C

The public C API is split across two single-header files:

• jc_voronoi.h generates and traverses Voronoi diagrams and Delaunay adjacency.
• jc_voronoi_clip.h adds a ready-made clipper for convex polygons.

Both headers are C99-compatible and can be included from C++. They allocate no caller-visible objects: callers provide input arrays and output structures, while the generated diagram owns its internal storage until jcv_diagram_free is called.

Typical lifecycle

1. Zero-initialize a jcv_diagram.
2. Generate a full Voronoi diagram with jcv_diagram_generate, or adjacency only with jcv_delaunay_generate.
3. Read sites, vertices, and edges through the accessors and iterators.
4. Call jcv_diagram_free exactly once when finished.

jcv_diagram diagram = {0};
jcv_diagram_generate(num_points, points, NULL, NULL, &diagram);

/* Read diagram data here. */

jcv_diagram_free(&diagram);

Pointers returned by the API and pointers stored in edge values belong to the diagram. They become invalid when that diagram is regenerated or freed.
