Writing brush calligraphy expressing method based on force information

Abstract

A writing brush calligraphy expressing method based on force information adopts a three-dimensional force sensor to obtain three-dimensional handwriting force vector information generated by contacting writing brush head hairs with the plane of paper, namely the three-dimensional force sensor can sense and output three-dimensional handwriting dynamic force information changes acted on the three-dimensional force sensor in real time when a writing brush handwriting process happens. By collecting and converting the information, a brush touch area generated by plane touch of the writing brush head hairs and paper is calculated, operation and processing on the brush touch area are achieved according to the force information so as to form handwriting marks, and spreading mode of ink at the handwriting mark edges is calculated. Especially an ink cross-shaped spreading method is adopted to finish calculation on ink spreading at the handwriting mark edges, and finally the writing brush calligraphy expressing effect under the force information is achieved. The writing brush calligraphy expressing method based on the force information enables people who write to truly experience expressing difference of writing brush calligraphy caused by different handwriting forces, and provides a novel technological method for writing brush calligraphy characters and calligraphy training on a computer or writing brush calligraphy correction.

Description

technical field [0001] The invention relates to the field of computer information and computer art simulation technology, in particular to a brush calligraphy expression method based on force information. Background technique [0002] The art of Chinese brush calligraphy has a history of thousands of years. All the literati throughout the ages like to "splash ink" and express their feelings with the help of brushes. Countless calligraphers have left us exquisite artistic treasures. As a calligraphy tool, the brush has the characteristics of easy operation and rich expressiveness. With the rapid development of computer technology, more and more scholars have begun to pay attention to the research of brush calligraphy expression. Brush calligraphy is extremely expressive and can produce rich visual effects, which mainly depend on the complex and changeable shape of brush pens and the uncertainty of ink spreading on paper. Therefore, when simulating the effect of brush callig...

Problems solved by technology

[0005] In the prior art, the expression of brush calligraphy effects is realized through computer graphics or computer-specific algorithms, such as using brush and paper graphics to simulate the effect of writing on paper with a brush, or using the raindrop model of a brush to achieve various brush calligraphy special effects, but most of the existing technologies realize the rendering of brush calligraphy or ink painting by setting complex parameters or using complex specific equipment, which is not practical for ordinary users, and its calculation complexity is high, which affects computer performance. The requirements are high, especially these algorithms do not actually reflect the physical process of brush calligraphy. In fact, the process of brush calligraphy is a process of force action and feedback, that is, the formation of brush writing is driven by the force of human hands. The special brush writing style formed by this process, such as the beauty of shape, expression, charm, artistic conception and momentum, is formed by the writer's writing force, and this process is formed naturally
