An edge is given by two vertices in the 3D space, named A and B. This is for example an edge of a Voronoï cell of a 3D Delaunay tessellation.

## Active bindings

A

get or set the vertex A

B

get or set the vertex B

idA

get or set the id of vertex A

idB

get or set the id of vertex B

## Methods

### Method new()

Create a new Edge3 object.

Edge3$new(A, B, idA, idB) #### Arguments A the vertex A B the vertex B idA the id of vertex A, an integer; can be missing idB the id of vertex B, an integer; can be missing #### Returns A new Edge3 object. #### Examples edge <- Edge3$new(c(1, 1, 1), c(1, 2, 3))
edge
edge$A edge$A <- c(1, 0, 0)
edge

### Method print()

Show instance of an Edge3 object.

### Method plot()

Plot an Edge3 object.

### Method stack()

Stack the two vertices of the edge (this is for internal purpose).

#### Arguments

deep

Whether to make a deep clone.
