    Supplementary material video for our NPAR 2011 paper (Snaxels on a Plane). Authors: Kevin Karsch, John C. Hart Abstract: While many algorithms exist for tracing various contours for illustrating a meshed object, few algorithms organize these contours into region-bounding closed loops. Tracing closed-loop boundaries on a mesh can be problematic due to switchbacks caused by subtle surface variation, and the organization of these regions into a planar map can lead to many small region components due to imprecision and noise. This paper adapts "snaxels," an energy minimizing active contour method designed for robust mesh processing, and repurposes it to generate visual, shadow and shading contours, and a simplified visual-surface planar map, useful for stylized vector art illustration of the mesh. The snaxel active contours can also track contours as the mesh animates, and frame-to-frame correspondences between snaxels lead to a new method to convert the moving contours on a 3-D animated mesh into 2-D SVG curve animations for efficient embedding in Flash, PowerPoint and other dynamic vector art platforms.

      I made this short film in 1995, during a gap between commercial jobs while working at PDI. All elements are computer-generated. No actual paper, ink, or pigeons were involved. A brief synopsis of the process can be found here: http://otherthings.com/uw/pigeons/brick2.html

        I developed the watercolor look for this film, directed by David Gainey, in 1999. Because David's character design consisted mostly of thin lines, I didn't have to run a true fluid simulation. I was able to achieve the watercolor effect using only image processing and noise synthesis.

        • The New Chair, rough cut (1998)

          A rough cut of part of a short film I started while working at the University of Washington. I did all the animation, and developed the "Loose and Sketchy" rendering style, described in more detail here: http://otherthings.com/uw/loose The character animation is pretty janky overall, though a few of the shots hold up pretty well. I sure have learned a lot since 1998!

          • Experimental Animation 1991-1994

            While working at R/Greenberg Associates in New York, and later at Xaos, Inc. in San Francisco, I spent a lot of my time developing graphics software (mostly involving image processing and particle systems) and then using the software to do my own little animation experiments. Some of these experiments attracted new clients to the studio and were broadcast to the world in the form of commercials or TV bumpers. Others remain unused to this day. Here's a demo reel I put together in 1994.
