Lecture 10: Polyhedron (un)folding in general, polyhedron unfolding in particular: edge unfoldings, general unfoldings, main questions and results, curvature, source unfolding, star unfolding, ununfoldable polyhedra
Page 3: General unfolding of convex polyhedra: shortest paths, geodesics, cut locus/ridge tree, source unfolding, star unfolding, extension to higher dimensions, continuous blooming, failure to extend to nonconvex polyhedra.
You can view a paper about the star unfolding by Agarwal, Aronov, O'Rourke, and Schevon (a followup to the original Aronov and O'Rourke paper).
These are rough, personal lecture notes handwritten by Erik Demaine used during lecture. Their primary purpose is for reading/review by students of the class. Accessibility
