This project is part of the @thi.ng/umbrella monorepo.

About

2D polygon/polyline analysis & processing utilities. This is a support package for @thi.ng/geom.

  • signed 2D polygon & triangle area
  • triangle barycentric coord conversion
  • nD point cloud bounding box
  • 2D poly center of weight
  • nD point cloud centroid
  • 2D circumcenter
  • 2D polygon convexity classification
  • 2D equilateral triangle
  • polygon / polyline perimeter

Current implementations partially based on toxiclibs (Java) and Clojure version of thi.ng/geom.
