Presets

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

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

About this simulation

The full Convex Hull tool models a ranking model with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions

How do I simulate a ranking model?
Open this page and use the live Convex Hull tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
Is it free?
Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
Can I use my own numbers?
Absolutely — every input is adjustable, and with data import you can drive a ranking model from your own measurements.
