# voronoi

From tripack v1.0-1

##### Voronoi object

An `voronoi`

object is created with {`voronoi.mosaic`

}
`voronoi.mosaic`

,`plot.voronoi`

##### Arguments

- x,y
- x and y coordinates of nodes of the voronoi mosaic. Each node is a circumcircle center of some triangle from the Delaunay triangulation.
- node
- logical vector, indicating real nodes of the voronoi
mosaic. These nodes are the centers of circumcircles of triangles with
positive area of the delaunay triangulation.
If

`node[i]`

=`FALSE`

, (`c[i]`

,`x[i]`

- n1,n2,n3
- indices of neighbour nodes. Negative indices indicate dummy points as neighbours.
- tri
- triangulation object, see
`tri`

. - area
- area of triangle i.
`area[i]`

=-1 indicates a removed triangle with area 0 at the border of the triangulation. - ratio
- aspect ratio (inscribed radius/circumradius) of triangle i.
- dummy.x,dummy.y
- x and y coordinates of dummy points. They are used for plotting of unbounded tiles.
