polygon - a package to manipulate non self-intersecting polygons

Overview

This package provides routines for 2D polygons. That is non self-intersecting multi-edged shapes with more than 2 vertex points.

API

The API provided by this package is avalble using go doc zappem.net/pub/math/polygon. It can also be browsed on the go.dev website: package zappem.net/pub/math/polygon.

Example

See the https://zappem.net/pub/project/polygons/ example.

TODO

• Generally, I’m using the code for a while to gain some confidence that I’ve not missed an important detail.

Here are some known issues potentially gating release of v1.0.0.

• The polymark spirals example generates polygon.Shapes that can take some time to Union.

• Also, running svgpoly outlines on these spirals has a really hard time --inverse 5 generating reliable inverses.

• The glase example has support for a LASER caution icon. Ideally that could be Uniond but it seems to require it be dealt with in two parts.

Some things to look into after v1.0.0.

• Performance
