Documentation

jc_voronoi is a header-only C library for creating clipped 2D Voronoi diagrams from a point set. It uses Fortune’s sweep algorithm and has no external dependencies.

Add the library

Copy src/jc_voronoi.h into your project. Emit the implementation from exactly one C or C++ translation unit:

#define JC_VORONOI_IMPLEMENTATION
#include "jc_voronoi.h"

Other translation units should include the header without defining JC_VORONOI_IMPLEMENTATION.

Language support

The source supports C99, C11, C17, and C23, and can also be included from C++. Compilers that use the pre-standard C23 name should select c2x.

Next steps

• Build the command-line example
• Review the API
• Start with a complete diagram example
• Review the JavaScript API
• Use the browser and Node.js wrapper
