基于经验的中国水墨画毛笔笔道的仿真

综合物理模型和经验模型的优点,本文提出一种基于经验的一维笔模型.该模型创造性地采用"死元"和"活元"的思想模拟毛笔的分叉、飞白等效果.在此基础上,将毛笔笔道抽象成为笔道模型,使用路径来控制毛笔运动轨迹的瞬时状态,并定义了一套完整的水墨传输机制.笔模型和笔道模型将构成整个笔道仿真体系,该体系模拟了毛笔的真实绘制过程,其结果将传递给纸模型进行扩散,以实现仿真各种笔道效果的最终目标.

Empirically based simulation of brush stroke in Chinese ink wash drawing

Integrating the advantages of previous physical models and empirical models,we propose an empirical one dimensional brush model,which innovatively uses "dead cell" and "dynamic cell" to simulate the bifurcation and half-dry effect of brush. Based on this model,the brush stroke can be abstracted into a stroke model,which uses path to track the instantaneous state of the brush movement. Meanwhile,we define a whole mechanism of ink transmission. Brush model and the stroke model compose the entire stroke simulation system,which reproduces the real drawing process and the result is transmitted to the paper model for diffusion to achieve all kinds of brush strokes simulate.
