VR and Holographic Information System for the Conservation Project

This paper presents an advanced digital workflow that integrates virtual reality and holographic visualization systems to support conservation planning and heritage management. The research addresses a common limitation in heritage digitization: although laser scanning and photogrammetry produce accurate 3D datasets, these models are often reduced to traditional 2D drawings, losing spatial richness and informational potential. To overcome this issue, the authors propose the direct use of point clouds enriched with semantic data, linked to a PostgreSQL database and visualized through immersive and collaborative environments. A VR application developed in Unity enables first-person exploration of the surveyed site, hotspot creation, and on-site compilation of conservation factsheets. In parallel, a Euclideon Hologram Table allows multiple users to inspect the same three-dimensional dataset simultaneously, facilitating collective analysis and project discussion. The methodology demonstrates how point clouds can become operative information systems rather than passive survey outputs. The study highlights the educational and professional value of combining accurate survey data, shared interfaces, and interactive visualization tools for heritage preservation, diagnosis, and reuse strategies.
