%description
'Math::ConvexHull' is a simple module that calculates convex hulls from a
set of points in 2D space. It is a straightforward implementation of the
algorithm known as Graham's scan which, with complexity of O(n*log(n)), is
the fastest known method of finding the convex hull of an arbitrary set of
points. There are some methods of eliminating points that cannot be part of
the convex hull. These may or may not be implemented in a future version.

The implementation cannot deal with duplicate points. Therefore, points
which are very, very close (think floating point close) to the previous
point are dropped since version 1.02 of the module. However, if you pass in
randomly ordered data which contains duplicate points, this safety measure
might not help you. In that case, you will have to remove duplicates
yourself.
