應用參數式形狀文法於篆刻之造形分析、衍生與分類－以清末三大家為例

Chinese seal carving is a unique art which has been around in Chinese history for a long time. The seal style can be affected by the layout of characters, the writing style of strokes and the way of carving. There are three major goals in this dissertation. First, to analyze the form of seals by studying the structure and layout of the seals hierarchically and systematically. The basic measurable elements are extracted according to the historical bibliography. Second, a shape grammar is induced by the analytical result. Different forms of seals can be generated by the grammar by specifying parameters for basic elements in the seal structure. Third, seal forms are converted into measures of basic elements and then classified by statistical methods such as one-way analysis of variance (ANOVA) and discriminant analysis. The classified result is compared to the bibliography to find out how the style is formed for famous seal carving masters. The result of our research indicates that it is possible to generate seal forms by procedural method with parametric shape grammar. The classification for seal styles is quite accurate and acceptable. Especially the well-known styles of seal carving masters Wu Chang-Shuo, Huang Shr-Lin and Qi Bai-Shi are objectively concluded from statistical data. Moreover, the shape grammar can be used to generate seal forms of other style if suitable parameters are discovered.
