Narrative Virtual Museum of Appia Archaeological Park (2005-2006, temporary exhibits). The project regards activities, technologies and digital solutions connected with an interdisciplinary approach, carried out by CNR ITABC and the Archaeological Superintendency of Rome. The goal of the project is to realize a digital archive of the monuments of the Archaeological Park of Ancient Via Appia, employing many different technologies for 3D representation of the landscape and integrating instruments for topographic relief and methodologies of surveying on site (DGPS, laser total station, photogrammetry, 3D laser scanning, photo and video acquisition), according to the level of detail required. All the data are successively elaborated to obtain a correct geometric model of the landscape, implemented in a Real time OpenGL application where the user can interact with many hierarchical levels of contents. The project presents a methodological approach, oriented towards real time desktop OpenGL applications, in which the incremented cognitive value of scientific 3D reconstruction can be fully integrated with the complex informative system, composed by metadata associated. A multidisciplinary critical interpretation of the landscape, considered as an ecosystem, becomes possible, the virtual archaeology becomes cognitive archaeology, the virtual reality augmented reality. Developed by CNR ITABC.
