Dissemination Techniques for 3D Content Related to Pompeii City Walls

Abstract

The paper presents a methodological framework for the integration, semantic organization and web-based dissemination of heterogeneous 3D archeological datasets. In particular, the study investigates strategies for model optimization, interoperability, multilevel information architecture and scientific visualization of complex archeological sites. The research builds upon an analysis of current workflows for 3D data acquisition, optimization, and dissemination, as well as a critical assessment of existing approaches to digital heritage communication. The proposed workflow supports the integration of datasets acquired at different spatial scales, from urban contexts to architectural elements and individual artifacts, enabling semantic correlation between geometric data and interpretative content. Alongside the technical aspects of model optimization, interoperability and web-based visualization, the research also examines the transmission of tangible and intangible cultural values during the transition from the physical environment to the digital domain. These technical and theoretical aspects are treated as complementary dimensions of a single methodological framework, ensuring consistency of the project in terms of data processing, accessibility, scientific rigor, and heritage interpretation. The workflow proposed is applied to the specific case of the walls of Pompeii, where the complex physical reality of the arche-ological site is accompanied by intangible characteristics, such as ancient techniques of warfare and siege. Using 3D models created during previous phases of the SCORPi ò -NIDI project, the resulting web-based system provides layered access to information, facilitating both scientific analysis and dissemination activities while maintaining traceability of sources and clarity between acquired data and reconstructed hypotheses. The proposed framework contributes to current research on structured digital environments for Cultural Heritage and offers transferable methodologies for the management and dissemination of complex archeological datasets.
