Rappresentazioni per l'archeologia

3D scanning systems allow high detailed survey, with speedy data acquisitions and good accuracy: they are suitably applied in the Cultural Heritage documentation field. The incoming spread of these techniques shade more and more measure into representation; there’s no doubt about the more suggestive capabilities of points clouds (viewed in real time and interactively explorable), instead of a long list of coordinates and attributes. The high density acquisition seems to guarantee a complete object description even without the necessary interpolation aimed to obtain continuous data. However, when it’s necessary to leave the evocative points cloud, that nowadays has raise to a paradigmatic new representation, we need to take in great esteem the information contents and study how to replace undifferentiated point data with vector ones. This paper shows some survey experiences in archaeological field. We evaluate skills and limits of a large kind of representation available nowadays.
