虚拟毛笔模型研究综述

A Survey of Virtual Hairy Brush

毛笔是传承中国传统文化不可或缺的载体,虚拟毛笔模型的研究主要是对真实毛笔的艺术表现效果用计算机进行模拟,也包括对毛笔外形建模。基于对毛笔特点的归纳分析,对近20年来虚拟毛笔模型的研究历程及主要建模方法做了综述,详细介绍了几种典型的虚拟毛笔模型,归纳了它们的建模思想,总结了各自的特点,并讨论了与毛笔建模相关的纸笔交互及墨扩散效果问题,最后结合实际应用与研究提出了虚拟毛笔今后的发展方向。

Chinese hairy brush does a very important role in inheriting the traditional culture of China. Since Strassmann from MIT Media Laboratory proposed the first hairy brush model in 1986, more and more researches have been focused on the modeling of virtual hairy brush. These researches were mainly on how to simulate the art effect and shape of the traditional hairy brush. Most of virtual brush models proposed in the latest 20 years were reviewed, and several classical models such as Srassmann＇s model, elastic mechanics-based model, body-based model, physically-based model and pure parameterized model were analysed in detail, and the thinking in these models was summed up. Two corresponding issues to model the hairy brush, namely the interaction between hairy brush and paper, and the simulation of ink diffusion effect were also discussed Subsequently, the future developing directions concerned with the virtual hairy brush were forecasted.
