abstract = {Visualized data often have dubious origins and quality. Different
forms of uncertainty and errors are also introduced as the data
are derived, transformed, interpolated, and finally rendered. In
the absence of integrated presentation of data and uncertainty,
the analysis of the visualization is incomplete at best and often
leads to inaccurate or incorrect conclusions. This paper surveys
techniques for presenting data together with uncertainty. These
uncertainty visualization techniques present data in such a manner
that users are made aware of the locations and degree of
uncertainties in their data so as to make more informed analyses
and decisions. The techniques include adding glyphs, adding
geometry, modifying geometry, modifying attributes, animation,
sonification, and psycho-visual approaches. We present our results
in uncertainty visualization for environmental visualization,
surface interpolation, global illumination with radiosity, flow
visualization, and figure animation. We also present a
classification of the possibilities in uncertainty visualization,
and locate our contributions within this classification.},
