Interactive Comparison of Scalar Fields Based on Largest Contours with Applications to Flow Visualization
Found in: IEEE Transactions on Visualization and Computer Graphics
By Dominic Schneider, Alexander Wiebel, Hamish Carr, Mario Hlawitschka, Gerik Scheuermann
Issue Date:November 2008
pp. 1475-1482
Understanding fluid flow data, especially vortices, is still a challenging task. Sophisticated visualization tools help to gain insight. In this paper, we present a novel approach for the interactive comparison of scalar fields using isosurfaces, and its a...
 
The Topological Effects of Smoothing
Found in: IEEE Transactions on Visualization and Computer Graphics
By Sohail Shafii,Scott E. Dillard,Mario Hlawitschka,Bernd Hamann
Issue Date:January 2012
pp. 160-172
Scientific data sets generated by numerical simulations or experimental measurements often contain a substantial amount of noise. Smoothing the data removes noise but can have potentially drastic effects on the qualitative nature of the data, thereby influ...
 
HOT- Lines: Tracking Lines in Higher Order Tensor Fields
Found in: Visualization Conference, IEEE
By Mario Hlawitschka, Gerik Scheuermann
Issue Date:October 2005
pp. 4
<p>Tensors occur in many areas of science and engineering. Especially, they are used to describe charge, mass and energy transport (i.e. electrical conductivity tensor, diffusion tensor, thermal conduction tensor resp.) If the locale transport patter...
