Abstract:
We present a system for rendering 3D animations in the style of line drawings. We use a highly parameterized line model in order to determine the appearance of a line. This model allows us to render characteristic line deviations that remain--in contrast to existing non-photorealistic rendering systems--frame coherent. Other inconsistencies which result from intersection and visibility changes during an animation are prevented by a path reconstruction method. Furthermore, we implemented a keyframing for linestyle parameters which enables us to extend illustration techniques like simplification of a scene or the placement of emphasis on certain objects to the field of 3D computer animation.
