Edge properties API

pyvoro2.edge_properties

Edge-level geometric properties for planar cells.

annotate_edge_properties(cells, domain, *, tol=1e-12)

Annotate 2D edges with basic geometric descriptors in-place.

Added edge fields (when computable): - midpoint: [x, y] - tangent: [tx, ty] unit tangent from vertex[0] -> vertex[1] - normal: [nx, ny] unit normal oriented from site -> edge - length: float - other_site: [x, y] if the neighboring site can be resolved
