Thomas Neidhart updated MATH-749:
---------------------------------

    Description: 
It would be nice to have convex hull implementations for 2D/3D space. There are 
several known algorithms [http://en.wikipedia.org/wiki/Convex_hull_algorithms]:

 * Graham scan: O(n log n)
 * Incremental: O(n log n)
 * Kirkpatrick-Seidel: O(n log h)
 * Chan: O(n log h)

The preference would be on an algorithm that is easily extensible for higher 
dimensions, TBD.

  was:It would be nice to have an implementation of Graham's scan algorithm to 
compute the convex hull of a set of points in a plane.
