** Proximate cause: Because it was holed beneath the waterline, water entered the hull and the ship became denser than the water which supported it, so it couldn't stay afloat.

** Ultimate cause: Because the ship hit a rock which tore open the hole in the ship's hull.

** point set triangulation, division of the convex hull of a point set into triangles using only that set as triangle vertices
