JUNIOR COLLOQUIUM


SPEAKER:  Dr. John Bowers, Univ. of Massachusetts

TITLE:  Rigidity of Origami

ABSTRACT:  In a seminal work on computational origami, Robert Lang proposed

a design method called "TreeMaker". It produces a crease pattern for a polygonal sheet of paper such that an isometric 3D folded state exists. Though TreeMaker has been around for

nearly 20 years, many of its mathematical and algorithmic properties have yet to be investigated. In this talk I will show that TreeMaker often produces crease patterns which are not rigidly foldable --- there is no continuous folding process leading to the 3D state in which the faces are kept as rigid panels whose shared edges act as hinges.  

 

This result is joint work with Ileana Streinu.
