Talk: Optimal Streamlines and Streamsurfaces for 3D Flow Visualization

Date: Friday 9th of May, 1 pm
Room: INF E023

Streamlines and Streamsurfaces are standard tools for the visual analysis of flow data. Nevertheless, their applications still poses challenges concerning their extraction, integration, and visualization.

In the talk, we tackle three problems:

·         the selection of suitable stream lines,

·         a stable integration of stream surfaces,

·         the selection of suitable stream surfaces.

We show that these problems can and should be formulated as global optimization problems. We present the respective error functionals to be minimized and show solutions for several test cases.
