Abstract:
This paper considers the problem of finding a simple fold of a given polygon P that “hides” (covers both sides of) the largest possible disk. We solve this problem by giving a polynomial-time algorithm to find the largest pair of equal-radius non-overlapping disks in a polygon P. The desired fold is then the perpendicular bisector of the centers of these two disks. We also present some conjectures for the more general multiple-fold case when P is a square.

Comments:
This paper is also available from the electronic proceedings as http://cgm.cs.mcgill.ca/cccg98/proceedings/cccg98-biedl-hiding.ps.gz.

Updates:
One problem explored in this paper, packing the largest pair of equal-radius disks in a given polygon, have been further developed in several followup papers. See my webpage on wrapping for a summary and references.

Erin McLeish prepared an excellent webpage describing these and related results and algorithms, including a Java applet.
