# Voronoi Diagram (G Dataflow)

Last Modified: June 25, 2019

Computes the Voronoi diagram of specified points in a plane.  ## x

X-coordinates of the points in the plane. You must specify at least three elements in this input. ## y

Y-coordinates of the points in the plane. You must specify the same number of elements in y and x. ## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error  If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error ## Voronoi x

X-coordinates of the Voronoi points. ## Voronoi y

Y-coordinates of the Voronoi points. ## Voronoi edges

An n-by-2 array of indexes of the Voronoi points, where n is the number of edges in the Voronoi diagram. Each row of Voronoi edges represents an edge of the Voronoi diagram defined by the indexes. ## error out

Error information.

The node produces this output according to standard error behavior.

## Voronoi Diagrams

For n given points in the plane, the Voronoi diagram divides the plane into n Voronoi cells. Each given point belongs to one Voronoi cell. The point in a Voronoi cell is closer to the corresponding given point than to any of the other given points.

The following figure shows an example of a Voronoi diagram of eight given points. Where This Node Can Run:
