Parallel triangulation of a polygon in two calls to the trapezoidal map

Research output: Contribution to journalArticle

Abstract

We give a parallel method for triangulating a simple polygon by two (parallel) calls to the trapezoidal map computation. The method is simpler and more elegant than previous methods. Along the way we obtain an interesting partition of one-sided monotone polygons. Using the best-known trapezoidal map algorithm, ours run in time O(log n) using O(n) CREW PRAM processors.
