应用分形仿真水墨扩散轮廓

针对水墨在宣纸上扩散后会出现较明显的具有自相似特性的轮廓线这一特点，提出一种仿真中国水墨画扩散边界的实现方法．该方法通过流体仿真模型产生扩散笔迹，利用分形在扩散笔迹的最外层模拟一条不规则的扩散边界，并填充两者之间的空隙，使得扩散效果更自然、逼真．实验结果表明，借助分形模拟的扩散效果接近真实的水墨画效果．

Fractal-Based Simulation of the Diffusion Effect of Chinese Ink Wash Drawing

In Chinese ink wash drawing, a self-similar silhouette is generated on Xuan paper while ink diffuses. An approach based on fractal is presented to simulate the diffusion border. This approach first generates a diffusion stroke through fluid simulation model. Then it simulates an irregular outer border on the diffusion stroke. Furthermore, it fills the interspace between them to make the diffusion effect more natural and true to life. Experimental results demonstrate that the diffusion effect simulated by fractal is similar to the real effect of ink wash drawing.
