Abstract:
This paper presents techniques for
interactively visualizing tensor fields
using deformations.
The conceptual idea behind this approach
is to allow the tensor field to manifest
its influence on idealized objects placed
within the tensor field.
This is similar, though not exactly the same,
to surfaces deforming under load in order
to relieve built up stress and strain.
We illustrate the effectiveness of the Deviator-Isotropic
tensor decomposition in deformation visualizations of CFD
strain rate.
We also investigate how directional flow
techniques can be extended to distinguish
between regions of tensile versus compressive forces.

Movies:
The following movies are rather large and require a Quicktime
movie player or plug in.
The audio recording level is very low, so you will also
need to crank up your audio playback level.
