Dual Hex Meshing, Whisker Weaving


This first paper is informally known as the "hex mesh existence proof"

A Characterization of the Quadrilateral Meshes of a Surface which Admit a Compatible Hexahedral Mesh of the Enclosed Volume
Scott A. Mitchell
Proc. 13th Annual Symposium on Theoretical Aspects of Computer Science (STACS `96), Lecture Notes in Computer Science 1046, Springer, pages 465-476, 1996

See also David Eppstein's result: Linear complexity hexahedral mesh generation

Bill Thurston also wrote a newsgroup article outlining a proof that is similar to my paper: "Hexahedral decomposition of polyhedra, sci.math, 25 Oct 1993." David Eppstein has a copy of this online.
