abstract = {This report presents a novel vector rendering pipeline that allows
us to easily break the pixel barrier and create high-quality
illustrations. Recently, most graphic research has been directed
towards rendering pixel images that appear realistic. In contrast,
we investigate the generation of vector graphic illustrations
using non-photorealistic techniques such as line rendering and
Gooch shading. By combining vector output from both shading and
line rendering of 3D models we create high-quality illustrations
that can directly be used in print reproduction. Our approach uses
a vector graphic pipeline that tracks multiple attributes of
strokes and uses them for stylization. This allows to have
multiple layers of line rendering such as different stroke types
or visible and hidden parts of strokes, each treated differently
according to specific stylization rules. Using high quality vector
graphics (as opposed to pixel renditions) for representing
illustration is essential, in particular, in the print
reproduction process. Foremost, vector graphics can be reproduced
at any desired resolution; they do not suffer from the resolution
dependence of pixel images. In addition, only vector graphics can
capture fine details accurately while maintaining a reasonable
file size. Finally, vector graphics do not need to be half-toned
when printed as long as spot colors are used. Even if some layers
of the image use, e. g., shading, only those parts of the vector
graphic need to be half-toned that actually do not make use of the
available spot colors. Thus, we can combine both shading and line
layers without compromising print quality.},
