【摘要】：中国书画的计算机仿真是计算机技术和传统书画艺术相结合的产物,不仅具有重要的理论研究价值和实用价值,而且对传承、推广传统中华文化具有重要的现实意义。在虚拟环境中自然、逼真地实现书画艺术作品效果的模拟是中国书画计算机仿真的重要目标,而毛笔行为仿真是提高书画艺术作品效果模拟的关键,因此在虚拟绘制中进行毛笔受力变形和受力运动仿真研究具有重要的意义。本文在深入分析毛笔物理性能、归纳毛笔建模方法以及总结毛笔笔法的基础上,通过分析力对毛笔变形的影响机理,采用弹簧-振子模型构建了包括几何模型和力学模型的毛笔力反馈仿真新模型；在此基础上通过分析毛笔受力变形和受力运动及其影响因素,提出基于力反馈技术的毛笔行为仿真方法,并根据毛笔受力后的形态变化和运动变化,研究了笔道绘制算法,实现了笔道的实时绘制,提高了绘制过程的真实感；最后将毛笔行为研究成果应用到汉字楷书化仿真中,实现了毛笔书法的风格化模拟。为验证毛笔模型和毛笔行为仿真方法的有效性,本文在开发的基于力反馈技术的虚拟绘制系统中进行了一系列仿真实验。实验结果表明,毛笔力反馈仿真模型不仅能反映出实际毛笔的物理性能,而且能体现出毛笔的受力变形和运动规律。用户使用力反馈设备控制虚拟毛笔绘制时,可实时感知力的变化,并能通过调整压力和位置实时控制虚拟毛笔的形态和运动,降低了绘制过程的难度,增加了绘制过程的真实感和仿真效果的逼真性,为中国书画计算仿真的深入研究提供一定的参考。
[Abstract]:The computer simulation of Chinese calligraphy and painting is the product of the combination of computer technology and traditional calligraphy and painting art. It not only has important theoretical research value and practical value, but also has important practical significance for inheriting and popularizing traditional Chinese culture. In the virtual environment, it is an important goal of computer simulation of Chinese calligraphy and painting to realize realistic simulation of the effect of calligraphy and painting works, and the simulation of brush behavior is the key to improve the simulation of the effect of calligraphy and painting works. Therefore, it is of great significance to simulate the mechanical deformation and motion of brush in virtual rendering. Based on the deep analysis of the physical properties of the brush, the modeling method of the brush and the conclusion of the brush method, the mechanism of the influence of the force on the deformation of the brush is analyzed in this paper. A new model of brush force feedback simulation including geometric model and mechanical model is constructed by using spring-oscillator model. On this basis, by analyzing the force deformation and force movement of brush and its influencing factors, a method of brush behavior simulation based on force feedback technique is put forward. According to the morphological change and motion change of brush under force, the algorithm of drawing brush path is studied. The real-time rendering of pen and trace is realized, and the realism of the rendering process is improved. Finally, the research results of brush behavior are applied to the simulation of regular script of Chinese characters, and the stylistic simulation of brush calligraphy is realized. In order to verify the effectiveness of brush model and brush behavior simulation method, a series of simulation experiments are carried out in the virtual rendering system based on force feedback technology. The experimental results show that the simulation model of brush force feedback can not only reflect the physical properties of the actual brush, but also reflect the mechanical deformation and motion law of the brush. When the user uses the force feedback device to control the virtual brush drawing, it can feel the change of the virtual brush force in real time, and can control the shape and movement of the virtual brush by adjusting the pressure and position, thus reducing the difficulty of the rendering process. It increases the realism of the rendering process and the verisimilitude of the simulation effect, and provides a certain reference for the further study of the Chinese calligraphy and painting computer simulation.
