). The Visual Media Service (Task 15.2.1) has had a new format added, allowing for 2D visualisation of LIDAR data in DEM format. In addition, three other standards have been added: gITF, ThreeJS and IIIF, supporting various functionality in the service. The service has also been adapted to support integration with the ARIADNEplus infrastructure in D4Science. A visual wizard has been defined to guide Visual Media Service users to add hotspots to a 3D scene easily and quickly. This extension, initially implemented in 3DHOP will allow archaeologists to create interactive links from the digital 3D model to the related documentation without writing any source code (Task 15.2.2). Task 15.2.3 reworked the Online 3D Database System for Endangered architectural and archaeological Heritage in the south Eastern MEditerRAnea area (EpHEMERA). EpHEMERA is a service provided by the Cyprus Institute to visualize in 3D archaeological excavations, ancient buildings, and their related documentation. In EpHEMERA, it is possible to visualise, online and through standard web browsers, 3D architectural and archaeological models (classified according to a specific type of risk), query the database system and retrieve metadata attached to each digital object, and extract geometric and morphological information about the Cultural Heritage asset. The visualisation and annotation tool of the TSS project have been ported to the OpenLime library and integrated into the Visual Media Service (Task 15.2.1). An additional layer of SVG annotations have been developed and added to the service. The Annotation service have been used and improved in three different pilot projects. (Task 15.3.2) Various strands of work have been done improving services for text mining and Natural Language Processing (Task 15.4). One of these efforts has been building upon the outcomes of the preceding ARIADNE project. A set of archaeological Named Entity Recognition NLP pipelines were reconfigured and deployed for easier use on the General Architecture for Text Engineering (GATE) cloud. Another effort has been on extracting temporal archaeological information using two different parallel approaches, normalisation and named entity recognition. A Python development platform has been used to unify the various services. A Vocabulary Annotation Tool (Task 15.3.1) was developed using the same platform, as part of Task 15.4. The tool facilitates the locating and tagging of vocabulary terms within free text and outputs suggested subject annotations in a range of formats. The GeoPortal service (Task 15.5) is a new REST service designed to manage complex spatio-temporal documents defined by metadata profiles. It was released as a component of the gCube framework. A prototype using the service was deployed and operated to manage archaeological excavation projects (Task 15.7). Two services for querying the RDF AO-Cat metadata records aggregated by the ARIADNEplus Infrastructure was established (Task 15.6): a full-text index service and a SPARQL endpoint. The full- text index service is based on OpenSearch and supports the needed query functionality of the ARIADNEplus portal. The SPARQL endpoint allows performance of semantic queries on the RDF records within the ARIADNEplus data and knowledge cloud.Project(s): ARIADNEplus

ARIADNEplus D11.1 - Quantity of Access Offered - TA4
Bassett S, Potenziani M
This deliverable describes the Trans National Access (TNA) activities carried out during the ARIADNEplus project within Work Package 11 (WP11) by CNR and describes the results achieved by this work package. CNR were responsible for the delivery of TNA entitled "Visual Media for the Documentation of Fieldwork and Artefacts" at their premises in Pisa, Italy. The first TNA call went out in 2019 and only three person were able to complete their in-house training before the pandemic restrictions stopped travel. No further activities could be undertaken until 2021 when it was decided to organise the TNA as four Summer Schools and all previously accepted applicants were offered (and took up) places on the week-long courses. All candidates had to send in application forms describing their projects and how these would benefit from the use of Visual Media. One of three independent reviewers each evaluated the applications and awarded a mark and recommendation to ensure the quality and relevance of the training for the applicants. The WP11 training was designed to support researchers who wish to use visual media for the management of activities in the field and/or for the study of objects for their specific project. Participants had access to equipment and facilities in the CNR-ISTI (VCL) laboratory with technical support from the tutors, which provided the opportunity to work with state-of-the-art cameras and scanners, post-processing packages and advanced viewing platforms. Each student had the possibility to learn about creating visual media datasets for the documentation of artefacts and archaeological finds, taking in account preservation and sharing of datasets, guidance and advice were tailored to each individual project. The training concluded with a review of the results achieved and further input from local experts on continuation of the work once back home. In total, all six applicants were offered places of which five were able to attend (one dropped out due to a serious family situation). Each student was asked to complete feedback forms after completing their TNA placements. The quality of the students and their projects as well as the training provided is reflected in the feedback. All the students were highly appreciative of the Summer School and what they had learned and from the comments, it is apparent that the Summer School catered very well to the individual requirements of each student. In terms of numbers, the attendance was lower than expected (six offers for 10 places) and if the Summer School had been able to run a year or two earlier as well, it is highly likely that the target would have been met. However, it is evident that the TNA was very well received, meeting the expectations and requirements of the students so that the lower numbers actually was a benefit for those who were able to attend.Project(s): ARIADNEplus

Leafing through the painting "Ecce Homo" by Antonello da Messina: multimodal imaging techniques and data-fusion
Cucci C., Potenziani M., Albertin F., Ruberto C., Picollo M., Stefani L., Callieri M., Siotto E., Pingi P., Scopigno R., Castelli L., Taccetti F., Bettuzzi M., Brancaccio R., Morigi M. P., De Vita F.
European Research Infrastructures for Heritage Science enable access to cutting-edge technologies and top-level expertise to solve specific queries on high value artworks and heritage assets. A successful example of this approach was the ECCEHOMO Project, carried out within E-RIHS program [1-3] and dedicated to non-invasive multimodal analysis of the painting “Ecce Homo” by Antonello da Messina (ca. 1430–1479). This masterpiece of the Early Italian Renaissance is carefully preserved at the Collegio Alberoni in Piacenza (Italy). Being extremely fragile, this painting needs continuous monitoring and the implementation of careful preventive conservation strategy, which should be based on sound knowledge of materials and conservation status of the painting. The interdisciplinary research undertaken in the project combined cutting-edge 3D and 2D techniques to perform a systematic, rigorously non-invasive, analysis of the artwork. By exploiting the complementarity of imaging spectroscopic techniques operating in different regions of the electromagnetic spectrum (from X-rays to the Ultraviolet, Visible and Infrared ranges) the painting was fully investigated, virtually ‘leafing through' its levels and structures the from the surface to the wooden support. Structured-light 3D metrological survey was used to digitize the external surface of the artwork. The surface irregularities and the support were analyzed with a structured-light 3D scanner and X-ray tomography. UV fluorescence was used to visualize the aged layers of varnishes. X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI) were combined to study pictorial materials and their distributions, and the artist technique. Hidden details were brought to the light, like a fingerprints traces. Data-fusion from the 2D and 3D techniques provided new insights on the artwork and updated documentation of the conservation status. The obtained digital documentation was exploited to compile web-based interactive platforms targeted at the visualization and dissemination of the results, for both professional users and large public.

Virtual clones for cultural heritage applications
Potenziani M, Banterle F, Callieri M, Dellepiane M, Ponchio F, Scopigno R
Digital technologies are now mature for producing high quality digital replicas of Cultural Heritage (CH) artifacts. The research results produced in the last decade have shown an impressive evolution and consolidation of the technologies for acquiring high-quality digital 3D models, encompassing both geometry and color (or, better, surface reflectance properties). Some recent technologies for constructing 3D models enriched by a high-quality encoding of the color attribute will be presented. The focus of this paper is to show and discuss practical solutions, which could be deployed without requiring the installation of a specific or sophisticated acquisition lab setup. In the second part of this paper, we focus on new solutions for the interactive visualization of complex models, adequate for modern communication channels such as the web and the mobile platforms. Together with the algorithms and approaches, we show also some practical examples where high-quality 3D models have been used in CH research, restoration and conservation.

"Ecce Homo" by Antonello da Messina, from non-invasive investigations to data fusion and dissemination
Albertin F., Ruberto C., Cucci C., Callieri M., Potenziani M., Siotto E., Pingi P., Scopigno R., Bettuzzi M., Brancaccio R., Morigi M. P., Castelli L., Taccetti F., Picollo M., Stefani L., De Vita F.
Scientific investigations of artworks are crucial in terms of preservation since they provide a measurable evaluation of the materials and the state of conservation. This is the case of Antonello da Messina's painting "Ecce Homo": its delicate state of conservation, with the need for constant monitoring, required a broad and in-depth diagnostic campaign to support the restorers. The project was carried out entirely in situ using non-invasive cutting-edge techniques and proposes a multimodal and data-centric approach, integrating 3D and 2D methodologies. The surface irregularities and the support were analysed with a structured-light 3D scanner and X-ray tomography. The painting materials were investigated with X-ray fluorescence scanning (MA-XRF) and reflectance hyperspectral imaging (HSI). Primarily, the data were jointly used for a scientific scope and provided new knowledge of the painting in terms of materials and painting techniques. In addition, two web-based interactive platforms were developed: one to provide restorers and experts with a new perspective of the hidden geometries of the painting, and the other targeted at the general public for dissemination purposes. The results of the Ecce Homo scientific analysis were exhibited, using a touch-screen interface, and developed for different user levels, from adults to kids.Source: SCIENTIFIC REPORTS, vol. 11 (issue 1), pp. 15868-15885

ARIADNEplus D15.1 - Mid-term interim report on ARIADNEplus services
Marberg Jf, Bardi A, Meghini C, Binding C, Tudhope D, Sinibaldi F, Ponchio F, Mangiacrapa F, Radmanlivaja I, Potenziani M, Lamé M, Assante M, Pagano P, Hermon S, Vassallo V
This deliverable describes the activities carried out during the first half of the ARIADNEplus project within Work Package 15 (WP15) by the different partners and describes the results achieved thus far. The work package consists of several individual tasks and subtasks with the overall goal to develop and provide useful services to archaeologists. This means that the work package in itself is by nature heterogeneous with stand-alone tasks and services. Efforts have been made to facilitate collaboration between the individual tasks through joint work package meetings. This has resulted in new cross-task contacts being made, and some sharing of expertise to improve services has been done. A service design template aligning the ARIADNEplus services with the requirements from the European Open Science Cloud (EOSC) has been created. In connection to this, the ARIADNEplus AOCAT ontology has been adapted to the requirements from the EOSC Resource Data Model. The Visual Media Service (Task 15.2.1) has had a new format added, allowing for 2D visualization of LIDAR data in DEM format. In addition, three other standards have been added: gITF, ThreeJS and IIF, supporting various functionalities in the service. The service has also been adapted to support integration with the ARIADNEplus infrastructure in D4Science. A visual wizard has been defined to guide Visual Media Service users to add hotspots to a 3D scene easily and quickly. This extension, initially implemented in 3DHOP, will allow archaeologists to create interactive links from the digital 3D model to the related documentation without writing any source code (Task 15.2.2). To integrate the EpHEMERA service (Task 15.2.3) into the ARIADNEplus infrastructure environment, a revision of the service is needed. As this revision needs to be based upon user needs and comments, tutorials have been created and a user survey has been prepared, distributed, and analysed. Revision of the service and implementation of new components have started. A prototype of an image annotation service has been created based on the OpenAnnotation format, which is intended to be integrated with the Visual Media Service. The first prototype supports vector annotation of relightable images. The GeoPortal service (Task 15.5) is a new REST service designed to manage complex space-temporal documents defined by metadata Profiles. It has been released as a component of the gCube framework. A prototype using the service has been deployed and operated to manage archaeological excavation projects (Task 15.7). Two services for querying the RDF AO-Cat metadata records aggregated by the ARIADNEplus Aggregative Infrastructure has been established (Task 15.6): a full-text index service and a SPARQL endpoint. The full-text index service is based on Elasticsearch and supports the needed query functionality of the ARIADNEplus portal. The SPARQL endpoint allows to perform semantic queries on the RDF records in the ARIADNEplus data and knowledge cloud.Project(s): ARIADNEplus

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

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

The EcceHomo project
Callieri M, Pingi P, Potenziani M, Siotto E, Scopigno R
In the 2017 "Access Programme" call of the E-RIHS.it (European Research Infrastructure for Heritage Science) project, which makes the diagnostic tools and the technologies of a number of research institutes available to Italian conservation institutions, the project concerning the Ecce Homo by Antonello da Messina from the Collegio Alberoni di Piacenza collection was selected. The objective of the non-invasive diagnostic investigations carried out by CNR-ISTI (Pisa), CNR-IFAC (Florence), INFN-CHNet (Bologna) and INFN-CHNet (Florence), was to achieve greater knowledge of the work and create an objective digital support for evaluation and measurement that could assist the activities of conservators and restorers. The joint work of the multidisciplinary team of the Italian node of E-RIHS.it generated a three-dimensional graphic representation, digital twin of the painting, which varies over time and can be useful as a basis for comparison in the periodic control of the Ecce Homo of Piacenza. All the data gathered with the scientific investigations were integrated (by the Visual Computing Laboratory of the CNR-ISTI of Pisa), through their mapping on the 3D/2D space of the digital representation of the work, in a multimedia platform, with the aim of make possible easy consultation and visualization of all data on the web, both for scientific and educational purposes. The multimedia platform was presented as a kiosk in a public conference dedicated to the "ECCEHOMO" project, which had excellent feedback from the public. The kiosk was subsequently integrated into the museum visit itinerary of the Alberoni College of Piacenza. Developed with HTML/JavaScript technology, the kiosk is based on the HTML5 WebGL API, which makes 2D/3D rendering possible without plug-ins on all major web browsers. The use of web technologies allows installation on a stand-alone machine (as in the museum installation) but at the same time publication on the web. The web visualization of high resolution images is managed by the Relight library, developed by ISTI-CNR. The generation of multiresolution 3D models, and their web visualization, is managed by the Nexus, SpiderGL, and 3DHOP software, all developed by the Visual Computing Laboratory of the CNR-ISTI in Pisa. The contents of the kiosk were designed, discussed and validated with the collaboration of all the work teams involved in the project (CNR-ISTI, CNR-IFAC, INFN-CHNet Bologna and Florence) and by Francesca De Vita, restorer and conservator of the artwork.

Developing and maintaining a web 3D viewer for the CH community: an evaluation of the 3DHOP framework
Potenziani M, Callieri M, Scopigno R
3DHOP (3D Heritage On-line Presenter) has been released 4 years ago, as an open-source framework for the creation of interactive visualization of 3D content on the web, aimed at the CH field. Transforming a research tool into a software "product" usable by the heterogeneous CH community is not a simple task and requires a significant amount of resources plus a specific design. This work presents the evolution of the 3DHOP system, and the complex relationship with its community of users, made of content creators, CH experts and general public. We will discuss the new features introduced, as well as the design and implementation strategy employed to maintain the software and make it usable by developers. We will evaluate the effectiveness of the platform by illustrating some of the applications built with 3DHOP either internally or by external users, as well as by presenting the results of a survey aimed at gathering the opinions and suggestions of the user community.

Publishing and consuming 3D content on the Web. A survey
Potenziani M, Callieri M, Dellepiane M, Scopigno R
Three-dimensional content is becoming an important component of the World Wide Web environment. From the advent of WebGL to the present, a wide number of solutions have been developed (including libraries, middleware, and applications), encouraging the establishment of 3D data as online media of practical use. The fast development of 3D technologies and related web-based resources makes it difficult to identify and properly understand the current trends and open issues. Starting from these premises, this survey analyzes the state of the art of 3D web publishing, reviews the possibilities provided by the major current approaches, proposes a categorization of the features supported by existing solutions, and cross-maps these with the requirements of a few main application domains. The results of this analysis should help in defining the technical characteristics needed to build efficient and effective 3D data presentation, taking into account the application contexts.Source: FOUNDATIONS AND TRENDS IN COMPUTER GRAPHICS AND VISION, vol. 10 (issue 4), pp. 244-333

The results of this analysis should help in defining the technical characteristics needed to build efficient and effective 3D data presentation, taking into account the application contexts.Source: FOUNDATIONS AND TRENDS IN COMPUTER GRAPHICS AND VISION, vol. 10 (issue 4), pp. 244-333

Exploring Effective Publishing in the Web3D World
Potenziani M
Web3D is most certainly an intriguing world. Its story has changed suddenly with the advent of WebGL, evolving from a slow and stagnant past to a dynamic and rapidly-evolving present. 3D data is becoming one of the key digital media on the Web, with a wide number of solutions specifically designed for publishing and consuming three-dimensional content online. Unfortunately, this field experimented a quick and often chaotic growth, presenting nowadays a dichotomy between pure research-oriented and market-oriented approaches. This has somehow shaped the directions of Web3D development, creating de-facto standards and solutions tailored to specific fields, or only focused towards mainstream publishing actions and thus unable to cope with the needs of more specialized and technical 3D users. Under these premises, the aim of the thesis has been to investigate the shortcomings and missing features of Web3D technology, as well as to propose a solution aimed at filling these empty spots. We start by presenting an analysis of the state of the art of 3D Web publishing, surveying the features provided by the major current approaches, useful to categorize the existing solutions and to cross-map them with the requirements of the different application domains. Then, in what is the main contribution of the thesis, we exploit the result of our analysis of the Web3D and discuss the design and implementation of a flexible platform, aimed at providing an effective framework for the Web presentation of specialized 3D content. Our solution is tailored to cope with the needs of a challenging application context, Cultural Heritage. Therefore it exploits highly-efficient solutions for data transfer and rendering, intuitive interaction/manipulation paradigms, and features enabling trans-media elements connections. To validate the proposed framework, the thesis presents the results of two specific interactive visualization applications, addressing different Web3D presentation needs: a first one aimed at a museum dissemination initiative, and a second one developed to support scientific analysis. Finally, we also tested the capabilities of our platform for the implementation of service-oriented applications: a project aimed at providing a service for the easy publication of complex, technical media types; and a more structured scenario of multimedia Digital Libraries, proposing a pipeline useful to rationalize and speed-up the publication of heterogeneous 3D dataset on a multimedia repository.
