Abstract:
We present a new set of non-photorealistic rendering (NPR) tools for processing video. Our approach is to treat the video as a spacetime volume of image data. Previous tools to process video for an impressionist effect have painted collections of two-dimensional strokes on each successive frame of video. In contrast, we create a set of "rendering solids." Each rendering solid is a function defined over an interval of time; when evaluated at a particular time within that interval, it provides parameters necessary for rendering an NPR primitive. Rendering solids can be rendered interactively, giving immediate feedback to an artist along with the ability to modify styles in real time. Benefits of our approach include: a more unified treatment of the video volumeÕs spatial and temporal dimensions; interactive, aesthetic flexibility and control; and the extension of stylized rendering techniques for video beyond the impressionist styles previously explored. We show example styles inspired by impressionist, cubist, and abstract art of the past century.
