Although Guillaume Laforge has posted the definitive Convex Hull node for ICE, I thought it would be an interesting exercise to try and hook into the CGAL geometry library and see if it was possible to use their Convex Hull (Qhull) algorithm in an ICE node. It turned out to be relatively straightforward. The Addon and C++ source is here (2013SP1, 64bit only. Only tested on a couple of machines, let me know if there are any floating dependencies I may have missed).
