Abstract: The existing algorithm of rendering batik crack is improved in this paper. A distance
transform algorithm based flood method is proposed to get good real-time performance, a probability
algorithm is used to find seed point for getting good distribution, a method of adjusting crack shape is
proposed to improve single crack′s shape, and T-junction thickening is controlled by hyperbola for
more like batik crack. Experiments show that these methods can simulate visual features of batik
crack better and have good real-time performance.
