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
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."
Thurston’s post is saved on David Eppstein’s website:
