One of the most challenging work in non-photorealistic rendering research field is to studies of the simulation of Chinese ink wash drawing. By analyzing the Chinese ink wash drawing material and ink-wash diffusion mechanism

a new method based on genetic algorithm is presented to model the diffusion effect. The method first simulates the diffusion effect by binary gene encoding

initializing population and gene mutation. It constructs a list of mapping that describes the correspondence of Minkowski distance to the rate of gene mutation so that gene mutation can happen suitably by itself. As a result

modeling the diffusion of Chinese ink wash drawing can be finished automatically. All kinds of ink wash diffusion effects can be realized by some parameters

such as the scale of population

paper cell fiber threshold and so on; Furthermore

to improve the diffusion effect made by the simulation system above

the model uses Ashikhmin algorithm and Gaussian Distribution to simulate the characteristic of xuan-paper to make the diffusion effect with more fidelity. Experimental results demonstrate that this method simulates the typical effects of Chinese ink wash drawing successfully.
