Packages starting with 'C'

CyTriangle wraps Jonathan Shewchuk's Triangle library via Cython to generate Delaunay triangulations, constrained Delaunay triangulations, Voronoi diagrams, and high-quality triangular meshes suitable for finite element analysis.

cyvcf2 is a Cython wrapper around htslib that parses VCF and BCF genomic variant files at speed, including region-based queries, and returns numpy arrays for immediate downstream analysis.

Install it if you need to parse VCF or BCF files in Python and want speed and direct numpy integration; avoid it only if you cannot tolerate the C compiler…
