Chalc Documentation#

Chalc is a Python package for computing the persistent homology of chromatic alpha complexes of coloured point clouds in Euclidean space. Chalc is written in C++ and relies on the Computational Geometry Algorithms Library (CGAL) for fast and accurate geometric computations, and Phimaker for persistent homology calculations.
