The image is a visualization of a vortex breakdown bubble, the area where the dissipation of a vortex results in complicated flow structures. It is an example of a recently developed flow visualization technique, illustrative rendering of integral surfaces.

Illustrative rendering aims to improve shape perception by imitating hand-made illustrations.

Here, it is applied to integral surfaces, which are a commonly used tool for visualizing simulated flow fields. One of the Computer  Graphics and HCI Group’s core research subject is flow visualization.

Illustrative rendering of integral surfaces was developed by members of the Computer Graphics and HCI Group in cooperation with researchers from UC Davis.

The results are part of the paper IRIS: Illustrative Rendering of Integral Surfaces, which was presented at the IEEE Vis Conference 2010 and appeared in IEEE Transactions on Visualization and Computer Graphics (TVCG)
