An Improved Cellular Automata Model for Simulation of Ink-wash Diffusion Effect
仿真水墨扩散效果的元胞自动机改进模型

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 ink-wash brush effect will be digitally realized by 3D modeling and writing brush models.
