I'm working on geometry algorithms and animations: https://hgeometry.org

Right now I'm tinkering with a sub-linear visibility algorithm, and boolean operators for polygons.

Presumably in 2d? You don't mention the dimension on the main page.

Mostly 2D but some of the algorithms also work in higher dimensions. The HGeometry library explicitly encodes dimensions in the types of objects.

This is awesome
