The **split-polygon** library provides a tiny, dependency‑free function that cuts a *convex* polygon by an arbitrary hyper‑plane (using the Sutherland‑Hodgman clipping algorithm). It works in any number of dimensions and can be used both on the server (Node.js) and in the browser, returning the polygon’s positive and/or negative portions; it’s aimed at developers needing fast geometric clipping for graphics, computational geometry, or physics simulations.
