convex hull

smallest convex set containing a given geometric object

Note to entry: "Smallest" is the set theoretic smallest, not an indication of a measurement. The definition can be rewritten as "the intersection of all convex sets that contain the geometric object". Another definition in a Euclidean space `bbb"E"^n` is the union of all lines with both end points in the given geometric object. `C = A."convexHull" <=> [C."convex" = "TRUE"] ^^ [A sub C] ^^ [[B."convex" = "true", A sub B] => [A sube C sube B]]`
