3DHOP: a novel technological solution for the development of online virtual museums
Potenziani M., Callieri M., Scopigno R.
The interactive visualization of 3D content on the Web has gained momentum in recent years, thanks to the release of ad-hoc technology as part of HTML5. However, so far, few products fully exploit this opportunity for the easy and quick embedding of high-resolution 3D models in a Web page. 3DHOP (3D Heritage Online Presenter) is an advanced solution for easy publishing of 3D content on the Web.Source: ERCIM news online edition 97 (2014): 52–53.

3D Heritage online presenter
Callieri M., Potenziani M., Dellepiane M., Corsini M., Ponchio F., Scopigno R.
3D Heritage Online Presenter (3DHOP) is a framework for the creation of advanced web-based visual presentations of high-resolution 3D content. 3DHOP has been designed to cope with the specific needs of the Cultural Heritage (CH) field. By using multiresolution encoding, it is able to efficiently stream high-resolution 3D models (such as the sampled models usually employed in CH applications); it provides a series of ready-to-use templates and examples tailored for the presentation of CH artifacts; it interconnects the 3D visualization with the rest of the webpage DOM, making it possible to create integrated presentations schemes (3D + multimedia). Thanks to its modular nature and a declarative-like setup, it is easy to learn, configure, and customize at different levels, depending on the programming skills of the user. This allows people with different background to always obtain the required power and flexibility from the framework. 3DHOP is written in JavaScript and it is based on the SpiderGL library, which employs the WebGL subset of HTML5, implementing plugin-free 3D rendering on many web browsers.Project(s): ARIADNE

ARIADNE visual media service: easy Web publishing of advanced visual media
Ponchio F., Potenziani M., Dellepiane M., Callieri M., Scopigno R.
This paper describes the design and development of a service for 'visual media' files. In the first phase of the ARIADNE project we reviewed the status of visual media resources (2D, RTI, 3D) in the archaeology domain, but there was possibility of publishing visual media resources on the web. To fill this gap we have designed a service aimed at providing easy and unsupervised publication on the web. The service provides a very easy interface (a simple web form) that allows the user to upload the visual media file; the data is then transformed in a web-compliant format, supporting multi-resolution encoding, compression, and progressive transmission. At the end of the data-processing phase the user receives an email containing the URL of the published asset (or, in case he/she wants to store the file locally, a .zip file). Specific browsers for the three types of media have also been developed, based on 3DHOP technology.Source: CAA 2015 - 43rd Annual Conference on Computer Applications and Quantitative Methods in Archaeology, pp. 433–442, Siena, Italy, 31 March - 2 April 2015

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.Source: 16th Eurographics Workshop on Graphics and Cultural Heritage, Vien, Austria, 12-15 November 2018

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 10 (2018): 244–333. doi:10.1561/0600000083

Delivering and using 3D models on the web: are we ready?
Scopigno R., Callieri M., Dellepiane M., Ponchio F., Potenziani M.
Digital technologies are now mature for producing high quality digital replicas of Cultural Heritage (CH) assets. The research results produced in the last decade ignited an impressive evolution and consolidation of the technologies for acquiring high-quality digital three-dimensional (3D) models, encompassing both geometry and color. What remains still an open problem is how to deliver those data and related knowledge to our society. The web is nowadays the main channel for the dissemination of knowledge. Emerging commercial solutions for web-publishing of 3D data are consolidating and becoming a de-facto standard for many applications (e-commerce, industrial products, education, etc.). In this framework, CH is a very specific domain, requiring highly flexible solutions. Some recent experiences are presented, aimed at providing a support to the archival of archaeological 3D data, supporting web-based publishing of very high-resolution digitization results and finally enabling the documentation of complex restoration actions. All those examples have been recently implemented on the open-source 3D Heritage Online Presenter (3DHOP) platform, developed at CNR-ISTI.Source: Virtual archaeology review 8 (2017): 1–9. doi:10.4995/var.2017.6405

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.

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.Source: From Pen to Pixel - Studies of the Roman Forum and the Digital Future of World Heritage, edited by Fortini Patrizia, Krusche Krupali, pp. 225–233.

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.Source: Heritage for the Future, Science for Heritage: A European Adventure for Research and Innovation, pp. 378–383, Paris, France, 15-16/03/2022

Visual Media Service
Ponchio F., Callieri M., Potenziani M., Dellepiane M., Scopigno R.
The Visual Media Service provides easy publication and presentation on the web of complex visual media assets (3D, RTI, High Resolution 2D Images). It is an automatic service that allows to upload visual media files on an server and to transform them into an efficient web format, making them ready for web-based visualization. The Visual Media Service is an end-to-end solution able to support the entire publishing process, from data uploading to presentation customization. The service provides a very easy interface (a simple web form) that allows the user to upload the visual media file; the data is then transformed in a web-compliant format, supporting multi-resolution encoding, compression, and progressive transmission. At the end of the data-processing phase the user receives an email containing the URL of the published asset. Through this URL the user can access a web-based presentation that enables content creators, but also end users, to interactively explore the published media. Finally, the Visual Media Service provides a full set of interactive tools for customizing the resulting web-based presentation.Project(s): ARIADNEplus, ARIADNE , PARTHENOS , EOSCpilot

Automating large 3D dataset publication in a web-based multimedia repository
Potenziani M., Fritsch B., Dellepiane M., Scopigno R.
Online publishing of almost every type of 3D data has become a quasi-standard routine. Nevertheless, the integration in a web page of a single 3D model, or of a predefined restricted set of models, raises different issues compared to an efficient and effective integration of thousands of them in an online repository. In this case it is mandatory to have an automatized pipeline to prepare and homogenize the dataset. The pipeline should be able to automatically wrap 3D data in all conditions, and display every single model with the best scene setup without any (or with a minimal) interaction by the database maintainers. This paper, retracing the steps of a recent real application case, aims at showing all the faced issues (and the adopted solutions) to publish a large and heterogeneous three-dimensional dataset in a web specialized repository. We want to introduce a valid and reusable strategy, starting from the description of the pipeline adopted for data pre-processing and moving to the choices made in the 3D viewer implementation. The paper concludes with a discussion on the actual state of the integration of 3D data with the other multimedia informative layers.Source: Smart Tools and Apps in computer Graphics, Genova, Italy, 3-4 October 2016

Through this White Paper, which gathers contributions from experts of 3D data as well as professionals concerned with the interoperability and sustainability of 3D research data, the PARTHENOS project aims at highlighting some of the current issues they have to face, with possible specific points according to the discipline, and potential practices and methodologies to deal with these issues. During the workshop, several tools to deal with these issues have been introduced and confronted with the participants' experiences, this White Paper now intends to go further by also integrating participants feedbacks and suggestions of potential improvements. Therefore, even if the focus is put on specific tools, the main goal is to contribute to the development of standardized good practices related to the sharing, publication, storage and long-term preservation of 3D data.Source: ISTI Technical Reports, 2019

3DHOP: 3D heritage online presenter
Potenziani M., Callieri M., Dellepiane M., Corsini M., Ponchio F., Scopigno R.
3D Heritage Online Presenter (3DHOP) is a framework for the creation of advanced web-based visual presentations of high-resolution 3D content 3DHOP has been designed to cope with the specific needs of the Cultural Heritage (CH) field. By using multiresolution encoding, it is able to efficiently stream high-resolution 3D models (such as the sampled models usually employed in CH applications); it provides a series of ready-to-use templates and examples tailored for the presentation of CH artifacts; it interconnects the 3D visualization with the rest of the webpage DOM, making it possible to create integrated presentations schemes (3D + multimedia). In its design and development, we paid particular attention to three factors: easiness of use, smooth learning curve and performances. Thanks to its modular nature and a declarative-like setup, it is easy to learn, configure, and customize at different levels, depending on the programming skills of the user. This allows people with different background to always obtain the required power and flexibility from the framework. 3DHOP is written in JavaScript and it is based on the SpiderGL library, which employs the WebGL subset of HTML5, implementing plugin-free 3D rendering on many web browsers. In this paper we present the capabilities and characteristics of the 3DHOP framework, using different examples based on concrete projects.Source: Computers & graphics 52 (2015): 129–141. doi:10.1016/j.cag.2015.07.001

3DHOP una piattaforma flessibile per la pubblicazione e visualizzazione su Web dei risultati di digitalizzazioni 3D
Potenziani M., Callieri M., Dellepiane M., Corsini M., Ponchio F., Scopigno R.
3DHOP (3D Heritage Online Presenter) is an innovative technological solution for the advanced presentation of high-resolution 3D content on the Web. The design of this tool has been focused towards the Cultural Heritage (CH) field, even though its versatility makes it a general-purpose instrument. 3DHOP is particularly suitable for the online presentation of CH artifacts due to its main features: the capability to efficiently stream high-resolution 3D models (as the ones coming from 3D scanning which are usually employed in CH); the possibility to build integrated presentations schemes by interconnecting the viewer to the rest of web pages elements; and, finally, the ready-to-use templates and examples of configuration focused towards CH applications. In its design and development, we put particular attention on three factors: easiness of use, smooth learning curve and performances. 3DHOP is written in JavaScript and it uses the WebGL subset of HTML5 for efficient rendering. Thanks to its modular nature, and a declarative-like setup, it is easy to learn and may be configured and customized at different levels, making it accessible for people without skilled knowledge in Computer Graphics (CG) programming. In this paper we present capabilities and characteristics of the third release of this tool, using some examples based on real-world projects.Source: Archeomatica (Roma) 6 (2015): 6–11. doi:10.48258/arc.v6i4.1216

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

Digital Study and Web-based Documentation of the Colour and Gilding on Ancient Marble Artworks
Siotto E., Palma G., Potenziani M., Scopigno R.
Greek and Roman marble artworks have been deeply studied from a typological and stylistic point of view, while there is still a limited knowledge on the pigments, dyes, binders and technical expedients used by Roman artists. In a renewed scientific interest towards the ancient polychromy (colour and gilding), a digital methodological and multidisciplinary approach can provide valuable information to better investigate and understand this fundamental aspect and to get a complete sense on Greek and Roman marble artworks. Following this research direction, the paper proposes a systematic methodological process defined to detect, document and visualize the preserved (and in some cases the digital reconstructed) original colour and gilding on Roman marble sarcophagi (II-IV century AD). The process defines a working pipeline that, starting from the selection of the artefact to study, proposes a set of investigation steps to improve our knowledge of its original painting. These steps include the direct virtual inspection, the archaeological and historical research, the on-site scientific investigation by multispectral imaging, spectroscopic and elemental analysis (eventually supported by micro-invasive techniques performed in laboratory), the accurate polychrome surface acquisition by colour calibrated 2D images. All the data produced are integrated with a high-resolution 3D model to support enhanced analysis and comparison and to create a digital 3D polychrome reconstruction by virtual painting. Finally, all those data are also made accessible on the web by using a cutting edge platform for visual media publication and interactive 3D visualization. This systematic and multidisciplinary process was tested on the so-called 'Annona sarcophagus' (Museo Nazionale Romano - Palazzo Massimo, inv. no. 40799).Source: Digital Heritage International Congress, pp. 239–246, Granada, 28/09/2015-02/10/2015

Jackson Pollock: Alchemy in 3D
Callieri M., Pingi P., Potenziani M., Dellepiane M., Pavoni G., Lureau A., Scopigno R.
For the exhibition "Alchemy of Jackson Pollock. Discovering the Artist at Work" (February - October 2015, Peggy Guggenheim Collection, Venice), the ISTI-CNR Visual Computing Laboratory created an interactive kiosk to explore the geometry of the painting Alchemy by Jackson Pollock. The kiosk created aims to show the technique and secrets of the artist at work, and enriches an innovative and successful exhibition (more than 180,000 visitors in eight months), replicated shortly afterwards in the same form at the Guggenheim Collection Museum in New York, and adapted for the traveling exhibition "The Art of Science" held in 2021 in Mexico and 2022 in Chile). The interactive kiosk, entirely developed by ISTI-CNR Visual Computing Laboratory, allows you to view the high-resolution 3D model of the entire painting through a touch-screen. The visitor can closely observe the geometry and color of the painting, move the light to appreciate its surface, and select the hot-spots that highlight areas of interest. The kiosk was developed with HTML/JavaScript technology, and 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 for the exhibition) but at the same time publication on the web. The generation of multiresolution 3D models, and their web visualization, is managed by the Nexus, SpiderGL, and 3DHOP software, developed by ISTI-CNR Visual Computing Laboratory. The multimedia product "Jackson Pollock: Alchemy in 3D" was nominated in the "Best Use of DH For Public Engagement" category at the Digital Humanities 2015 Awards, placing first.

An advanced solution for publishing 3D content on the Web
Potenziani M., Corsini M., Callieri M., Di Benedetto M., Ponchio F., Dellepiane M., Scopigno R.
The deployment of 3D content on the Web gained momentum in many contexts. The Cultural Heritage field is a good example, since 3D data need to be published on the Web for many different purposes (presenting museum collections, displaying virtual reconstruction of ancient sites, showing connections between artefacts of interest, etc.); moreover, 3D data are often paired by other multimedia information and, finally, solutions should be cheap and high-fidelity. The current approach for developing 3D graphics applications on the web is to employ WebGL, a graphics javascript API that is embedded in modern web browsers. WebGL was derived from the standard OpenGL graphics library and it has been recently adopted by all the major web browsers. Thanks to this, people that access a web site based on WebGL do not need to install any additional plugins or other applications to use the interactive 3D content of the web page. The main problem related with the use of WebGL is the substantial technical skills the developers should master (such as web design, Javascript programming and knowledge of Computer Graphics) in order to implement an application. We present 3DHop (3D Heritage Online Presenter), an advance technological solution that allows people without high/mid level programming skills to be able to publish 3D content on the Web in several forms. This technology consists in a set of components and templates for the online visualization that have in common the characteristics to be easily modifiable with a minimal effort to obtain the desired final effect. This technology has been developed in the context of a few EU projects and it has been already used in Virtual Museums projects. 3DHop is now reaching its maturity and becomes a solid tool open to the Cultural Heritage community, reducing the learning curve and speeding up the implementation of virtual museums and of on-line interactive presentations. From a technical point of view, 3DHop is based on SpiderGL, a support library built on top of WebGL and developed by CNR-ISTI. A brief overview of this library will also be given in the presentation.Source: MWF 2014 - Museums and the Web Florence 2014, Florence, Italy, 18-21 February 2014
