Temporary made permanent: Turning temporary exhibitions into fixed memories

The museum institution deals with the study, the storage and the fruition of cultural heritage. To fulfill these functions the museum uses, as well as the opinion of experts, even the most modern technologies. In this article we present some cases in which the use of digital and virtual reality effectively contributes to increase the knowledge on cultural heritage. In the last years there have been many studies to allow cultural heritage to be preserved with great care, ensuring the memory for scholars but also for future generations. The methods for storing a cultural object are widely studied, but the best techniques to preserve different forms of heritage like temporary or intangible items, are still under discussion. In particular this article refers to the possibility of keeping track of the information contained in a temporary exhibition project, that by its nature exists for a limited amount of time before being finally destroyed or transferred. With the use of standard tools like photogrammetry and three-dimensional modeling we try to define a process in order to turn the temporary into permanent, both for archiving purposes or for allowing the public to access the temporary installation once the physical object has been dismounted.
