Abstract:
A hierarchical approach for designing continuous line illustrations, drawings that consist of a single line, is presented throughout this paper. Users specify a graph that will guide the overall shape of the line illustration, and proceed to assign a series of child graphs to many of its vertices. A line illustration can then be generated by taking all of these graphs into account, allowing us to produce complex drawings that are composed of
several objects. Our approach also allows us to preserve the overall structure and orientation of the line as graphs are inserted or removed from the illustration. We also propose a variety of visual enhancements for our illustrations based on the specified hierarchical graph information and provide several result examples that demonstrate the effectiveness of our approach.
