Abstract

In this paper, we establish two necessary conditions for a joint triangulation of two sets of nn points in the plane and conjecture that they are sufficient. We show that these necessary conditions can be tested in O(n3)O(n^3) time. For the problem of a joint triangulation of two simple polygons of nn vertices, we propose an O(n3)O(n^3) time algorithm for constructing a joint triangulation using dynamic programming.
