Abstract We present algorithms that allow for real-time rendering of 3D-scenes with a watercolor painting appearance. Our approach
provides an appropriate simplification of the visual complexity, imitates characteristic natural effects of watercolor, and
provides two essential painting techniques: the wet-on-wet and the wet-on-dry painting. We concentrate on efficient algorithms
based on image space processing rather than on an exact simulation. This allows for the real-time rendering of 3D-scenes.
During an animation a high frame-to-frame coherence can be achieved due to a stable segmentation scheme. Finally, we seamlessly
integrate a smooth illumination into the watercolor renderings using information from the 3D-scene.

Thomas Luft graduated in 1997 from Dresden University of Technology. Currently, he works as a Ph.D. student under the supervision of
Prof. Oliver Deussen. His research interests encompass non-photorealistic rendering and real-time graphics.
Oliver Deussen graduated in 1991 from Karlsruhe University of Technology where he also received his Ph.D. degree in 1996. He worked as a
postdoc researcher from 1996 until 2000 at Otto-von-Guericke University of Magdeburg and was associate professor for computer
graphics at the Dresden University of Technology from 2000 until 2003. Since then he is a full professor for computer graphics
and media informatics at the University of Konstanz. His research interests encompass non-photorealistic rendering, modeling
and rendering of complex botanic objects as well as information visualization.
