“Computational Balloon Twisting: The Theory of Balloon Polyhedra”by Erik D. Demaine, Martin L. Demaine, and Vi Hartin Proceedings of the 20th Canadian Conference on Computational Geometry (CCCG 2008), Montréal, Québec, Canada, August 2008
|
| Abstract: | This paper builds a general mathematical and algorithmic theory for balloon-twisting structures by modeling their underlying edge skeleta, evolving classic balloon animals into the new world of balloon polyhedra. |
