Tensor Field Visualization Using Eulerian Fluid Simulation

摘要

In symmetric second order tensor fields, the colinearity and coplanarity of the represented structures are properties of major interest. In this paper, we present a method that induces the human perceptual system to extract these structures by using an Eulerian fluid simulation. Differently of previous approaches, our model explores the interaction between the particles to improve the perception of the underlying structures in the tensor field. The main contribution is the introduction of a tensor based advection step and a gradient based external force, suitable for viewing colinear and coplanar structures. Our experimental results show that fluids are suitable to reveal curves, surfaces and their connec- tions.
