Tautges, "A Set of Atomic, Dual-Based Operations for Modifying
Hexahedral Mesh Topology", presentation to UW-Madison Math Dept.
Topology Group, April 16, 2004. I wouldn't list this one, except that it's the most comprehensive presentation on this work to date. |

E. Knoop, “Combinatorial Aspects of Dual-Based Hexahedral Mesh
Modification”, Extended abstract, describing two operations (atomic pillow and face open/collapse) which (I thought were) sufficient for describing Bern et. al's flipping operations. One of these days I'll figure out whether it's two or three... |

My first publication
on the subject. Most
interesting part of the published paper was a proof that the dual of a
hex mesh is a simple polytope complex and also a simple arrangement
(pictures at right are hints on how the proof went). I've been
told that this hadn't been proven before, though I'd have thought it
would have been. There's an offhand reference to the fact in
Grunbaum (see ref in this paper), but that's all I've seen on the
subject. If you know of any other proofs (or even just
statements), I'd love to hear them. |

Timothy J. Tautges, “MOAB-SD: Integrated Structured and Unstructured Mesh Representation”, Engineering With Computers, 20, 286-293 (2004). A method of representing globs of structured and semi-structured (swept) mesh which share mesh interfaces, where that shared interface can live in the parametric space of both globs (and optionally its own). Eliminates need to store connectivity array, saving about 57% of mesh storage space compared to unstructured representation. |

Early

MOAB. Mostly qualitative, little data. |

| By far my highest-impact work. A person once told me you couldn't figure out whether a volume could be swept until you meshed the surfaces of that volume. That's a sure way to motivate me to do something. As it turns out, you only need to assign corners on linking surfaces, surface mesh schemes, and intervals (see paper for details). David White implemented this work, and it's still one of the most-used algorithms in CUBIT. Sweep group detect also came from this work (also important in assembly meshing). | |

| Describes my design & implementation for embedding attributes in geometry. Still the basis of saving meshing and other information with geometry in CUBIT (including to support save/restore to/from .cub files). This work was formative in developing my ideas on tags, used in my TSTT work. | |
| In spite of the multiple inheritance that everybody hates (including me), still the best example of a CAD-neutral and topological model-neutral geometry wrapper. API could use some polishing, but that's coming. | |
