Rapid Visualization for Cultural Heritage Diagnostics

A thorough digital record of a culturally significant artifact or site can be collected using a variety of diagnostic imaging techniques, establishing a baseline for characterizing its state of preservation. This massive digital record, which includes data from multispectral photography, three-dimensional scanning, and material characterization, among others, provides the equivalent of a digital clinical chart for the site. We present a visual analytics framework for the interactive and intuitive synthesis, visualization, and analysis of this record, using a point-based data representation and rendering paradigm, and illustrate its capabilities in the context of a set of case studies.
