## 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 19 - Refolding & Smooth Folding |

This lecture begins with a problem involving unfolding and refolding. Examples of smooth foldings and unfoldings are given, followed by a problem involving the wrapping of a sphere and a proof that the wrappings are contractive.

Class 19 - Refolding & Kinetic Sculpture |

This class first covers research findings involving common unfoldings of boxes. Several examples of kinetic sculptures and machines are shown, including Theo Jansen's Strandbeests and Arthur Ganson's works at the MIT Museum.
