Abstract:


    Motion provides strong visual cues for the perception of shape and depth, as demonstrated by cognitive scientists and visual artists. We present a novel visualization technique that uses particle systems to add supplemental motion cues. Based on a set of rules following perceptual and physical principles, particles flowing over the surface of an object not only bring out, but also attract attention to essential shape information of the object that might not be readily visible with conventional rendering. Replacing still images with animations in this fashion, we show with both surface and volumetric models that the resulting visualizations effectively enhance the perception of three-dimensional shape and structure.
