パターンの展開による生成システムの研究 5 : 2×2正方形ユニットパターンから成る連続模様

p. 136-137

This study wili show possibilities of patterns generated from square basic units following a simple procedure, and demonstrate visually the number and the aspects Each sample of 13 groups of basic units classified by graphical features was assembled into 256 of 2×2 squareunit patterns, then tiled in parallel and two-dimensionally. These 256 patterns were classified by defining the rotation (R), the mirror image (M) and the inversion (I) as an identical pattern.In consequence, the 13 basic units, related to their symmetry and inversion of figure and background, revealed to generate 137 repetitive patterns in total. And their aspects showed some dynamic patterns by connected and unified, from which it was hard to imagine the basic units immediately.
