gen_edges {quollr}

Generate edge information

Description

This function generates edge information from a given triangular object, including the coordinates of the vertices and the from-to relationships between the vertices.

Usage

gen_edges(tri_object)

Arguments

tri_object

The triangular object from which to generate edge information.

Value

A data frame containing the edge information, including the from-to relationships and the corresponding x and y coordinates.
