Feature-oriented writing process reproduction of Chinese calligraphic artwork

Reproducing the writing process of ancient handwritten artworks is a popular way to appreciating and learning the expert skills of Chinese calligraphy. This paper presents a system for reappearing the writing processes of calligraphic characters in different styles. In order to convey the accurate brush skill inside a stroke, a calligraphic character is first decomposed into several strokes, then the writing trajectory and footprint data of each stroke are calculated based on the edge and skeleton, which reveal the relations between shape description and writing skills, and finally the character can be rendered in the oriental ink style dynamically along the trajectory using our writing rhythm and brush footprint models. Consequently, the animation of calligraphy writing can be produced with both shape and spirit features conveyed ([see PDF]), and thus provides a visual and relax way to the comprehension of the complicated and difficult techniques in Chinese calligraphy.
