abstract = {Indirect volume rendering is a widespread method for the display
of volume datasets. It is based on the extraction of polygonal
isosurfaces from volumetric data, which are then rendered using
conventional rasterization methods. Whereas this rendering
approach is fast and relatively easy to implement, it cannot
easily provide an understandable display of structures occluded by
the directly visible iso-surface. Simple approaches like
alpha-blending for transparency when drawing the iso-surface often
generate a visually complex output, which is difficult to
interpret. Moreover, such methods can significantly increase the
computational complexity of the rendering process. In this paper,
we therefore propose a new approach for the illustrative indirect
rendering of volume data in real-time. This algorithm emphasizes
the silhouette of objects represented by the iso-surface.
Additionally, shading intensities on objects are reproduced with a
monochrome hatching technique. Using a specially designed two-pass
rendering process, structures behind the front layer of the
iso-surface are automatically extracted with a depth peeling
method. The shapes of these hidden structures are also displayed
as silhouette outlines. As an additional option, the geometry of
explicitly specified inner objects can be displayed with constant
translucency. Although these inner objects always remain visible,
a specific shading and depth attenuation method is used to convey
the depth relationships.},
