Between the Real and the Virtual: 3D visualization in the Cultural Heritage domain - expectations and prospects

The paper discusses two uses of 3D Visualization and Virtual Reality (hereafter VR) of Cultural Heritage (CH) assets: a less used one, in the archaeological / historical research and a more frequent one, as a communication medium in CH museums. While technological effort has been mainly invested in improving the “accuracy” of VR (determined as how truthfully it reproduces the “CH reality”), issues related to scientific requirements, (data transparency, separation between “real” and “virtual”, etc.), are largely neglected, or at least not directly related to the 3D outcome, which may explain why, after more than twenty years of producing VR models, they are still rarely used in the archaeological research. The paper will present a proposal for developing VR tools as such as to be meaningful CH research tools as well as a methodology for designing VR outcomes to be used as a communication medium in CH museums
