An Improved Cellular Automata Model for Simulation of Ink-wash Diffusion Effect

从水墨动态扩散机理分析着手,对元胞自动机模型进行了改进,融入了能真实表征水墨扩散效果的特性因素。首次引入了纤维元的容墨和积墨状态,并采用量化方法简化和建立了墨粒子迁移和水蒸发演变规则。实验结果表明,本文所改进的元胞自动机模型大大增强了水墨扩散的随机性和动态性,仿真效果更趋真实。同时,对水墨扩散效果的仿真具有普适性,借助3维建模与笔法的建立,可进行各种3维水墨效果与笔法的数字实现。

Beginning with the analysis of the ink-wash dynamic diffusion mechanism, an improved Cellular Automata（CA） model based on the characteristic factors that can reflect the effect of ink-wash diffusion more naturally is presented in this paper. The ink-accommodating and ink-adhering concept for the ink status of the fiber cell is introduced for the first time. The evolvement rules of the ink-particle movement and the water evaporating are simplified and established by the quantizing status. The simulation results show that the randomicity and motility of the ink-wash diffusion are visibly enhanced by this CA model and the simulated effect is more real than former models. At the same time, the widespread applicability for the simulated effect of ink-wash diffusion is provided by this CA method. The various 3D and styles of inkwash brush effect will be digitally realized by 3D modeling and writing brush models.
