Multidimensional data visualization for decay study in cultural heritage: an object-oriented implementation

The scope of this work has been to apply multidimensional data visualization techniques to the study of the ancient building decay events. With this aim we have created new visual tools based on the shape variation (glyph), that with more traditional techniques based on the color have been implemented in object-oriented software programs using the innovative and powerful visualization toolkit (VTK), a free C++ class library for visualization and 3D computer graphics. The data used are climatic, chemical and environmental measurements detected on/near the Roman theatre in the city of Aosta, acquired in the ambit of an Italian research project focused on the restoration of ancient monuments.
