* Package name : libmath-convexhull-monotonechain-perl Version : 0.01 Upstream Author : Steffen Mueller, <smuel...@cpan.org> * URL : https://metacpan.org/release/Math-ConvexHull-MonotoneChain * License : GPL-1+ or Artistic (same as Perl) Programming Lang: Perl/C Description : Perl module to calculate a convex hull using Andrew's monotone chain algorithm This (XS) module optionally exports a single function convex_hull which calculates the convex hull of the input points and returns it. Andrew's monotone chain convex hull algorithm constructs the convex hull of a set of 2-dimensional points in O(n*log(n)) time. It does so by first sorting the points lexicographically (first by x-coordinate, and in case of a tie, by y-coordinate), and then constructing upper and lower hulls of the points in O(n) time. It should be somewhat faster than a plain Graham's scan (also O(n*log(n))) in practice since it avoids polar coordinates. This package is a dependency for Slic3r (ITP #689636) and will be maintained under the umbrella of the Debian Perl Group. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
