虚拟毛笔建模研究现状与展望

摘要

Virtual brush modeling is a key technology in virtual painting.In order to truly reflect the characteristics of the real brush,enhance the reality of virtual painting,this paper reviewed the current research of virtual brush modeling.It summarised the basic idea,merits and demerits of typical modeling methods.It also discussed simulation effects of empirical-based modeling method and physical-based modeling method.Then,it briefly analyzed the interaction between brush and paper,paper and ink, human and computer,which had effects on virtual brush modeling.Finally,it analyzed the main difficulties and problems in vir-tual painting,and put forward the future research directions concerned with the virtual brush modeling.%为了真实地体现实际毛笔的特点，增强虚拟绘制真实感，通过对虚拟毛笔建模现状综述，归纳了典型建模方法的基本思想和优缺点，探讨了基于经验方法和基于物理方法的模拟效果；还简要分析了笔纸交互、纸墨交互及人机交互设备对虚拟毛笔建模的影响。最后分析了目前虚拟绘制中存在的主要难点和问题，指出了今后虚拟毛笔建模的研究方向。
