本文提出了一种新的算法框架，一个先进的虚拟画笔，用于交互式数字绘画。该框架包括以下几个部分：一个几何模型的画笔使用层次表示，导致大量节省在每一个步骤的绘画过程中，快速在线画笔运动模拟辅助离线校准，保证准确和稳定的模拟画笔的动态行为;一种新的颜料模型，它基于随机分子的扩散过程，考虑了在浸渍时以及在绘画过程中的微妙和复杂的颜料行为;以及用户自适应组件，其使得系统能够满足不同用户的个人绘画习惯。基于该框架实现了一个原型系统。与其他虚拟画笔相比，这个新系统旨在呈现真实的画笔，因为该系统准确稳定地模拟了画笔运行的复杂绘画功能，因此能够创建具有可与真实的艺术品相媲美的细微美学细节的高质量数字绘画。先进的功能还提高了虚拟画笔的表现力，用户可以舒适地操纵。http：//www.csis.hku.hk/songhuale-brush/提供本文件的补充资料。
This paper proposes a novel algorithmic framework for an advanced virtual brush to be used in interactive digitalpainting. The framework comprises the following components: a geometry model of the brush using a hierarchicalrepresentation that leads to substantial savings in every step of the painting process; fast online brush motionsimulation assisted by offline calibration that guarantees an accurate and stable simulation of the brush's dynamicbehavior; a new pigment model based on a diffusion process of random molecules that considers delicateand complex pigment behavior at dipping time as well as during painting; and a user‐adaptation component thatenables the system to cater for the personal painting habits of different users. A prototype system has been implementedbased on this framework. Compared with other virtual brushes, this new system is designed to presenta realistic brush in the sense that the system accurately and stably simulates the complex painting functionalityof a running brush, and therefore is capable of creating high‐quality digital paintings with minute aesthetic detailsthat can rival the real artwork. The advanced features also give rise to a high degree of expressiveness ofthe virtual brush that the user can comfortably manipulate. http://www.csis.hku.hk/songhuale‐brush/ providessupplementary materials for this paper.
