It also performs **polygon offsetting**, and **Constrained Delaunay Triangulation**. This is a major update of my original \u003ca href=\"https://sourceforge.net/projects/polyclipping/\"\u003e\u003cb\u003eClipper\u003c/b\u003e\u003c/a\u003e library that was written about 15 years ago. That library I\u0027m now calling \u003cb\u003eClipper1\u003c/b\u003e, and while it still works very well, Clipper2 is just [better](https://www.angusj.com/clipper2/Docs/Changes.htm).\n\n```diff\n- CAUTION: The triangulation code is buggy and I regret releasing it when I did.\n- I\u0027m working on fixes but these may still be weeks away. Sorry.\n```\n\n### Compilers\n\u003cb\u003eClipper2\u003c/b\u003e can be compiled using any one of three supported programming languages: C++, or C#, or Delphi Pascal. The library can also be accessed from other languages by dynamically li",
