# Open Scientific Visualization Datasets

Datasets are generously hosted by the Scientific Computing and Imaging Institute. The previews are compressed using the ZFP library.

Please, cite individual datasets, if they have BibTeX, to support authors.

All datasets are in little-endian byte order. Dimensions are width x height x depth (e.g., array[depth][height][width] in C).

Data contributions can be made by emailing us the dataset along with its description.
