Perceiving bundles densities with a bump mapping rendering technique. Edges are
rendered as cubic B-splines. (

edge colors are used as a color map (Color figure online)
To remove this clutter and to emphasize high-level edge patterns, the edges are
routed and grouped into bundles. Finally, rendering techniques such as bump
mapping are used to illustrate bundle densities.
