Virtual reconstruction as a scientific tool: The extended matrix and source-based modelling approach

The focus of this paper is to highlight what are the major theoretical issues of virtual reconstruction in archeology (black-box effect, palimpsest-effect, role of accuracy) and explain how the Extended Matrix approach was designed to respond to these specific needs. The Extended Matrix (EM) is a tool that extends the stratigraphic approach to the recording and managing of the re-constructive record: one of the goals of this research is to prove that the stratigraphic method, intended as chronological reading of a spatial context, is able to compose a com- plete and multidimensional re-constructive record through the EM. This approach can improve the quality of virtual reconstructions non only for scientific purposes but also in the industry of Virtual Museums and Digital Libraries.
