Abstract
In this paper we present a high-quality image-space
approach to pen-and-ink illustration that works at interactive framerates
while allowing for a large variety of different drawing styles. Our algorithm
features frame-to-frame coherence, that is, individual strokes move continuously
from frame to frame with continuous changes of the input image. We show
that our approach is able to both reproduce the tone of an input image,
and (depending on the drawing style) to preserve high-frequency detail
in the input image. Finally, while our basic algorithm only requires an
image as input, we can make use additional of 3D information where available
to provide a larger variety of drawing styles.
This work has been published
at the Eurographics Workshop on Rendering, 2002 (and our tiger is one
of the cover images for the proceedings).
Additional Material
Here we provide some additional images to
illustrate the quality of our method. The PostScript files contain images
at 300 DPI resolution (these print twice as large as the versions in the
paper).
