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. Key words: 3D digitization, virtual archaeology, cultural heritage, documentation, web-based 3D visualization, restoration Resumen: Las tecnologías digitales están ahora maduras para producir réplicas digitales de alta calidad de valores activos del patrimonio cultural (CH). Los resultados de la investigación producidos en la última década han mostrado una evolución impresionante y una consolidación de las tecnologías para la captura de modelos digitales tridimensionales (3D) de alta calidad, que abarcan la geometría y el color. Lo que queda aún por resolver está relacionado con la forma de distribuir los datos y el conocimiento relacionado con la sociedad. La web es hoy en día el principal canal utilizado para divulgar el conocimiento. Las soluciones comerciales nuevas relacionadas con la publicación en la red de datos en 3D se están consolidando y convirtiendo en un estándar de facto para muchas aplicaciones (comercio electrónico, productos industriales, educación, etc.). En este escenario, el patrimonio cultural es un dominio muy específico, que requiere soluciones muy flexibles. Se presentan algunas experiencias recientes, destinadas a proporcionar un apoyo al archivo de los datos arqueológicos 3D, la publicación web de los resultados de digitalización de muy alta resolución que permiten finalmente la documentación de trabajos de restauración complejos. Todos estos ejemplos se han implementado recientemente en la plataforma 3D Heritage Online Presenter (3DHOP) de código abierto, desarrollada en el CNR-ISTI.

Introduction panoramic/360º images; standard videos or omnidirectional videos) or the geometrical/shape Multiple digital technologies are experimented in Digital characteristics of a CH artefact or scene (using one of the Humanities (DH); those instruments are going to play an many 3D representation incarnations). important role in the study, dissemination and didactical A number of enabling technologies have been developed activities related to our Cultural Heritage (CH). These and matured in the last years to sample the artworks of technologies cover many different types of applications interest. Sampling devices are then paired by processing and are the results of intensive research in many scientific technologies, data optimization tools (e.g. providing domains (not just Computer Science but also Optics, simplification and multiresolution features to increase the Physics, Chemistry, etc.). More specifically, Computer usability of very high resolution samplings), efficient Science is offering many different opportunities to archival systems, search and retrieval facilities and, manage visual data at unprecedented levels of accuracy finally, tools for web presentation. and ease of use. The term visual data is intended here to encompass all digital visual representations we can adopt The latter domain is the main focus of this paper. to produce a useful sampling of either the visual Nowadays the web is the place consulted by everybody characteristics (by means of: standard 2D images; more searching for knowledge or digital content.
