In the forecasts of 2019, the trend of the VR AR MR and AI sector was growing strongly; due to the pandemic events, real growth in the following two years has largely exceeded expectations. The possi-bility of interacting remotely by VR AR and MR modes during the pandemic was one of the solutions that made possible to overcome distances and barriers. As part of the 3DLAB Sicily project financed by the Sicily region and aimed at enhancing the resources of the cultural heritage of the territory, the De-partment of Civil Engineering and Architecture of the University of Catania (DICAR) participates in developing VR, AR, MR by a research team pertaining to the disciplines of design and representation, for the study of some UNESCO sites. The acquisitions of the models have been started using active and passive sensors for various cultural heritage; the case studies range from protohistoric archeology to medieval military architecture to the Baroque of the Val di Noto. The aim of the project is the creation of 3D navigable models for VR and AR viewers, or for two and three-walled VR caves that have been built as part of the same project. Below are the procedures, considerations and evaluations for the first results obtained.
