Points

The convex hull is the smallest convex polygon containing every point — the shape a rubber band snaps to. Drag any point on the canvas to reshape the set and watch the hull recompute live. Computed here with Andrew's monotone-chain algorithm in O(n log n).

Governing equation

(a - o) \times (b - o) \leq 0 \Rightarrow pop; h = 0 of 30

Reading this result: Add points and a boundary polygon appears — the hull is the smallest convex shape wrapping them all.
