Convex-hull feature adaptation

WebConvex Hull Definition: Given a finite set of points P={p1,… ,pn}, the convex hull of P is the smallest convex set C such that P⊂C. p1 p2 pn C Examples Two Dimensions: The convex hull of P={p1,… ,pn} is a set of line segments with endpoints in P. p1 p2 pn C Examples Three Dimensions: The convex hull of P={p1,… ,pn} is a triangle mesh ... WebThe convex hull of the red set is the blue and red convex set. 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 ...
