Koebe-Lib is a library for investigating inversive geometry of circles. It has facilities for representing circles / disks one the 2-sphere as well as in other geometries such as Euclidean and Oriented Projective. It includes Ken Stephenson’s CirclePack as a dependency for performing circle packing. The code is written in Kotlin and can be used as a Kotlin library. We also have a small application included called SphericalSketch which displays the 2-sphere and a python coding window and allows figures to be constructed using python.

Escher is a programming language for coding conformal subdivision tilings. Currently, Escher’s code resides within Koebe-Lib though it should probably eventually fork off into its own project.
