## 6.849 Geometric Folding Algorithms: Linkages, Origami, Polyhedra

**6.849 Geometric Folding Algorithms: Linkages, Origami, Polyhedra (Fall 2012, MIT OCW)**. Instructor: Professor Erik Demaine. This course focuses on the algorithms for analyzing and designing geometric foldings.
Topics include reconfiguration of foldable structures, linkages made from one-dimensional rods connected by hinges, folding two-dimensional paper (origami), and unfolding and folding three-dimensional polyhedra.
Applications to architecture, robotics, manufacturing, and biology are also covered in this course.

Lecture 02 - Simple Folds |

This lecture begins with definitions of origami terminology and a demonstration of mountain-valley folding. Turn, hide, and color reversal gadgets, and proofs for folding any shape, Hamiltonian refinement, and foldability with 1D flat folding are presented.

Class 02 - Universality & Simple Folds |

This lecture begins with a folding exercise of numerical digits. Questions discussed cover strip folding in the context of efficiency, defining pseudopolynomial, seam placement, and clarifications about simple folds and flat-foldability.
