Struct voronoice::VoronoiCell

pub struct VoronoiCell<'v> { /* fields omitted */ }

Represents a Voronoi cell. This is an ergonomic way to access cell details.

Use Voronoi::cell() or Voronoi::iter_cells() to obtain an instance of this type.

Implementations

impl<'v> VoronoiCell<'v>

pub fn site_position(&self) -> &Point

Gets a reference to the position of the site associated with this cell.

Examples

 use voronoice::*;
 let sites = vec![Point { x: 0.0, y: 0.0 }, Point { x: 0.5, y: 0.0 }, Point { x: 0.0, y: 0.5 }];
 let v = VoronoiBuilder::default()
     .set_sites(sites.clone())
     .build()
     .unwrap();
 // the first site generated by generate_circle_sites is at the origin
 assert_eq!(&sites[0], v.cell(0).site_position());
 assert_eq!(&sites[1], v.cell(1).site_position());
 assert_eq!(&sites[2], v.cell(2).site_position());

pub fn triangles(&self) -> impl Iterator<Item = usize> + 'v + Clone

Gets an iterator the indices of the triangles of the dual Delauney triangulation that are associated with this cell. The Voronoi cell vertices are the circumcenters of the associated Delauney triangles. This is a way to index into the underlying Delauney triangles.

If this cell is on the hull of the diagram (cell.is_on_hull() == true), or has had one of its edges clipped,

pub fn vertices(&self) -> impl Iterator<Item = &Point>

Gets an iterator for the vertices of

pub fn is_on_hull(&self) -> bool

Returns a boolean indicating whether this cell is on the hull (edge) of the diagram.

Trait Implementations

impl<'v> Clone for VoronoiCell<'v>

pub fn clone(&self) -> VoronoiCell<'v>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'v> Debug for VoronoiCell<'v>

pub fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
