Abstract
We present an image filter that transforms an input line drawing into an image of a fractured surface, where the cracks echo the input drawing. The basis of our algorithm is the Voronoi diagram of a weighted graph, where the distance between nodes is path cost in the graph. Modifying the edge costs gives us control over the placement of region boundaries; we interpret region boundaries as cracks. The rendering of our crack maps into final images is accomplished either by image analogies or by modulation of an uncracked texture.
