Images of Span Space

These images show what various data sets look like in span space (introduced by Livnat et. al. 1996).

The color map used is shown in the bottom right corner of each image. Brighter colors (to the right of the color map) represent higher point density. Density values are logarithmically scaled to emphasize both high and low values.

Blowups of interesting ranges appear to the right of the overall images.

Images of a representative isosurface from most data sets are available by following the (image) links.
