为了满足人们在美工设计中对计算机国画艺术效果仿真的需求,研究和分析了水墨扩散LBE(lattice Boltzmann equation,网格波尔兹曼)算法,提出运用亮度决定水粒子的初始分布,用CMY粒子进行扩散模拟.通过对LBE算法进一步推导而提出疑问,并对扩散及受阻方程进行修正.使用Wintab 1.1压感设备接口完成用户压感数据的读取,借助图像处理函数库IPL98 2.0进行扩散实验数据结构和实验流程设计,实现了国画水墨扩散效果的模拟,证明了该方法的可行性和有效性.

To meet the requirement of computer simulation of Chinese painting art effect that people using in art design,the algorithm LBE(lattice Boltzmann equation)is researched and analyzed.The way to determine the primary water particle distribution according to lightness and implement diffusion simulation by using CMY particle is presented.The problems is presented based on the further reasoning of the algorithm are brought forward,the fluid article function and resistance factor equations are modified.By using the pressure sensitive equipment interface Wintab 1.1 to read the user input pressure data and IPL (image processing library)98 2.0,we design the data structure and process of the article diffusion experiment and achieve the effect simulation of water-ink diffusion in Chinese painting which demonstrated the feasibility and the effectiveness of the method.
