交互式毛笔书写仿真系统研究

Research Of Interactive Calligraphy Brush Writing Simulation System

针对现有毛笔书写仿真技术中存在毛笔弯曲、扭转变形、水墨传输效果欠佳等问题,提出了一种基于位置动力学构造虚拟毛笔模型的方法。通过设计一种笔头动态变形机制,使毛笔书写在弯曲、扭转时产生拟真化形变,实现水墨传输的效果控制,同时,在对系统进行需求分析的基础上,提出了系统的开发流程和总体设计。借助这一方法,采用Unity引擎技术,开发了交互式毛笔书写仿真系统。实验表明,上述系统笔画识别速度快、毛笔弯曲、扭转变形、水墨传输仿真效果好,是一套实用的毛笔书写或临摹练字的书写系统。

This paper presents a virtual brush model construction method based on position dynamics for brush bend,torsion deformation,and poor ink diffusion effect in the existing brush writing simulation technology.The meth⁃od can produce realistic deformation when brush bending or twisting during writing by a dynamic nib deformation mechanism.On the basis of the requirements analysis of the simulation system,we propose its development process and architecture design.With this method,we have developed an interactive system with Unity for the brush writing simulation.Experiments have shown that our simulation system is practical for brush writing or copy and calligraphy practice,because of the fast stroke recognition speed and the good effects of brush bend,torsion deformation and ink diffusion.
