Interactive deformations from tensor fields
Ed Boring, Alex Pang · 1998
This paper presents techniques for interactively visualizing ten-sor fields using deformations. The conceptual idea behind this ap-proach is to allow the tensor field to manifest its influence on ide-alized 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 visu-alizations of CFD strain rate. We also investigate how directional flow techniques can be extended to distinguish between regions of tensile versus compressive forces.
