Editing Convex hull (section)

===Geometric modeling===
In [[geometric modeling]], one of the key properties of a [[Bézier curve]] is that it lies within the convex hull of its control points. This so-called "convex hull property" can be used, for instance, in quickly detecting intersections of these curves.{{sfnp|Chen|Wang|2003}}

In the geometry of boat and ship design, [[chain girth]] is a measurement of the size of a sailing vessel, defined using the convex hull of a cross-section of the [[Hull (watercraft)|hull]] of the vessel. It differs from the [[skin girth]], the perimeter of the cross-section itself, except for boats and ships that have a convex hull.{{sfnp|Mason|1908}}
