Abstract
Every project for the development of cultural heritage is founded on at least two premises: an understanding of the individual item and the context in which it is found, and a correct communication of the information acquired, promoting the widest possible fruition of this knowledge by the community. In recent years the use of new technologies for documentation of cultural heritage has become more and more widespread, greatly modifying both acquisition and diffusion of information. However, there is now a need for greater control over cultural content and its correct communication, to ensure not only technical precision, but also integrity of methods and general goals. The following article presents a number of research projects that deal with architectural and urban-historical themes, directed towards a more widespread and active sharing of knowledge and information and favoured by new technologies and the internet, but always with due attention to quality of cultural content. A fundamental aspect is the use of 3D models, since communication of built space is more effective if it is based on criteria of perception. Such systems of visualisation, based on the user’s interaction with the three-dimensional space of the object, have shown themselves to be a valid aid for less expert users. These models have been used above all as focal points to organise various forms of information in different ways: the 3D digital space enables the user more easily to correlate a particular datum, extract, or search item into its context. With further manipulation, these models have been integrated differentially with the real or virtual space, creating cultural paths of strong impact as well as high cultural content. Moreover, the various research projects have considered especially technologies that require no special instrumentation, that are easy to use, inexpensive or preferably open source, but, in any case, reliable as regards the quality of the data processed (metrical, geometrical, and surface).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
