Comparative Flow Visualizaiton
There are many situations where one needs to compare two or more datasets.
It may be to compare different models, different resolutions,
differences in algorithms, different experimental results, etc.
There is therefore a need for comparative visualization tools
to help analyze the differences.
This paper focuses on comparative visualization tools for
analyzing flow or vector datasets.
The techniques presented allow one to compare individual
streamlines and streamribbons as well as a dense field of streamlines.
These comparison methods
can also be used to study differences in vortex cores
that are represented as polylines.
