This project is part of the @thi.ng/umbrella monorepo.
Functional, polymorphic API for 2D geometry types & SVG generation.
This project is a partially ported from the Clojure version of the same name. All polymorphic operations built on @thi.ng/defmulti.

- @thi.ng/geom-clip-line - 2D line clipping (Liang-Barsky)
- @thi.ng/geom-clip-poly - 2D convex polygon clipping (Sutherland-Hodgeman)
- @thi.ng/geom-closest-point - 2D / 3D closest point / proximity helpers
- @thi.ng/geom-hull - Fast 2D convex hull (Graham Scan)
- @thi.ng/geom-isec - 2D/3D shape intersection checks
- @thi.ng/geom-isoline - Fast 2D contour line extraction / generation
- @thi.ng/geom-poly-utils - 2D polygon / triangle analysis & processing utilities
- @thi.ng/geom-resample - Customizable nD polyline interpolation, re-sampling, splitting & nearest point computation
- @thi.ng/geom-splines - nD cubic & quadratic curve analysis, conversion, interpolation, splitting
- @thi.ng/geom-subdiv-curve - Freely customizable, iterative nD subdivision curves for open / closed geometries
