Abstract: This paper describes the architecture of an image and data level
comparative visualization system and experiences using it to study
computational fluid dynamics data and experimental wind tunnel data. We
illustrate how the system can be used to compare data sets from different
sources, data sets with different resolutions and data sets computed by using
different mathematical models of fluid flow. We include recent improvements
including use of the comparison of vector fields, ability to interactively
interrogate the comparisons, addition of new metrics, the latest FEL2.0 and
VisTech libraries, and GUI for a calculator module.
