===============================================

to the Research Seminar 'Computer Graphics, Image Processing, and Visualization'

    on Thursday, October 11th, 2018, at 1:15 PM,
    in Room P-702 in the Paulinum, Augustusplatz.

===============================================

A talk will be given by

    Felix Raith
    Image and Signal Processing Group
    Department of Computer Science
    Leipzig University

and is entitled

    "Tensor Field Visualization using Fiber Surfaces of Invariant Space".

Abstract:

    Scientific visualization developed successful methods for scalar and vector
    fields. For tensor fields, however, effective, interactive visualizations
    are still missing despite progress over the last decades. We present a
    general approach for the generation of separating surfaces in symmetric,
    second-order, three-dimensional tensor fields. These surfaces are defined as
    fiber surfaces of the invariant space, i.e. as pre-images of surfaces in the
    range of a complete set of invariants. This approach leads to a
    generalization of the fiber surface algorithm by Klacansky et al. to
    three dimensions in the range. This is due to the fact that the invariant
    space is three-dimensional for symmetric second-order tensors over a spatial
    domain. We present an algorithm for surface construction for simplicial
    grids in the domain and simplicial surfaces in the invariant space. We
    demonstrate our approach by applying it to stress fields from component
    design in mechanical engineering.

On behalf of Professor Scheuermann all those interested are cordially invited to attend.
