Abstract:We introduce Flexible Trees, a sketch-based layout adjustment technique. Although numerous tree layout algorithms exist, these algorithms are usually bound to fit within standard shapes such as rectangles, circles and triangles. In order to provide the possibility of interactively customizing a tree layout, we offer a free-form sketchbased interaction through which one can redefine the boundary constraints for the tree layouts by combining ray-line intersection and line segment intersection. Flexible Trees off… Show more
