abstract = {In this paper we present a fast visualization technique for
volumetric data, which is based on a recent nonphotorealistic
rendering technique. Our new approach enables alternative insights
into 3D data-sets (compared to traditional approaches such as
direct volume rendering or iso-surface rendering). Object
contours, which usually are characterized by locally high gradient
values, are visualized regardless of their density values.
Cumbersome tuning of transfer functions, as usually needed for
setting up DVR views, for example, is avoided. Instead, a small
number of parameters is available to adjust the non-photorealistic
display. Based on the magnitude of local gradient information as
well as on the angle between viewing direction and gradient
vector, data-values are mapped to visual properties (color,
opacity), which then are combined to form the rendered image (MIP
is proposed as the default compositing stragtegy here). Due to the
fast implementation of this alternative rendering approach, it is
possible to interactively investigate the 3D data, and quickly
learn about internal structures. Several further extensions of our
new approach, such as level lines are also presented in this
paper.},
