rigidfold
Rigidfold is a method of origami that involves folding paper into complex shapes using a series of precise, rigid movements. Unlike traditional origami, which often relies on more flexible folds, rigidfold emphasizes the use of straight lines and sharp creases to create intricate designs. This technique was popularized by Robert Lang, an American mathematician and origami artist, who has extensively documented and promoted rigidfolding in his books and online resources.
The key principle of rigidfold is the use of "rigid units," which are sections of the paper
Rigidfolding is particularly well-suited for creating models with sharp edges and angles, such as polyhedra, mechanical
Rigidfold has gained popularity among origami enthusiasts and has been featured in various exhibitions and competitions.
