geos_delaunay_triangles: Delaunay triagulations and Voronoi diagrams

In geos: Open Source Geometry Engine ('GEOS') R API

Delaunay triagulations and Voronoi diagrams

Description

These functions return one triangulation/diagram per feature as a multi geometry. These functions are not vectorized along their parameters.

Usage

geos_delaunay_triangles(geom, tolerance = 0)

geos_constrained_delaunay_triangles(geom)

geos_delaunay_edges(geom, tolerance = 0)

geos_voronoi_polygons(geom, env = NULL, tolerance = 0)

geos_voronoi_edges(geom, env = NULL, tolerance = 0)

Arguments

geom	A GEOS geometry vector whose nodes will be used as input.
tolerance	A snapping tolerance or 0 to disable snapping
env	A boundary for the diagram, or NULL to construct one based on the input

Value

A GEOS geometry vector of length geom

Examples

geos_delaunay_triangles("MULTIPOINT (0 0, 1 0, 0 1)")
geos_delaunay_edges("MULTIPOINT (0 0, 1 0, 0 1)")

geos_voronoi_polygons("MULTIPOINT (0 0, 1 0, 0 1)")
geos_voronoi_edges("MULTIPOINT (0 0, 1 0, 0 1)")
