Integrating spatial data display with virtual reconstruction

In the process of archaeological excavation, a vast amount of data, much of it three-dimensional in nature, is recorded. In recent years, computer graphics techniques have been applied to the task of visualizing such data. In particular, data visualization has been used to accomplish the virtual reconstruction of site architecture and to enable the display of spatial data distributions using three-dimensional models of site terrain. In the case we present here, these two approaches are integrated in the modeling of a prehistoric pithouse. In order to better visualize artifact distributions in the context of site architecture, surface data is displayed as a layer in a virtual reconstruction viewable at interactive rates. This integration of data display with the architectural model has proven valuable in identifying correlations between distributions of different artifact categories and their spatial proximity to significant architectural features.<>
