摘要：

毛笔是中国传统水墨艺术数字实现的关键之一.基于毛笔的特征分析，提出一种渐长型弹簧-子模型，更真实地表征了毛笔的几何构造，建立了仿真毛笔的粒子行为的动力学方程，并利用计算效率较高的Verlet积分方法对其进行数值求解，以有效地提高实时性.仿真结果表明,该方法可以兼顾真实感和实时性，高效地模拟出毛笔的动态效果.

关键词: 毛笔；渐长型弹簧-子模型；动力学方程；Verlet积分方法

Abstract:

Chinese brush is an important tool in the digitalizing Chinese traditional ink-ash art. Based on the analysis of brush traits, a model of springparticle lengthening for simulation of Chinese brush is presented. The geometrical structure of brush is characterized more realistically with a spring which gradually increases in length. A dynamic equation of brush deformation is established based on the Newton’s second law, and solved with the Verlet integral method to improve computation efficiency. Simulations results show that the presented method for simulating Chinese brush and its movement is realistic and effective.

Key words: Chinese brush; spring-article lengthening model; dynamic equation; Verlet integral
