WebConvex Hull Property: This means the Bézier curve defined by the given n + 1 control points lies completely in the convex hull of the given control points. The convex hull of a set of points is the smallest convex set that contains all points. In the following figure, the convex hull of the 11 control points is shown in color gray. In geometry, the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a Euclidean space, or equivalently as the set of all convex combinations of points in the subset. For a bounded subset of the plane, the convex hull may be visualized a…
