draw.tpolytope: Draw a 2-D or 3-D tropical polytope

Description

This command draws a three dimensional tropical polytope

Usage

draw.tpolytope.3d(D, col_lines, col_verts, plot = TRUE, tadd = max)
draw.tpolytope.2d(D, col_lines, col_verts, plot = TRUE, tadd = max)

Value

2-D or 3-D rendering of a tropical polytope.

Arguments

D

matrix of vertices of a tropical polytope; rows are the vertices

col_lines

string; color to render the polytope.

col_verts

string; color to render the vertices.

plot

logical; initiate new plot visualization or not.

tadd

function; max indicates max-plus addition, min indicates min-plus addition. Defaults to max
