【摘要】：中国式水墨画作为一种传统艺术形式,对其进行仿真模拟逐步成为计算机应用研究领域的一项极具挑战性的课题。计算机图形学研究领域中的非真实感绘制技术从20世纪90年代中期发展至今,非真实感水墨画的绘制也是该领域的一个研究分支。完善相关艺术风格,配合交互式的绘制技术,创作出形神兼备的中国式水墨画是当前亟待解决的问题。中国水墨书画技法具有随意性,这种特性不易模仿,本文集中讨论水墨扩散以及侧锋飞白写意技法的水墨艺术效果模拟及其实现,并阐述它们应用范畴。研究基于传统艺术家较常用的笔法进行并就其特点进行仿真绘制,在前人的研究基础上提出了自己的改进算法,用以追求更加符合现实中中国水墨画的艺术效果。为实现比较理想的水墨画效果,分析和研究非真实感水墨画的绘制技法及画家的笔法、用墨用水的特点,以及不同纸张的纹理特征产生的不同效果,本文主要提出了两种水墨画写意技法的计算机仿真研究,中国式水墨画所呈现出的艺术效果变幻莫测源于水墨本身,绘画工具毛笔以及宣纸的空间结构机理之间的相互作用等。在前人研究的基础上,采用水墨动态扩散机理的物理模型,构建宣纸纤维内部结构,模拟液体在其内部流动扩散行为,改进水墨扩散规则,通过水粒子与墨粒子的运动情况与纤维元细胞之间的相互作用,实现边缘暗色化以及扩散区域毛刺感等现象,本文采用三分区域可变参系数的概率模型来模拟一种渲开的水墨扩散技法,通过对参数的调节,来形成不同的水墨扩散风格。还提出一种基于虚拟可旋转侧锋并采用多簇鬃毛笔头模型的笔刷的几何方法来模拟传统笔法侧锋飞白现象,需要获得运笔坐标笔压以及旋转方向等信息,运用OpenGL的纹理映射技术相结合,使得最终效果更佳。最终实验结果表明,采用本文提出的方法绘制出的水墨画最初边缘暗色化,最终扩散毛刺感,以及干笔飞白现象明显,模拟笔刷纹理特质等效果相对理想,再现了非真实感水墨画模拟的艺术效果,为中国传统艺术形式的传承与保留增添一种独特的形式。
[Abstract]:As a traditional form of art, the simulation of Chinese ink painting has gradually become a challenging subject in the field of computer application research. Since the development of non-realistic rendering technology in the field of computer graphics in the mid-1990s, the rendering of non-realistic ink painting is also a research branch in this field. It is an urgent problem to perfect the relevant artistic style and to create Chinese ink painting with both shapes and spirits with interactive drawing technology. The techniques of Chinese ink painting are random, which is not easy to imitate. This paper focuses on the simulation and realization of the ink and wash art effects of the Chinese ink painting techniques, and expounds their application categories. Based on the traditional artists' more commonly used strokes and their characteristics of simulation drawing, based on the previous research, we put forward their own improved algorithm, in order to pursue more realistic Chinese ink painting artistic effect. In order to realize the ideal ink painting effect, this paper analyzes and studies the drawing techniques of the non-realistic ink painting and the painters' brushwork, the characteristics of using ink water and the different effects produced by the texture features of different paper. This paper mainly puts forward the computer simulation research of two kinds of brushwork freehand brushwork techniques. The unfathomable artistic effect of Chinese ink painting originates from the interaction between the ink itself, the painting tool brush and the spatial structure mechanism of Xuan paper, etc. On the basis of previous studies, the internal structure of Xuan paper fiber was constructed by using the physical model of the dynamic diffusion mechanism of ink and water, and the diffusion behavior of liquid was simulated, and the diffusion rules of ink and wash were improved. Through the interaction between the motion of water particle and ink particle and the fiber cell, we can realize the phenomenon of edge dark color and diffusive region burr, etc. In this paper, the probabilistic model of variable parameter coefficient of three-point region is used to simulate a kind of water-ink diffusion technique, and different styles of ink diffusion are formed by adjusting the parameters. A new geometric method based on virtual rotatable lateral front and multi-cluster mane pen model is proposed to simulate the white phenomenon of the traditional brush, which needs to obtain the information of pen pressure and rotation direction. The application of OpenGL texture mapping technology combined to make the final effect better. Finally, the experimental results show that the original edge of the ink and wash paintings drawn by the method proposed in this paper is dark at the beginning, the final diffusion of burr feeling, and the obvious phenomenon of dry brush flying white, and the simulation of brush texture characteristics is relatively ideal. It reproduces the artistic effect of imitating non-realistic ink painting and adds a unique form to the inheritance and retention of Chinese traditional art form.
