Abstract:
We present an algorithm for simulating the cracks found in Batik wax painting and dyeing technique used to make images on cloth. The algorithm produces cracks similar to those found in batik due to the wax cracking in the dyeing process. The method is unlike earlier simulation techniques used in computer graphics, in that it is based on the Distance Transform algorithm rather than on a physically based simulation such as using spring mass meshes or finite element methods. Such methods can be difficult to implement and computationally costly due to the large numbers of equations that need to be solved. In contrast, our method is simple to implement and takes only a few seconds to produce convincing patterns that capture many of the characteristics of the crack patterns found in real Batik cloth.
