Calligraphic Character Formation Based on the Simulation of Brush Writing Motion

本研究的目的是开发一种利用书法知识生成毛笔汉字（汉语和日语）的计算机生成方法，为毛笔书写教育培训系统提供参考。我们已经开发了试点系统。该系统能够从在线手写文字输入中生成汉字骨架，并根据笔触、笔触、笔触运动等模型生成汉字。毛笔书写的风格主要取决于毛笔的使用方式。笔法包括笔头的方向、弧度、笔头的转动、笔画结束点的刷上。我们根据前面提到的毛笔技巧，对书法知识进行了复习。为了模拟真实的笔触运动，我们设计了笔触形式，即笔触在书写平面（纸）上的形状。在笔刷模拟过程中，该系统可以控制笔刷触碰的大小和方向。该系统以系统数据库中的骨架为基础，模拟了真实的毛笔书写动作和情况。因此，系统用户（或学员）可以从本系统的书法知识数据库中学习笔触等毛笔书写技能。我们认为这个系统对想要学习如何用毛笔写漂亮的日语字母的学生很有用。

The purpose of the research is to develop a method of computer formation of brush-written Kanji (Chinese and Japanese) characters using calligraphic kowledge, which is for educational training system of brush writing. We have developed the pilot system. This system can generate skeltons of character from on-line handwritten character input, and formates the calligraphic character based on models of brush shape, touch on paper, and brush writing movement.The style of brush handwriting depens mainly on the way of using the writing brush. Brush writing skills include the direction of brush at the beginning, curvature, brush turning, and the brush-up at the termination poin in a stroke. We have revised the calligraphic knowledge according to the aforementioned brush writing skills. For simulating real brush movement, We devised the brush contact form that is the brush shape on the writing plane (paper) as a brush-touch. The system can control the size and direction of this brush-touch during the brush simulation. The system simulates the real brush writing motion and situation based on the skeltons in the data base of this system. Accordingly, the system user (or trainee) can learn the skills of brush handwriting such as the brush-touch from the calligraphic knowledge data base in this system.We consider that this system is useful for students who want to learn how to beautifully write Japanese letters by brush pen.
