** Organization.** My recent papers are listed in two
tables, each entry of which links to full bibliographic details in a long list
below both. The first table lists regular papers,
in reverse chronological order. The second lists my Computational
Geometry Columns, again in reverse chronological order. The
detailed list into which
these two tables links includes buttons to download PDF, and/or compressed Postscript,
and perhaps includes a representative figure. If you are looking for a specific
paper, you might use Edit/Find in your browser.

* File Formats.* Most of these papers are
now in PDF format (.pdf), or compressed .pdf.gz. The older papers
are in gzip'ped
Postscript form (file.ps.gz); a few much older ones are in compressed Postscript
(file.ps.Z).
If your browser has the appropriate plugins, it will automatically gunzip (or
uncompress) to file.pdf (or file.ps), and then invoke a PDF/Postscript viewer (e.g., GhostView)
to display the paper. Some are linked to Electronic Conference Proceedings,
and some are available, in both PDF and Postscript , on the e-print
arXiv (CoRR: Computer Science
Research Repository).

Abstract |
Year |

J. O'Rourke | Two art-gallery-like problems concerning transmitters in polygons are
described,
and several open problems posed. | 2012 | |

J. O'Rourke | Can a simple spherical polygon always be triangulated?
The answer depends on the definitions of ``polygon'' and ``triangulate.'' | 2008 | |

J. O'Rourke | Two long-open problems have been solved:
(1) every sufficiently large planar point set in general position contains
the vertices of an empty hexagon;
(2) every finite collection of polygons of equal area have
a common hinged dissection.
| 2008 | |

J. O'Rourke | The new algorithm of Bobenko and Izmestiev for reconstructing the unique polyhedron
determined by given gluings of polygons is described. | 2007 | |

J. O'Rourke | A new class of art gallery -like problems inspired by wireless localization
is discussed. | 2006 | |

J. O'Rourke | A remarkable theorem is described:
"It is possible to tile the plane with non-overlapping squares
using exactly one square of each integral dimension.''
Thus, one can "square the plane.''
| 2006 | |

J. O'Rourke | The old problem of determining the chromatic number of the plane is revisited. | 2004 | |

J. O'Rourke | The algorithm of Edelsbrunner for surface reconstruction by "wrapping" a set of points in R^3 is described.
| 2004 | |

J. O'Rourke | The open problem of whether or not every pair of equal-area polygons has a hinged dissection is discussed. | 2003 | |

J. O'Rourke | The concept of pointed pseudo-triangulations is defined and a few of its applications described. | 2002 | |

J. S. B. Mitchell and J. O'Rourke | A compendium of thirty previously published open problems in computational geometry is presented. | 2001 | |

J. O'Rourke | The recent result that n congruent balls in R^d have at most 4 distinct geometric permutations is described. | 2001 | |

Joseph O'Rourke | It has recently been established by Below, De Loera, and Richter-Gebert that finding a minimum size (or even just a small) triangulation of a convex polyhedron is NP-complete. Their 3SAT-reduction proof is discussed. | 2000 | |

Joseph O'Rourke | The resolution of a decades-old open problem is described: polygonal chains cannot lock in the plane. | 2000 | |

J. O'Rourke | Recent results on curve reconstruction are described. | 2000 | |

E. Demaine, J. O'Rourke | Open problems from the 15th Annual ACM Symposium on Computational Geometry. | 1999 | |

J. O'Rourke | Two results in ``computational origami'' are illustrated. | 1999 | |

J. O'Rourke | The subquadratic algorithm of Kapoor for finding shortest paths on a polyhedron is described. | 1999 | |

P. K. Agarwal, J. O'Rourke | Problems presented at the open-problem session of the 14th Annual ACM Symposium on Computational Geometry are listed. | 1998 | |

J. O'Rourke | Several recent SIGGRAPH papers on surface simplification are described.
| 1998 | |

J. O'Rourke | The proof of Dey's new k-set bound is illustrated. | 1997 | |

J. O'Rourke | Several topics related to packing on a sphere are discussed: packing points, packing lines through the center, and packing k-flats in dimension d.
| 1997 | |

J. O'Rourke | Several results from Combinatorial Geometry by J. Pach and P.K. Agarwal are detailed. | 1997 | |

J. O'Rourke | Past accomplisments of Computational Geometry are reviewed and future directions adumbrated. | 1996 |
