abstract = "Scientific visualization techniques create images attempting to
reveal complex structures and phenomena. Illustrative techniques
have been incorporated to scientific visualization systems in
order to improve the expressiveness of such images. The rendering
of feature lines is an important technique for better conveying
surface shapes. In this paper, we propose to combine volume
visualization of unstructured meshes with direct rendering of
illustrated isosurfaces. This is accomplished by extending a
GPU-based ray-casting algorithm to incorporate illustration with
photic extremum lines, a type of feature lines that captures
sudden change of luminance, conveying shapes in a perceptually
correct way.",
