Non photo realistic rendering for visual analysis of medical data

From <http://www.cs.princeton.edu/gfx/pubs/Burns_2005_LDF/index.php>

"Abstract: Renderings of volumetric data have become an important data
analysis
tool for applications ranging from medicine to scientific simulation.
We propose a volumetric drawing system that directly extracts sparse
linear features, such as silhouettes and suggestive contours, using a
temporally coherent seed-and-traverse framework. In contrast to
previous methods based on isosurfaces or nonrefractive transparency,
producing these drawings requires examining an asymptotically smaller
subset of the data, leading to efficiency on large data sets. In
addition, the resulting imagery is often more comprehensible than
standard rendering styles, since it focuses attention on important
features in the data. We test our algorithms on datasets up to
$512^3$, demonstrating interactive extraction and rendering of line
drawings in a variety of drawing styles. "

Enjoy.
