Package Exports
- @thi.ng/geom
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@thi.ng/geom) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
This project is part of the @thi.ng/umbrella monorepo.
About
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.
