到了1950至60年代,日本摺紙大師吉澤章提出了一套革命性的摺紙圖解系統。他在1954年發表的《新摺紙藝術》(新らしいおりがみ芸術)中首次介紹了這套系統,其中運用了點線和虛線來分別代表山折和谷折,並融入了如「吹氣」和「圓形」等新符號。這套方法引起了塞繆爾·蘭德列特(英语:Samuel Randlett)和羅伯特·哈賓(英语:Robert Harbin)的注意,他們又增加了如「旋轉」和「放大」等符號,並將其定為標準。吉澤-蘭德列特系統於1961年首次在蘭德列特的《摺紙藝術》(Art of Origami)中被詳細介紹[1],並迅速成為全球摺紙界的通用標準,至今仍被廣泛使用。

Pages 1–30 are an excellent introduction to most of these skills. Each of these 13 models is designed to let you practice one skill several times. Unfortunately, the remaining 24 models leave out lots of pre-creases.
Peter Engel. Origami from Angelfish to Zen. Dover Publications, Mineola, NY. Copyright 1989 by Peter Engel. ISBN 0-486-28138-8 (pbk.)
Pages 1–88 explain how the crease patterns of the classic bases are related to each other, how they are examples of fractal design, and how it is possible to generate arbitrarily complex origami designs.

This book shows how crease patterns and folding techniques are related to the large-scale structure of a model. It also shows how closed-unsinking was derived, using Lang's TreeMaker software for prototyping arbitrarily complex origami designs.

This is an excellent book about modular origami, and serves as a great introduction to geometric models and designs.
