^{Block dataset}

The following pictures are made from a dataset representing the flow around a block. Because the dataset is very big, the visualisations show not the whole vectorfield, but interesting parts of it, like the region around the block or the "waves" after the block. Sometimes only some slices of the 64 slices in the z-direction are used. The block geometry can be visualised optionally, with or without textures.

^{Smog dataset}

This is a dataset which contains the windfield and ozone concentration over Europe in the month juli 1989 sampled at a 4 hour interval at four different layers in the atmosphere. The visualisation show just one tíme step of 176. Because the data consist of only  4 slices in z-direction, the results appear to be somewhat  2-dimensional.
